REGULATION 2

DEFINITIONS

For the purpose of this Chapter, unless expressly provided otherwise

(a) (i) The subdivision load line is the waterline used in determining the subdivision of the ship.

(ii) The deepest subdivision load line is the waterline which corresponds to the greatest draught.

(b) The length of the ship is the length measured between perpendiculars taken at the extremities of the deepest subdivision load line.

(c) The breadth of the ship is the extreme width from outside of frame to outside of frame at or below the deepest subdivision load line.

(d) The bulkhead deck is the uppermost deck up to which the transverse watertight bulkheads are carried.

(e) The margin line is a line drawn at least 3 inches (or 76 millimeters) below the upper surface of the bulkhead deck at side.

(f) The draught is the vertical distance from the moulded base line amidships to the subdivision load line in question.

(g) The permeability of a space is the percentage of that space which can be occupied by water.The volume of a space which extends above the margin line shall be measured only to the height of that line.

(h) The machinery space is to be taken as extending from the moulded base line to the margin line and between the extreme main transverse watertight bulkheads bounding the spaces devoted to the main and auxiliary propelling machinery, boilers when installed and all permanent coal bunkers. In the case of unusual arrangements, the Administration may define the limits of the machinery spaces.

(i) Passenger spaces are those which are provided for the accommodation and use of passengers, excluding baggage, store, provision and mail rooms. For the purposes of Regulations 4 and 5, spaces provided below the margin line for the accommodation and use of the crew shall be regarded as passenger spaces.

PART B.—SUBDIVISION AND STABILITY

(PART B APPLIES TO PASSENGER SHIPS ONLY EXCEPT THAT REGULATION IS ALSO APPLIES TO CARGO SHIPS)

REGULATION 3

FLOODABLE LENGTH

(a) The floodable length at any point of the length of a ship shall be determined by a method of calculation which takes into consideration the form, draught and other characteristics of the ship in question.

(b) In a ship with a continuous bulkhead deck, the floodable length at a given point is the maximum portion of the length of the ship, having its centre at the point in question, which can be flooded under the definite assumptions hereafter set forth in Regulation 4 without the ship being submerged beyond the margin line.

(c) (i) In the case of a ship not having a continuous bulkhead deck, the floodable length at any point may be determined to an assumed continuous margin line which at no point is less than 3 inches (or 76 millimeters) below the top of the deck (at side) to which the bulkheads concerned and the shell are carried watertight.

(ii) Where a portion of an assumed margin line is appreciably below the deck to which bulkheads are carried, the Administration may permit a limited relaxation in the water tightness of those portions of the bulkheads which are above the margin line and immediately under the higher deck.

REGULATION 4

PERMEABILITY

(a) The definite assumptions referred to in Regulation 3 relate to the permeabilities of the spaces below the margin line.

In determining the floodable length, a uniform average permeability shall be used throughout the whole length of each of the following portions of the ship below the margin line:

(i) the machinery space as defined in Regulation 2;

(ii) the portion forward of the machinery space; and

(iii) the portion abaft the machinery space.

(b) (i) For steamships the uniform average : permeability throughout the machinery space shall be determined from the formula—

80 + 12.5
(a - c),
where

(v)

a = volume of the passenger spaces, as defined in Regulation 2, which are situated below the margin line within the limits of the machinery space.

c = volume of between deck spaces below the margin line within the limits of the machinery space which are appropriated to cargo, coal or stores.

v = whole volume of the machinery space below the margin line.

(ii) For ships propelled by internal combustion engines, the uniform average permeability shall be taken as 5 greater than that given by the above formula.

(iii) Where it is shown to the satisfaction of the Administration that the average permeability as determined by detailed calculation, is less than that given by the formula, the detailed calculated value may be used. For the purpose of such calculation, the permeabilities of passenger spaces, as defined in Regulation 2, shall be taken as 95, that of all cargo, coal and store spaces as 60, and that of double bottom, oil fuel and other tanks at such values as may be approved in each case by the Administration.

(c) Except as provided in paragraph (d) below, the uniform average permeability throughout the portion of the ship before (or abaft) the machinery space shall be determined from the formula—

63 + 35
a
v

where:—

a = volume of the passenger spaces, as defined in Regulation 2, which are situated below the margin line, before (or abaft) the machinery space, and

v = whole volume of the portion of the ship below the margin line before (or abaft) the machinery space.

(d) In the case of a ship which is permitted under Regulation 22 of Chapter III to carry a number of persons on board in excess of the lifeboat capacity provided, and is required under paragraph (d) of Regulation 1 in this Chapter to comply with special provisions, the uniform average permeability throughout the portion of the ship before (or abaft) the machinery space shall be determined from the formula—

95 - 35
b
v

where:—

b = the volume of the spaces below the margin line and above the tops of floors, inner bottom, or peak tanks, as the case may be, which are appropriated to and used as cargo spaces, coal or oil fuel bunkers, store rooms, baggage and mail rooms, chain lockers and fresh water tanks, before (or abaft) the machinery space; and

v = whole volume of the portion of the ship below the margin line before (or abaft) the machinery space.

In the case of ships engaged on services where the cargo holds are not generally occupied by any substantial quantities of cargo, no part of the cargo spaces is to be included in calculating "b."

(e) In the case of unusual arrangements the Administration may allow, or require, a detailed calculation of average permeability for the portions before or abaft the machinery spaces. For the purpose of such calculation the permeability of passenger spaces as defined in Regulation 2 shall be taken as 95, that of spaces containing machinery as 80, that of all cargo, coal and store spaces as 60, and that of double bottom, oil fuel and other tanks at such value as may be approved in each case by the Administration.

(f) If a between deck compartment between two watertight transverse bulkheads contains any passenger of crew space, the whole of that compartment, less any space completely enclosed within permanent steel bulkheads and appropriated to other purposes, shall be regarded as passenger space. If, however, the passenger or crew space in question is completely enclosed within permanent steel bulkheads, only the space so enclosed need be considered as passenger space.

REGULATION 5

PERMISSIBLE LENGTH OF COMPARTMENTS

(a) Ships shall be as efficiently subdivided as is possible having regard to the nature of the service for which they are intended. The degree of subdivision shall vary with the length of the ship and with the service, in such manner that the highest degree of subdivision corresponds with the ships of greatest length, primarily engaged in the carriage of passengers.

(b) Factor of Subdivision.—The maximum permissible length of a compartment having its centre at any point in the ship's length is obtained from the floodable length by multiplying the latter by an appropriate factor called the factor of subdivision.

The factor of subdivision shall depend on the length of the ship, and for a given length shall vary according to the nature of the service for which the ship is intended. It shall decrease in a regular and continuous manner—

(i) as the length of the ship increases, and

(ii) from a factor A, applicable to ships primarily engaged in the carriage of cargo, to a factor B, applicable to ships primarily engaged in the carriage of passengers.

The variations of the factors A and B shall be expressed by the following formulae (I) and (II) where L is the length of the ship as defined in Regulation 2:—

A =
L in feet
+ .18

__190__
(L = 430
L—198
and upwards)
A =
L in meters
+ .18

.......... (I)
__58.2__
(L = 131 and
L—60
upwards)
B =
L in feet
+ .18

__100__
(L = 260 and
L—138
upwards)
B =
L in meters
+ .18
 
......... (II)
__30.3__
(L = 79 and
L—42
upwards)

 

(c) Criterion of Service.—For a ship of given lengtn the appropriate factor of subdivision shall be determined by the Criterion of Service Numeral (hereinafter called the Criterion Numeral) as given by the following formula; (III) and (IV) where:—

C3 = the Criterion Numeral;

L = length of the ship, as defined in Regulation 2;

M = the volume of the Machinery space, as defined in Regulation 2; with the addition thereto of the volume of any permanent oil fuel bunkers which may be situated above the inner bottom and before or abaft the machinery space;

P = The whole volume of the passenger spaces below the margin line, as defined in Regulation 2;

V = the whole volume of the ship below the margin line;

P1 = KN where:—

N = number of passengers for which the ship is to be certified, and

K has the following values—

Value of K.

Length in feet and volumes in cubic feet........................ 6 L.

Length in meters and volumes in cubic meters.................... 056 L.

Where the value of KN is greater than the sum of P and the whole volume of the actual passenger spaces above the margin line, the figure to be taken as Pi is the sum of 2/3 KN, whichever is the greater.

When P1 is greater than P—

C3 = 72
M + 2P1
........................... (III)
M + P1-P

 

and in other cases—

C3 = 72
M + 2P1
........................... (IV)
V

 

For the ships not having a continuous bulkhead deck the volumes are to be taken up to the actual margin lines used in determining the floodable lengths.

(d) Rules for Subdivision of Ships other than those covered by paragraph

(e) of this Regulation, (i) The subdivision abaft the forepeak of ships 430 feet (or 131 meters) in length and upwards having a criterion numeral of 23 or less shall be governed by the factor A given by formula (I); of those having a criterion numeral of 123 or more by the factor B given by formula (II); and of those having a criterion numeral between 23 and 123 by the factor F obtained by linear interpolation between the factors A and B, using the formula:—

F = A-
(A - B)(C3 - 23)
.............................. (IV)
100

 

Where the factor F is less than 40 and it is shown to the satisfaction of the Administration to be impracticable to comply with the factor F in a machinery compartment of the ship, the subdivision of such compartment may be governed by an increased factor, which, however, shall not exceed 40.

(ii) The subdivision abaft the forepeak of ships less than 430 feet (or 131 meters) but not less than 260 feet (or 79 meters) in length having a criterion numeral equal to S, where—

S =

(L in feet) =

(L in meters)
9,382 - 20L
3,574 - 25L
34
13

shall be governed by the factor unity; of those having a criterion numeral of 123 or more by the factor B given by the formula (II); of those having a criterion numeral between S and 123 by the factor F obtained by linear interpolation between unity and the factor B using the formula:—

F = 1

............................. (VI)
(1-B) C3-S)
123- S

(iii) The subdivision abaft the forepeak of ships less than 430 feet (or 131 meters) but not less than 260 feet (or 79 meters) in length and having a criterion numeral less than S, and of all ships less than 260 feet (or 79 meters) in length shall be governed by the factor unity, unless, in either case, it is shown to the satisfaction of the Administration to be impracticable to comply with this factor in any part of the ship, in which case the Administration may allow such relaxation as may appear to be justified, having regard to all the circumstances.

(iv) The provisions of sub-paragraph (d) (iii) shall apply also to ships of whatever length, which are to be certified to carry a number of passengers exceeding 12 but not exceeding—

L = (in feet)

or 50, whichever is the less
7,000

650

(e) Special Standards of Subdivision for Ships which are permitted under Regulation 22 of Chapter 111 to carry a number of persons on board in excess of (he lifeboat capacity provided and are required under paragraph (d) of Regulation 1 in this Chapter to comply with special provisions.

(i) (a) In this case of ships primarily engaged in the carriage of passengers, the subdivision abaft the forepeak shall be governed by a factor of .50 or by the factor determined according to paragraphs (c) and (d) of this Regulation if less than .50.

(b) In the case of such ships less than 300 feet (or 91.5 meters) in length, if the administration is satisfied that compliance with such factor would be impracticable in a compartment, it may allow the length of that compartment to be governed by a higher factor provided the factor used is the lowest that is practicable and reasonable in the circumstances.

(ii) If, in the case of any ship whether less than 300 feet (or 91.5 meters) or not, the necessity of carrying appreciable quantities of cargo makes it impracticable to require the subdivision abaft the forepeak to be governed by a factor not exceeding .50 the standard of subdivision to be applied shall be determined in accordance with the following sub-paragraphs (a) to (e), subject to the condition that where the Administration is satisfied that insistence on strict compliance in any respect would be unreasonable, it may allow such alternative arrangement of such watertight bulkheads as appears to be justified on merits and will not diminish the general effectiveness of the subdivision.

(a) The provisions of paragraph (c) of this Regulation relating to the criterion numeral shall apply with the exception that in calculating the value of Pi for berthed passengers K is to have the value defined in paragraph (c) of this Regulation or 125 cubic feet (or 3.55 cubic meters), whichever is the greater, and for unberthed passengers K is to have the value 125 cubic feet (or 3.55 cubic meters.

(b) The factor B in paragraph (b) of this Regulation shall be replaced by the factor BB determined by the following formula:-


L in feet

+ .20
(L = 55 and upwards)

L—33

F = A -
(A - BB)(C3 - 23)

100

except that if the factor F so obtained is less than .50 the factor to be used shall be either .50 or the factor calculated according to the provisions of paragraph (d) (i) of this Regulation, whichever is the smaller.

(d) The subdivision abaft the forepeak of ships less than 430 feet (or 131 meters) but not less than ISO feet (or 55 meters) in length having a criterion numeral equal to Si where—


 
S1 =
1,950 - 4L
(L in feet)

100
 

 


 
S1 =
3,712 - 25L

shall be governed by the factor unity; of those having a criterion numeral of 123 or more by the factor BB given by the formula in sub-paragraph (ii) (b) of this paragraph; of those having a criterion numeral between Si and 123 by the factor F obtained by linear interpolation between unity and the factor BB, using the formula:—


 
F = 1
(1 - BB)(C3 - S1)

123 - S1


except that in either of the two latter cases if the factor so obtained is less than .50 the subdivision may be governed by a factor not exceeding .50.

(e) The subdivision abaft the forepeak of ships less than 430 feet (of 131 meters) but not less than 180 feet (or 55 meters) in length and having a criterion numeral less than Si, and of all ships less than 180 feet (or 55 meters) in length shall be governed by the factor unity, unless it is shown to the satisfaction of the Administration to be impracticable to comply with this factor in particular compartments, in which event the Administration may allow such relaxations in respect of those compartments as appear to be justified, having regard to all the circumstances, provided that the aftermost compartment and as many as possible of the forward compartments (between the forepeak and the after end of the machinery space) shall be kept within the floodable length.

REGULATION 6

SPECIAL RULES CONCERNING SUBDIVISION

(a) Where in a portion or portions of a ship the watertight bulkheads are carried to a higher deck than in the remainder of the ship, and it is desired to take advantage of this higher extension of the bulkheads in calculating the floodable length, separate margin lines may be used for each such portion of the ship provided that—

(i) the sides of the ship are extended throughout the ship's length to the deck corresponding to the upper margin line and all openings in the shell plating below this deck throughout the length of the ship are treated as being below a margin line, for the purposes of Regulation 13; and

(ii) the two compartments adjacent to the "step" in the bulkhead deck are each within the permissible length corresponding to their respective margin lines and, in addition, their combined length does not exceed twice the permissible length based on the lower margin line.

(b) (i) A compartment may exceed the permissible length determined by the rules of Regulation 5 provided the combined length of each pair of adjacent compartments to which the compartment in question is common does not exceed either the floodable length or twice the permissible length, whichever is the less.

(ii) If one of the two adjacent compartments is situated inside the machinery space, and the second is situated outside the machinery space, and the average permeability of the portion of the ship in which the second is situated differs from that of the machinery space, the combined length of the two compartments shall be adjusted to mean average permeability of the two portions of the ship in which the compartments are situated.

(iii) Where the two adjacent compartments have different factors of sub-division, the combined length of the two compartments shall be determined proportionately.

(c) In ships 430 feet (or 131 meters) in length and upwards, one of the main transverse bulkheads abaft the forepeak shall be fitted at a distance from the forward perpendicular which is not greater than the permissible length.

(d) A main transverse bulkhead may be recessed provided that all parts of the recess lie inboard of vertical surfaces on both sides of the ship, situated at a distance from the shell plating equal to one-fifth the breadth of the ship, as defined in Regulation 2, and measured at right angles to the centre line at the level of the deepest subdivision load line.

Any part of a recess which lies outside these limits shall be dealt with as a step in accordance with the following paragraph.

(e) A main transverse bulkhead may be stepped provided that it meets one of the following conditions:—

(i) The combined length of the two compartments, separated by the bulkhead in question, does not exceed 90 per cent, of the floodable length or twice the permissible length, except that in ships having a factor of subdivision greater than 9, the combined length of the two compartments in question shall not exceed the permissible length.

(ii) Additional subdivision is provided in way of the step to maintain the same measure of safety as that secured by a plane bulkhead.

(iii) The compartment over which the step extends does not exceed the permissible length corresponding to a margin line taken 3 inches (or 76 millimeters) below the step.

(f) Where a main transverse bulkhead is recessed or stepped, an equivalent plane bulkhead shall be used in determining the subdivision.

(g)) If the distance between two adjacent main transverse bulkheads, or their equivalent plane bulkheads, or the distance between the transverse planes passing through the nearest stepped portions of the bulkheads, is less than 10 feet (or 3.05 meters) plus 3 per cent, of the length of the ship, or 35 feet (or 10.67 meters) whichever is the less, only one of these bulkheads shall be regarded as forming part of the subdivision of the ship in accordance with the provisions of Regulation 5.

(h) Where a main transverse watertight compartment contains local subdivision and it can be shown to the satisfaction of the Administration that, after any assumed side damage extending over a length of 10 feet (or 3.05) meters) plus 3 per cent, of the length of the ship, or 35 feet (or 10.67 meters) whichever is the less, the whole volume of the main compartment will not be flooded, a proportionate allowance may be made in the permissible length otherwise required for such compartment. In such a case the volume of effective buoyancy assumed on the undamaged side shall not be greater than that assumed on the damaged side.

REGULATION 7

STABILITY OF SHIPS IN DAMAGED CONDITION

(a) Sufficient intact stability shall be provided in all service conditions so as to enable the ship to withstand the final stage of flooding of any one main compartment which is required to be within the floodable length.

Where two adjacent main compartments are separated by a bulkhead which is stepped under the conditions of subparagraph (e) (i) of Regulation 6, the intact stability shall be adequate to withstand the flooding of those two adjacent main compartments.

Where the required factor of subdivision is 50 or less the intact stability shall be adequate to withstand the flooding of any two adjacent main compartments.

(b) (i) The requirements of paragraph (a) of this Regulation shall be determined by calculations which are in accordance with paragraphs (c), (d) and (f), following, and which take into consideration the proportions and design characteristics of the ship and the arrangement and configuration of the damaged compartments. In making these calculations the ship is to be assumed in the worst anticipated service condition as regards stability.

(ii) Where it is proposed to fit decks, inner skins or longitudinal bulkheads of sufficient tightness to seriously restrict the flow of water, the Administration shall be satisfied that proper consideration is given to such restrictions in the calculations.

(c) For the purpose of making damage stability calculations the volume and surface permeabilities shall be as follows:

Spaces Permeability
Occupied by Cargo, Coal or Stores 60
Occupied by Accommodations 95
Occupied by Machinery 85
Intended for Liquids 0 or 95*
* Whichever results in the more severe requirements.

(d) Minimum assumed extent of damage shall be as follows:

(i) Longitudinal extent: 10 ft. (or 3.05 meters) plus 3 per cent, of the length of the ship, or 35 feet (or 10.67 meters) whichever is the less.

(ii) Transverse extent (measured inboard from the ship's side, at right angles to the centre line at the level of the deepest subdivision load line); a distance of one-fifth of the breadth of the ship, as defined in Regulation 2.

(iii) Vertical extent: From top of double bottom up to the margin line.

(iv) If any damage of lesser extent than that indicated in the foregoing sub-paragraphs (i), (ii) and (iii), would result in a more severe condition regarding heel or loss of metacentric height such damage shall be assumed in the calculations.

(e) Unsymmetrical flooding is to be kept to a minimum consistent with efficient arrangements. Where special cross-flooding fittings are provided these, together with the maximum heel before equalization, shall be acceptable to the Administration. Suitable information concerning the use of such fittings shall be supplied to the master of the ship.

(f) The final conditions of the ship after damage and after equalization measures have been taken shall be as follows:

(i) In the case of symmetrical flooding the risidual metacentric height shall be positive, except that, in special cases, the Administration may accept a negative metacentric height (upright) provided the resulting heel is not more than seven degrees.

(ii) In the case of unsymmetrical flooding the total heel shall not exceed seven degrees, except that, in special cases, the Administration may allow additional heel due to the unsymmetrical moment, but in no case shall the final heel exceed fifteen degrees.

(iii) In no case shall the margin line be submerged in the final stage of flooding. If it is considered that the margin line may become submerged during an intermediate stage of flooding, the Administration may require such investigations and arrangements as it shall consider necessary for the safety of the ship.

(g) The master of the ship shall be supplied with the data necessary to maintain sufficient intact stability under service conditions to enable the ship to withstand the critical damage. In the case of ships requiring cross-flooding the master of the ship shall be informed of the conditions of stability on which the calculations of heel are based and be warned that excessive heeling might result should the ship sustain damage when in a less favorable condition,

(h) (i) No relaxation from the requirements for damage stability may be considered by an Administration unless it is shown that the intact metacentric height in any service condition necessary to meet these requirements is excessive for the service intended.

(ii) Relaxations from the requirements for damage stability shall be permitted only in exceptional cases and subject to the condition that the Administration is to be satisfied that the proportions, arrangements and other characteristics of the ship are the most favorable to stability after damage which can practically and reasonably be adopted in the particular circumstances.

REGULATION 8

PEAK AND MACHINERY SPACE BULKHEADS, SHAFT TUNNELS, UC.

(a) (i) A ship shall have a forepeak or collision bulkhead, which shall be watertight up to the bulkhead deck. This bulkhead shall be fitted not less than 5 per cent, of the length of the ship, and not more than 10 feet (or 3.05 meters) plus 5 per cent, of the length of the ship from the forward perpendicular.

(ii) If the ship has a long forward superstructure, the forepeak bulkhead shall be extended weather tight to the deck next above the bulkhead deck. The extension need not be fitted directly over the bulkhead below, provided it is at least 5 per cent, of the length of the ship from the forward perpendicular, and the part of the bulkhead deck which forms the step is made effectively weather tight.

REGULATION 9

DOUBLE BOTTOMS

(a) A double bottom should be fitted extending from the forepeak bulkhead to the after peak bulkhead as far as this is practicable and compatible with the design and proper working of the ship.

(i) In ships 200 feet (or 61 meters) and under 249 feet (or 76 meters) in length a double bottom shall be fitted at least from the machinery space to the forepeak bulkhead, or as near thereto as practicable.

(ii) In ships 249 feet (or 76 meters) and under 330 feet (or 100 meters) in length a double bottom shall be fitted at least outside the machinery space, and shall extend to the fore and after peak bulkheads, or as near thereto as practicable.

(iii) In ships 330 feet (or 100 meters) in length and upwards a double bottom shall be fitted amidships, and shall extend to the fore and after peak bulkheads, or as near thereto as practicable.

(b) Where a double bottom is required to be fitted the inner bottom shall be continued out to the ship's sides in such a manner as to protect the bottom to the turn of the bilge. Such protection will be deemed satisfactory if the line of intersection of the outer edge of the margin plate with the bilge plating is not lower at any part than a horizontal plane passing through the point or" intersection with the frame line amidships of a transverse diagonal line inclined at 25 degrees to the base line and cutting it at a point one-half the ship's moulded breadth from the middle line.

(c) Small wells constructed in the double bottom in connection with drainage arrangements of holds, &c, shall not extend downwards more than necessary, nor shall they be less than 18 inches (or 457 millimeters) from the outer bottom or from the inner edge of the margin plate. A well extending to the outer bottom is, however, permitted at the after end of the shaft tunnel of screw ships. Other wells (e.g., for lubricating oil under main engines) may be permitted by the Administration, if satisfied that the arrangements give protection equivalent to that afforded by a double bottom complying with this Regulation.

(d) A double bottom need not be fitted in way of watertight compartments of moderate si2e exclusively for the carriage of liquids, provided the safety of the ship, in the event of bottom or side damage, is not, in the opinion of the Administration, thereby impaired.

(e) In the case of ships to which the provisions of paragraph (d) of Regulation 1 of this Chapter apply and which are engaged on regular service within ,the limits of a short international voyage as defined in paragraph (a) of Regulation 2 of Chapter III, the Administration may permit a double bottom to be dispensed "with in any part of the ship which is subdivided by a factor not exceeding 50, if satisfied that the fitting of a double bottom in that part would not be compatible with the design and proper working of the ship.

REGULATION 10

ASSIGNING, MARKING AND RECORDING OF SUBDIVISION LOAD LINES

(a) In order that the required degree of subdivision shall be maintained a load line corresponding to the approved subdivision draught shall be assigned and marked on the ship's sides. A ship having spaces which are specially adapted for the accommodation of passengers and the carriage of cargo alternatively may, if the owners desire, have one or more additional load lines assigned and marked to correspond with the subdivision draughts which the Administration may approve for the alternative service conditions.

(b) The subdivision load lines assigned and marked shall be recorded in the Safety Certificate, and shall be distinguished by the notation C.I for the principal passenger condition, and C.2, C.3, &c, for the alternative conditions.

(c) The freeboard corresponding to each of these load lines shall be measured at the same position and from the same deck line as the freeboards determined in accordance with the International Convention respecting Load Lines, 1930.

(d) The freeboard corresponding to each approved subdivision load line and the conditions of service for which it is approved, shall be clearly indicated on the Safety Certificate.

(e) In no case shall any subdivision load line mark be placed above the deepest load line in salt water as determined by the strength of the ship and/or the International Convention respecting Load Lines. 1930.

(f) Whatever may be the position of the subdivision load line marks, a ship shall in no case be loaded so as to submerge the load line mark appropriate to the season and locality as determined in accordance with the International Convention respecting Load Lines, 1930.

(g) A ship shall in no case be so loaded that when she is in salt water the subdivision load line mark appropriate to the particular voyage and condition of service is submerged.

REGULATION 11

CONSTRUCTION AND INITIAL TESTING OF WATERTIGHT BULKHEADS, &C.

(a) Watertight subdivision bulkheads, whether transverse or longitudinal, shall be constructed in such a manner that they shall be capable of supporting, with a proper margin of resistance, the pressure due to a head of water up to the margin line in way of each bulkhead. The construction of these bulkheads shall be to the satisfaction of the Administration.

(b) (i) Steps and recesses in bulkheads shall be watertight and as strong as the bulkhead at the place where each occurs.

(ii) Where frames or beams pass through a watertight deck or bulkhead, such deck or bulkhead shall be made structurally watertight without the use of wood or cement.

(c) Testing main compartments by filling them with water is not compulsory. A complete examination of the bulkheads shall be made by a surveyor; and, in addition, a hose test shall be made in all cases.

(d) The forepeak, double bottoms (including duct keels) and inner skins shall be tested with water to a head up to the margin line.

(e) Tanks which are intended to hold liquids, and which form part of the subdivision of the ship, shall be tested for tightness with water to a head up to the deepest subdivision load line or to a head corresponding' to two-thirds of the depth from the top of keel to the margin line in way of the tanks, whichever is the greater; provided that in no case shall the test head be less than 3 feet (or 0.92 meters) above the top of the tank.

(f) The tests referred to in paragraphs (d) and (e) are for the purpose of ensuring that the subdivision structural arrangement are watertight and are not to be regarded as a test of the fitness of any compartment for the storage of oil fuel or for other special purposes for which a test of a superior character may be required depending on the height to which the liquid has access in the tank or its connections.

REGULATION 12

OPENINGS IN WATERTIGHT BULKHEADS

(a) The number of openings in watertight bulkheads shall be reduced to the minimum compatible with the design and proper working of the ship; satisfactory means shall be provided for closing these openings.

(b) (i) Where pipes, scuppers, electric cables, &c, are carried through watertight subdivision bulkheads, arrangements shall be made to ensure the integrity of the water tightness of the bulkheads.

(ii) Valves and cocks not forming part of a piping system shall not be permitted in watertight subdivision bulkheads.

(c) (i) No doors, manholes, or access openings are permitted

(a) in the collision bulkhead below the margin line.

(b) in watertight transverse bulkheads dividing a cargo space from an adjoining cargo space or from a permanent reserve bunker, except as provided in paragraph (g) of this Regulation.

(ii) Except as provided in sub-paragraph (c) (iii) below, the collision bulkhead may be pierced below the margin line by not more than one pipe for dealing with fluid in the forepeak tank, provided that the pipe is fitted with a screw down valve capable of being operated from above the bulkhead deck, the valve chest being secured inside the forepeak to the collision bulkhead.

(iii) If the forepeak is divided to hold two different kinds of liquids, the Administration may allow the collision bulkhead to be pierced below the margin line by two pipes, each of which is fitted as required by the preceding clause, provided the Administration is satisfied that there is no practical alternative to the fitting of such second pipe and that, having regard to the additional subdivision provided in the forepeak, the safety of the ship is maintained.

(d) (i) Watertight doors fitted in bulkheads between permanent and reserve bunkers, shall be always accessible, except as provided in subparagraph (i) (ii) for between deck bunker doors.

(ii) Satisfactory arrangements shall be made by means of screens or otherwise, to prevent the coal from interfering with the closing of watertight bunker doors.

(e) Within the machinery space and apart from bunker and shaft tunnel doors, not more than one door may be fitted in each main transverse bulkhead for intercommunication. These doors shall be of the sliding type and shall be located so as to have the sills as high as practicable. The hand gear for operating these doors from above the bulkhead deck shall be situated outside the machinery space if this is consistent with a satisfactory arrangement of the necessary gearing.

(f) (i) The only types of watertight doors permissible are hinged doors, sliding doors, and doors of other equivalent patterns, excluding plate doors secured only by bolts and doors required to be closed by dropping or by the action of a dropping weight.

(ii) A hinged door shall be fitted with catches workable from each side of the bulkhead.

(iii) A sliding door may nave a horizontal or vertical motion. If required to be hand operated only, the gearing shall be operated with an all round crank motion, both at the door and at an accessible position above the bulkhead deck.

(iv) If a door is required to be power operated from a central control, the gearing shall be so arranged that the door can be operated by power also at the door itself. The arrangement shall be such that the door will close automatically if opened by the local control after being closed from the central control and also such that any door can be kept closed by local arrangements which will prevent that door from being opened from the central control. Local control handles in connection with the power gear shall be provided at each side of the bulkhead and shall be so arranged as to enable persons passing through the doorway to hold both handles in the open position. Such power operated doors shall be provided with hand gear, workable both at the door itself and from an accessible position above the bulkhead deck. At the latter position the hand gear shall be operated with an all round crank motion. Provision shall be made to give warning by sound signal when the door is about to be closed; the signal shall precede the movement of the door by a safe interval.

(v) In all classes of doors indicators shall be fitted at all operating stations other than at the door itself, showing whether the door is opened or closed.

(g) (i) Hinged watertight doors in passenger, crew, and working spaces are only permitted above a deck the underside of which, at its lowest point at side, is at least 7 feet (or 2.13 meters) above the deepest subdivision load line, and they are not permitted in those spaces below such deck.

(ii) Hinged watertight doors of satisfactory construction may be fitted in bulkheads dividing cargo between deck spaces, at the highest level consistent with practicability. The outboard vertical edges of such doors shall be situated at a distance from the shell plating which is not less than one-fifth the breadth of the ship, as defined in Regulation 2, such distance being measured at right angles to the centre line of the ship at the level of the deepest sub-division load line. These doors shall be closed before the voyage commences and shall be kept closed during navigation, and the time of opening such doors in port and of closing them before the ship leaves port shall be entered in such log books as may be prescribed by the Administration. Where it is proposed to fit such doors, the number and arrangements shall receive the special consideration of the Administration, and a statement shall be required from the owners certifying as to the absolute necessity of such doors.

(h) All other watertight doors shall be sliding doors.

(i) (i) When any watertight doors which may be sometimes opened at sea, excluding those at the entrances of tunnels, are fitted in the main transverse watertight bulkheads at such a height that their sills are below the deepest subdivision load line, the following rules shall apply:—

(I) When the number of such doors exceeds 5 all the watertight sliding door shall be power operated and shall be capable of being simultaneously closed from a station situated on the bridge.

(II) When the number of such doors does not exceed 5—

(a) if the criterion numeral does not exceed 30 all the watertight sliding doors may be operated by hand only;

(b) if the criterion numeral exceeds 30 all the watertight sliding doors shall be operated by power;

(c) in any ship, of whatever criterion numeral, if there is only one watertight door apart from the tunnel door, and it is in the machinery space the Administration may allow these two doors to be operated by hand only.

(ii) If watertight doors which have sometimes to be open at sea for the purpose of trimming coal are fitted between bunkers in the between-decks below the bulkhead deck, these doors shall be operated by power. The opening and dosing of these doors shall be recorded in such log book as may be prescribed by the Administration.

(iii) When trunk ways in connection with refrigerated cargo are carried through more than one main transverse watertight bulkhead and the sills of the openings are less than 7 feet (or 2.13 meters) above the deepest subdivision load line, the watertight doors at such openings shall be operated by power.

(j) Portable plates on bulkheads shall not be permitted except in machinery spaces. Such plates shall always be in place before the ship leaves port, and shall not be removed during navigation except in case of urgent necessity. The necessary precautions' shall be taken in replacing them to ensure that the joints shall be watertight.

(k) All watertight doors shall be kept closed during navigation except when necessarily opened for the working of the ship, and shall always be ready to be immediately closed.

(l) (i) Where trunk ways or tunnels for access from crew's accommodation to the stokehold, for piping, or for any other purpose are carried through main transverse watertight bulkheads, they shall be watertight and in accordance with the requirements of Regulation 15. The access to at least one end of each such tunnel or trunk way, if used as a passage at sea, shall be through a trunk extending watertight to a height sufficient to permit access above the margin line. The access to the other end of the trunk way or tunnel may be through a watertight door of the type required by its location in the ship. Such trunk ways or tunnels shall not extend through the first subdivision bulkhead abaft the collision bulkhead.

(ii) Where it is proposed to fit tunnels or trunk ways for forced draft, piercing main transverse watertight bulkheads, these shall receive the special consideration of the Administration.

REGULATION 13

OPENINGS IN THE SHELL PLATING BELOW THE MARGIN LINE

(a) The number of openings in the shell plating shall be reduced to the minimum compatible with the design and proper working of the ship.

(c) (i) If in a between decks, the sills of any side scuttles are below a line drawn parallel to the bulkhead deck at side and having its lowest point 2 l/2 per cent, of the breadth of the ship above the deepest subdivision load line, all side scuttles in that between deck shall be of a non-opening type.

(ii) All side scuttles the sills of which are below the margin line, other than those required to be of a non-opening type by sub-paragraph (c) (i), shall be of such construction as will effectively prevent any person opening them without the consent of the master of the ship.

(iii) (a) If in a between-decks, the sills of any of the side scuttles referred to in sub-paragraph (c) (ii) are below a line drawn parallel to the bulkhead deck at side and having its lowest point 4 feet (or 1.37 meters) plus 2 1/2 per cent of the breadth of the ship above the water when the ship departs from any port, all the side scuttles in that between decks shall be closed watertight and locked before the ship leaves port, and they shall not be opened before the ship arrives at the next port. In the application of this sub-paragraph the appropriate allowance for fresh water may be made when applicable.

(b) The time of opening such side scuttles in port and of closing and locking them before the ship leaves port shall be entered in such log book as may be prescribed by the Administration.

(c) For any ship that has one or more side scuttles so placed that the requirements of the first clause of this sub-paragraph would apply when she was floating at her deepest subdivision load line, the Administration may indicate the limiting mean draught at which these side scuttles will have their sills above the line drawn parallel to the bulkhead deck at side, and having its lowest point 4 feet (or 1.37 meters) plus 2l/s. per cent, of the breadth of the ship above the waterline corresponding to the limiting mean draught, and at which it will therefore be permissible to depart from port without previously closing and locking them and to open them at sea on the responsibility of the master during the voyage to the next port. In tropical zones as defined in the International Convention respecting Load Lines, 1930, this limiting draught may be increased by 1 foot (or 0.305 meters).

(d) Efficient hinged inside deadlights arranged so that they can be easily and effectively closed and secured watertight shall be fitted to all side scuttles, except that abaft one-eight of the ship's length from the forward perpendicular and above a line drawn parallel to the bulkhead deck at side and having its lowest point at a height of 12 feet (or 3.66 meters) plus 2l/z per cent, of the breadth of the ship above the deepest subdivision load line, the deadlights may be portable in passenger accommodation other than that for steerage passengers, unless the deadlights are required by the International Convention respecting Load Lines, 1930, to be permanently attached in their proper positions. Such portable deadlights shall be stowed adjacent to the side-scuttles they serve.

(e) Side scuttles and their deadlights, which will not be accessible during navigation, shall be closed and secured before the ship leaves port.

(f) (i) No side-scuttles shall be fitted in any spaces which are appropriated exclusively to the carriage of cargo or coal.

(ii) Side scuttles may, however, be fitted in spaces appropriated alternatively to the carriage of cargo or passengers, but they shall be of such construction as will effectively prevent any person opening them or their deadlights without the consent of the master of the ship

(iii) If cargo is carried in such spaces, the side-scuttles and their deadlights shall be closed watertight and locked before the cargo is shipped and such closing and locking shall be recorded in such logbook as may be prescribed by the Administration.

(g) Automatic ventilating side-scuttles shall not be fitted in the shell plating below the margin line without the special sanction of the Administration.

(h) The number of scuppers, sanitary discharges and other similar openings in the shell plating shall be reduced to the minimum either by making each discharge serve for as many as possible of the sanitary and other pipes, or in any other satisfactory manner.

(ii) (a) Except as provided in sub-paragraph (i) (iii), each separate discharge led through the shell plating from spaces below the margin line shall be provided either with one automatic non-return valve fitted with a positive means of closing it from above the bulkhead deck, or, alternatively, with two automatic non-return valves without such means, the upper of which is so situated above the deepest subdivision load line as to be always accessible for examination under service conditions, and is of a type which is normally closed.

(b) Where a valve with positive means of closing is fitted, the operating position above the bulkhead deck shall always be readily accessible, and means shall be provided for indicating whether the valve is open or closed.

(iii) Main and auxiliary sea inlets and discharges in connection with machinery shall be fitted with readily accessible cocks or valves between the pipes and shell plating or between the pipes and fabricated boxes attached to the shell plating.

(j) (i) Gangway, cargo and coaling ports fitted below the margin line shall be of sufficient strength. They shall be effectively closed and secured watertight before the ship leaves port, and shall be kept closed during navigation.

(ii) Such ports shall be in no case fitted so as to have their lowest point below the deepest subdivision load-line.

(k) (i) The inboard opening of each ash-shoot, rubbish-shoot, &c, shall be fitted with an efficient cover.

(ii) If the inboard opening is situated below the margin line, the cover shall be watertight, and in addition an automatic non-return valve shall be fitted in the shoot in an easily accessible position above the deepest load-line. When the shoot is not in use both the cover and the valve shall be kept close and secured.

REGULATION 14

CONSTRUCTION AND INITIAL TESTS OF WATERTIGHT DOORS, SIDE SCUTTLES, &C.

(a) (i) The design, materials and construction of all watertight doors, side scuttles, gangway, cargo and coaling ports, valves, pipes, ash-shoots, and rubbish-shoots referred to in these Regulations shall be to the satisfaction of the Administration.

(iii) Watertight doors giving direct access to any space containing bunker coal shall, together with the frames, be made of cast or wrought steel.

(iv) Cocks or valves of more than 3 inches bore (for 76 millimeters) for main and auxiliary sea inlets and discharges in connection with machinery shall be of steel or bronze as applicable, or other approved ductile material.

(v) Ordinary cast iron shall not be used for the other cocks and valves of any size, which are fitted to the shell plating below the bulkhead deck or which affect the subdivision arrangements of the ship.

(b) Each watertight door shall be tested by water pressure to a head up to the margin line. The test shall be made before the ship is put in service, either before or after the door is fitted.

REGULATION 15

CONSTRUCTION AND INITIAL TESTS OF WATERTIGHT DECKS, TRUNKS, &C.

(a) Watertight decks, trunks, tunnels, duct keels and ventilators shall be of the same strength as watertight bulkheads at corresponding levels. The means used for making them watertight, and the arrangements adopted for closing openings in them, shall be to the satisfaction of the Administration. Watertight ventilators and trunks shall be carried at least up to the bulkhead deck.

(b) After completion, a hose or flooding test shall be applied to watertight decks and a hose test to watertight trunks, tunnels and ventilators.

REGULATION 16

SIDE AND OTHER OPENINGS, &C, ABOVE THE MARGIN LINE

(a) Side scuttles, gangway, cargo and coaling ports, and other means for closing openings in the shell plating above the margin line shall be of efficient design and construction and of sufficient strength having regard to the spaces in which they are fitted and their positions relative to the deepest subdivision load line.

(b) The bulkhead deck or a deck above it shall be weather tight in the sense that in ordinary sea conditions water will not penetrate in a downward direction. All openings in the exposed weather deck shall have coatings of ample height and strength and shall be provided with efficient means for expeditiously closing them weather tight.

(c) Freeing ports and/or scuppers shall be fitted as necessary for rapidly clearing the weather deck of water under all weather conditions.

REGULATION 17

PUMPING ARRANGEMENTS

(a) Ships shall be provided with an efficient pumping plant, capable of pumping from and draining any watertight compartment under all practicable conditions after a casualty whether the ship is upright or listed. For this purpose wing suctions will generally be necessary except in narrow compartments at the ends of the ship, where one suction may be sufficient. In compartments of unusual form, additional suctions may be required. Arrangements shall be made whereby water in the compartment may find its way to the suction pipes. Efficient means shall be provided for draining water from insulated holds.

(b) (i) Except as provided elsewhere in this Regulation, ships shall have at least three power pumps connected to the bilge main, one of which may be attached to the propelling unit. Where the criterion numeral is 30 or more, one additional independent power pump shall be provided. In ships less than 300 feet (or 91.5 meters) in length and having a criterion numeral less than 30, two efficient hand-pumps of the crank type, fitted one forward and one aft, may be substituted for one of the independent power pumps.

(ii) The requirements are summarized in the following table:—

  Less than 300 feet (or 91.5 meters) 300 feet (or 91.5 meters) and over

(iii) Sanitary, ballast and general service pumps may be accepted as independent power bilge pumps if fitted with the necessary connections to the bilge pumping system.

(c) Where practicable, the power bilge pumps shall be placed in separate watertight compartments so arranged or situated that these compartments will not readily be flooded by the same damage. If the engines and boilers are in two or more watertight compartments, the pumps available for bilge service shall be distributed "through these compartments as far as is possible.

(d) On ships 300 feet (or 91.5 meters) or more in length or having a criterion numeral of 30 or more, the arrangements shall be such that at least one power pump will be available for use in all ordinary circumstances in which a ship may be flooded at sea. This requirement will be satisfied if—

(i) One of the required pumps is an emergency pump of a reliable submersible type having a source of power situated above the bulkhead deck, or

(ii)The pumps and their sources of power are so disposed throughout the length of the ship that under any condition of flooding which the ship is required to withstand, at least one pump in an undamaged compartment will be available.

(e) With the exception of pumps which may be provided for peak compartments only, each bilge pump, whether operated by hand or by power shall be arranged to draw water from any hold or machinery compartment in the ship.

(f) (i) Each independent power bilge pump shall be capable of giving a speed of water through the main bilge pipe of not less than 400 feet (or 122 meters) per minute. Independent power bilge pumps situated in machinery spaces shall have direct suctions from these spaces, except that not more than two such suctions shall be required in any one space. The Administration may require independent power bilge pumps situated in other spaces to have separate direct suctions. Direct suctions shall be suitably arranged and those in a machinery space shall be or a diameter not less than that of the bilge main.

(ii) In coal-burning ships there shall be provided in the stokehold, in addition to the other suctions required by this Regulation, a flexible suction hose of suitable diameter and sufficient length, capable of being connected to the suction side of an independent power pump.

(g) Main circulating pumps shall have direct suction connections, provided with non-return valves, to the lowest drainage level in the machinery space, and of a diameter at least two-thirds that of the main sea inlet. Where the fuel is, or may be, coal and there is no watertight bulkhead between the engines and the boilers, a direct discharge overboard shall be fitted from at least one circulating pump, or, alternatively, a by-pass may be fitted to the circulating discharge. The spindles of the sea inlet and direct suction valves shall extend well above the engine room platform.

(h) (i) All pipes from the pumps which are required for draining cargo or machinery spaces shall be entirely distinct from pipes which may be used for tilling or emptying spaces where water or jail is carried.

(ii) Lead pipes shall not be used in or under coal bunkers or oil fuel storage tanks, or in boiler or machinery spaces, including motor rooms in which oil settling tanks or oil fuel pumping units are situated.

(i) The Administration shall make rules relating to the diameters of the bilge main and branch pipes. The diameter of the bilge main may be determined approximately from the following formulæ;—

See Formula at Philippine Treaties, Volume I, Page 776.

(j) The arrangement of the bilge and ballast pumping system shall be such as to prevent the possibility of water passing from the sea and from water ballast spaces into the cargo and machinery spaces, or from one compartment to another. Special provision shall be made to prevent any deep tank having bilge and ballast connections being inadvertently run up from the sea when containing cargo, or pumped out through a bilge pipe when containing water ballast.

(k) Provision shall be made to prevent the compartment served by any bilge suction pipe being flooded, in the event of the pipe being severed or otherwise damaged by collision or grounding, in any other compartment. For this purpose, where the pipe is at any part situated nearer the side of the ship than one-fifth the breadth of the ship (measured at right angles in the centre line at the level of the deepest sub-division load line), or in a duct keel, a non-return valve shall be fitted to the pipe in the compartment containing the open end.

(l) All the distribution boxes, cocks, and valves in connection with the bilge pumping arrangements shall be in positions which are accessible at all limes under ordinary circumstances. They shall be so arranged that, in the event of flooding, one of the bilge pumps may be operative on any compartment. If there is only one system of pipes common to all the pumps, the necessary cocks or valves for controlling the bilge suctions must be workable from above the bulkhead deck. If, in addition to the main bilge pumping system an emergency bilge pumping system is provided, it shall be independent of the main system and so arranged that a pump is capable of operating on any compartment under flooding conditions.

REGULATION 18

STABILITY TESTS FOR PASSENGER SHIPS AND CARGO SHIPS

(a) Passenger ships and cargo ships shall be inclined upon their completion and the elements of their stability determined. The master shall be supplied with such information on this subject as is necessary to permit efficient handling of the ship, and a copy shall be furnished to the Administration concerned.

(b) The Administration may allow the inclining test of an individual ship to be dispensed with provided basic stability data are available from the inclining test of a sister ship and it is shown to the satisfaction of the Administration that reliable stability information for the exempted ship can be obtained from such data.

REGULATION 19

PERIODICAL OPERATION AND INSPECTION OF WATERTIGHT DOORS, &C.

(a) In new and existing ships drills for the operating of watertight doors, side scuttles, valves and closing mechanisms of scuppers, ash-shoots and rubbish-shoots, shall take place weekly. If ships in which the voyage exceeds one week in duration a complete drill shall be held before leaving port, and others thereafter at least once a week during the voyage, provided that all watertight power doors and hinged doors, in main transverse bulkheads, in use at sea, shall be operated daily.

(b) The watertight doors and all mechanisms and indicators connected therewith, all valves the closing of which is necessary to make a compartment watertight and all valves the operation of which is necessary for damage control cross connections shall be periodically inspected at sea, at least once a week.

REGULATION 20

ENTRIES IN LOG

(a) In new and existing ships hinged doors, portable plates, side scuttles, gangway, cargo and coaling ports and other openings, which are required by these Regulations to be kept closed during navigation, shall be closed before the ship leaves port. The time of closing and the time of opening (if permissible under these Regulations), shall be recorded in such log book as may be prescribed by the Administration.

(b) A record or all drills and inspections required by Regulation 19 shall be entered in the log book with an explicit record of any defects which may be disclosed.

PART C-ELECTRICAL INSTALLATIONS

(PART C APPLIES TO PASSENGER SHIPS ONLY)

REGULATION 21

GENERAL

(a) Electrical installations in ships shall be such that:—

(i) services essential for safety will be maintained under various emergency conditions; and

(ii) the safety of passengers, crew and ship from electrical hazards will be assured.

(b) Every ship, the electrical power of which constitutes the only means of maintaining the auxiliary services indispensable for the propulsion and the safety of the ship, shall be provided with at least two main generating sets. The power of these sets shall be such that it shall still be possible to ensure the functioning of the said services in the event of any one of these generating sets being stopped.

REGULATION 22

EMERGENCY SOURCE OF POWER

(a) There shall be above the bulkhead deck a self-contained emergency source of electrical power. It shall be situated outside the machinery casings. The power available shall be sufficient to supply all those services that are, in the opinion of the Administration, necessary for the safety of the passengers and the crew in an emergency, due regard being paid to such services as may have to be operated simultaneously. Special consideration shall be given to emergency lighting at every boat station on deck and over sides, in all alleyways, stairways and exits, in the machinery spaces and in the control stations as defined in Regulation 26, and to navigation lights if solely electric. The power shall be adequate for a period of 36 hours, except that, in the case of ships engaged regularly on voyages of short duration, the Administration may accept a lesser supply if satisfied, that the same standard of safety would be attained. The source of emergency power may be either—

(i) an accumulator (storage) battery capable of carrying the emergency load without recharging or excessive voltage drop; or

(ii) a generator driven by a suitable type of compression ignition engine with an independent fuel supply and with starting arrangements approved by the Administration. The fuel used shall have a flash point of not less than 110°F. (or 43.3°C).

(b) Arrangements shall be such that the emergency plant will function efficiently when the ship is inclined 22h° and/or when the trim of the ship is 10° from an even keel.

(c) (i) Where the emergency power is derived from an accumulator battery, arrangements shall be made to ensure that emergency lighting will automatically come into operation in the event of failure of the main lighting supply.

(ii) Where the emergency source of power is a generator, there shall be provided a temporary source of emergency power from an accumulator battery of sufficient capacity—

(a) to supply emergency lighting continuously for half-an-hour; and

(b) to close the watertight doors (if electrically operated) but not necessarily to close them all simultaneously.

The arrangements shall be such that the temporary source of emergency power will come into operation automatically in the event of failure of the main supply.

(iii) Provision shall be made for the periodic testing of automatic arrangements.

(d) Electrically operated steering gears shall be served by two sets of feeder cables from the main switchboard. Each feeder shall have adequate capacity for serving all motors which may operate simultaneously, and these feeders shall be separated throughout their length as widely as is practicable. Short circuit protection only shall be provided for these circuits and motors.

REGULATION 23

NUMBER OF DAVITS AND CAPACITY OF LIFEBOATS AND BUOYANT APPARATUS

(a) (i) A passenger ship shall be provided with sets of davits in accordance with its length as provided in Column A of the Table in Regulation 24 except that a number of sets of davits greater than the number of lifeboats necessary for the accommodation of all the persons on board shall not be required,

(ii) Each set of davits shall have a lifeboat attached. If these lifeboats do not provide sufficient accommodation for all persons on board, additional sets of davits with lifeboats attached shall be fitted if practicable. If the lifeboats attached to davits do not provide accommodation for all persons on board, additional lifeboats shall be carried under the lifeboats attached to davits so that accommodation for all persons is provided.

(iii) When in the opinion of the Administration it is impracticable or unreasonable to place on a ship the number of sets of davits required by Column A of the Table in Regulation 24, the Administration may authorize, under exceptional conditions, a smaller number of sets of davits as specified in Column B of the Table.

(b) (i) A passenger ship engaged on a short international voyage shall be provided with sets of davits in accordance with its length as specified in Column A of the Table in Regulation 24. Each set of davits shall have a lifeboat attached to it and these lifeboats shall provide at least the minimum capacity required by Column C of the Table or the capacity required provided accommodation for all persons on board if less. In the case of ships certified to carry a number of persons in excess of the lifeboat capacity specified in Column C, additional lifeboats under davits or approved buoyant apparatus shall be provided so that the total accommodation afforded by all the lifeboats, together with the buoyant apparatus, shall be sufficient for all on board. In addition there shall be buoyant apparatus for 10 per cent, of all on board.

(ii) When in the opinion of the Administration it is impracticable or unreasonable to place on a ship engaged on short international voyages the number of sets of davits required by Column A of the Table in Regulation 24, the Administration may authorize, under exceptional conditions, a smaller number of sets of davits, except that this number shall never be less than the minimum number fixed by Column B of the Table, and that the total capacity of the lifeboats on the ship will be at least up to the minimum capacity required by Column C or the capacity required to provide for all persons on board if less.

(c) Passenger ships shall carry two boats attached to davits-one on each side of the ship-for use in an emergency. These boats shall be of a type approved by the Administration and shall normally be not more than 26 feet (or 8 meters) in length. They may be counted for the purposes of Regulation 22, provided that they comply fully with the requirements of this Chapter for lifeboats. They shall be kept ready for immediate use while the ship is at sea. In ships in which the requirements of Regulation 26 (j) are met by means of appliances fitted to the sides of the lifeboats, such appliances shall not be required to be fitted to the two boats provided to meet the requirements of this Regulation.

REGULATION 24

(ii) Either forward of or abaft the white light mentioned in sub-section (i) a second white light similar in construction and character to that light. Vessels of less than 150 feet in length, and vessels engaged in towing, shall not be required to carry this second white light but may do so.

(iii) These two white lights shall be so placed in a line with and over the keel that one shall be at least 15 feet higher than the other and in such a position that the lower light shall be forward of the upper one. The horizontal distance between the two white lights shall be at least three times the vertical distance. The lower of these two white lights or, if only one is carried, then that light, shall be .placed at a height above the hull of not less than 20 feet, and, if the breadth of the vessel exceeds 20 feet, then at a height above the hull not less than such breadth, so however that the light need not be placed at a greater height above the hull than 40 feet. In all circumstances the light or lights, as the case may be, shall be so placed as to be clear of and above all other lights and obstructing superstructures.

(iv) On the starboard side a green light so constructed as to show an unbroken light over an arc of the horizon of 10 points ot the compass (112^ degrees), so fixed as to show the light from right ahead to 2 points (221 degrees) abaft the beam on the starboard side, and of such a character as to be visible at a distance of at least 2 miles.

(vi) The said green and red sidelights shall be fitted with inboard screens projecting at least 3 feet forward from the light, so as to prevent these lights from being seen across the bows.

(b) A seaplane under way on the water shall carry:

(i) In the forepart amidships where it can best be seen a bright white light, so constructed as to show an unbroken light over an arc of the horizon of 220 degrees of the compass, so fixed as to show the light 110 degrees on each side of the seaplane, namely, from right ahead to 20 degrees abaft the beam on either side, and of such a character as to be visible at a distance of at least 3 miles.

(ii) On the right or starboard wing tip a green light, so constructed as to show an unbroken light over an arc of the horizon of 110 degrees of the compass, so fixed as to show the light from right ahead to 20 degrees abaft the beam on the starboard side, and of such a character as to be visible at a distance of at least 2 miles.

(iii) On the left or port wing tip a red light, so constructed as to show an unbroken light over an arc of the horizon of 110 degrees of the compass, so fixed as to show the light from right ahead to 20 degrees abaft the beam on the port side, and of such a character as to be visible at a distance of at least 2 miles.

RULE 3

(a) A power-driven vessel when towing or pushing another vessel shall, in addition to her sidelights, carry two bright white lights in a vertical line one over the other, not less than 6 feet apart, and when towing more than one vessel shall carry an additional bright white light 6 feet above or below such lights, if the length of the tow, measuring from the stern of the towing vessel to the stern of the last vessel towed, exceeds 600 feet. Each of these lights shall be of the same construction and character and one of them shall be carried in the same position as the white light mentioned in Rule 2 (a) (i), except the additional light, which shall be carried at a height of not less than 14 feet above the hull. In a vessel with a single mast, such lights may be carried on the mast.

(b) The towing vessel shall also show either the stern light specified in Rule 10 or in lieu of that light a small white light abaft the funnel or after mast for the tow to steer by, but such light shall not be visible forward of the beam. The carriage of the white light specified in Rule 2 (a) (ii) is optional.

(c) A seaplane on the water, when towing one or more seaplanes or vessels, shall carry the lights prescribed in Rule 2 (b) (i), (ii), (iii); and, in addition, she shall carry a second white light of the same construction and character as the white light mentioned in Rule 2 (b) (i), and in a vertical line at least 6 feet above or below such light.

RULE 4

(a) A vessel which is not under command shall carry, where they can best be seen, and, if a power-driven vessel, in lieu of the lights required by Rule 2 (a) (i) and (ii), two red lights in a vertical line one over the other not less than 6 feet apart, and of such a character as to be visible all round the horizon at a distance of at least 2 miles. By day, she shall carry in a vertical line one over the not less than 6 feet apart, where they can best be seen, two black balls or shapes each not less than 2 feet in diameter.

(b) h seaplane on the water which, is not under command may carry, where they can best be seen, two red lights in a vertical line, one over the other, not less than 3 feet apart, and of such a character as to be visible all round the horizon at a distance of at least 2 miles, and may by day carry in a vertical line one over the other not less than 3 feet apart, where they can best be seen, two black balls or shapes, each not less than 2 feet in diameter.

(c) A vessel engaged in laying or in picking up a submarine cable or navigation mark, or a vessel engaged in surveying or underwater operations when from the nature of her work she is unable to get out of the way of approaching vessels, shall carry, in lieu of the lights specified in Rule 2 (a) (i) and (ii), three lights in a vertical line one over the other not less than 6 feet apart. The highest and lowest of these lights shall be red, and the middle light shall be white, and they shall be of such a character as to be visible all round the horizon at a distance of at least 2 miles. By day, she shall carry in a vertical line one over the other not less than 6 feet apart, where they can best be seen, three shapes each not less than 2 feet in diameter, of which the highest and lowest shall be globular in shape and red in color, and the middle one diamond in shape and white.

(d) The vessels and seaplanes referred to in this Rule, when not making way through the water shall not carry the colored sidelights, but when making way they shall carry them.

(e) The lights and shapes required to be shown by this.Rule are to be taken by other vessels and seaplanes as signals that the vessel or seaplane showing them is not under command and cannot therefore get out of the way.

(f) These signals are not signals of vessels in distress and requiring assistance. Such signals are contained in Rule 31.

RULE 5

(a) A sailing vessel under way and any vessel or seaplane being towed shall carry the same lights as are prescribed by Rule 2 for a power-driven vessel or a seaplane under way, respectively, with the exception of the white lights specified therein, which they shall never carry. They shall also carry stern lights as specified in Rule 10, provided that vessels towed, except the last vessel of a tow, may carry, in lieu of such stern light, a small white light as specified in Rule 3 (b).

(b) A vessel being pushed ahead shall carry, at the forward end, on the starboard side a green light and on the port side a red light, which shall have the same characteristics as the lights described in Rule 2 (a) (iv) and (v) and shall be screened as provided in Rule 2 (a) (vi), provided that any number of vessels pushed ahead in a group shall be lighted as one vessel.

RULE 6

(a) In small vessels, when it is not possible on account of bad weather or other sufficient cause to fix the green and red sidelights, these lights shall be kept at hand lighted and ready for immediate use, and shall, on the approach of or to other vessels, be exhibited on their respective sides in sufficient time to prevent collision, in such manner as to make them most visible, and so that the green light shall not be seen on the port side nor the red light on the starboard side, nor, if practicable, more than 2 points (22 degrees) abaft the beam on their respective sides.

(b) To make the use of these portable lights more certain and easy, the lanterns containing them shall each be painted outside with the color of the lights they respectively contain, and shall be provided with proper screens.

RULE 7

Power-driven vessels of less than 40 tons, vessels under oars or sails of less than 20 tons, and rowing boats, when under way shall not be required to carry the lights mentioned in Rule 2, but if they do not carry them they shall be provided with the following lights:

(a) Power-driven vessels of less than 40 tons, except as provided in section (b), shall carry:

(i) In the forepart of the vessel, where it can best be seen, and at a height above the gunwale of not less than 9 feet, a bright white light constructed and fixed as prescribed in Rule 2 (a) (i) and of such a character as to be visible at a distance of at least 3 miles.

(ii) Green and red sidelights constructed and fixed as prescribed in Rule 2 (a) (iv) and (v), and of such a character as to be visible at a distance of at least 1 mile, or a combined lantern showing a green light and a red light from right ahead to 2 points (22 1/2 degrees) abaft the beam on their respective sides. Such lantern shall be carried not less than 3 feet below the white light.

(b) Small power-driven boats, such as are carried by seagoing vessels, may carry the white light at a less height than 9 feet above the gunwale, but it shall be carried above the sidelights or the combined lantern mentioned in sub-section (a) (ii).

(c) Vessels of less than 20 tons, under oars or sails, except as provided in section (d), shall, if they do not carry the sidelights, carry where it can best be seen a lantern showing a green light on one side and a red light on the other, of such a character as to be visible at a distance of at least 1 mile, and so fixed that the green light shall not be seen on the port side, nor the red light on the starboard side. Where it is not possible to fix this light, it shall be kept ready for immediate use and shall be exhibited in sufficient time to prevent collision and so that the green light shall not be seen on the port side nor the red light on the starboard side.

(d) Small rowing boats, whether under oars or sail, shall only be required to have ready at hand an electric torch or a lighted lantern showing a white light, which shall be exhibited in sufficient time to prevent collision.

(e) The vessels and boats referred to in this Rule shall not be required to carry the lights or shapes prescribed in Rules 4 (a) and 11 (e).

RULE 8

(c) Between sunrise and sunset every vessel when at anchor shall carry in the forepart of the vessel, where it can best be seen, one black ball not less than 2 feet in diameter.

(d) A vessel engaged in laying or in picking up a submarine cable or navigation mark, or a vessel engaged in surveying or underwater operations, when at anchor, shall carry the lights or shapes prescribed in Rule 4 (c) in addition to those prescribed in the appropriate preceding sections of this Rule.

(e) A vessel aground shall carry by night the light or lights prescribed in sections (a) or (b) and the two red lights prescribed in Rule 4 (a). By day she shall carry, where they can best be seen, three black balls, each not less than 2 feet in diameter, placed in a vertical line one over the other, not less than 6 feet apart.

(f) A seaplane on the water under 150 feet in length, when at anchor, shall carry, where it can best be seen, a white light, visible all round the horizon at a distance of at least 2 miles.

(g) A seaplane on the water 150 feet or upwards in length, when at anchor, shall carry, where they can best be seen, a white light forward and a white light aft, both lights visible all round the horizon at a distance of at least 3 miles; and, in addition, if the seaplane is more than 150 feet in span, a white light on each side to indicate the maximum span, and visible, so far as practicable, all round the horizon at a distance of 1 mile.

(h) A seaplane aground shall carry an anchor light or lights as prescribed in sections (f) and (g), and in addition may carry two red lights in a vertical line, at least 3 feet apart, so placed as to be visible all round the horizon.

RULE 12

Every vessel or seaplane on the water may, if necessary in order to attract attention, in addition to the lights which she is by these Rules required to carry, show a flare-up light or use a detonating or other efficient sound signal that cannot be mistaken for any signal authorized elsewhere under these Rules.

RULE 13

(a) Nothing in these Rules shall interfere with the operation of any special rules made by the Government of any nation with respect to additional station and signal lights for ships of war, for vessels sailing under convoy, or for seaplanes on the water; or with the exhibition of recognition signals adopted by ship owners, which have been authorized by their respective Governments and duly registered and published.

(b) Whenever the Government concerned shall have determined that a naval or other military vessel or waterborne seaplane of special construction or purpose cannot comply fully with the provisions of any of these Rules with respect to the number, position, range or arc of visibility of lights or shapes, without interfering with the military function of the vessel or seaplane, such vessel or seaplane shall comply with such other provisions in regard to the number, position, range or arc of visibility of lights or shapes as her Government shall have determined to be the closest possible compliance with these Rules in respect of that vessel or seaplane.

RULE 14

A vessel proceeding under sail, when also being propelled by machinery, shall carry in the daytime forward, where it can best be seen, one black conical shape, point upwards, not less than 2 feet in diameter at its base.

RULE 15

(a) A power-driven vessel shall be provided with an efficient whistle, sounded by steam or by some substitute for steam, so placed that the sound may not be intercepted by any obstruction, and with an efficient fog-horn, to be sounded by mechanical means, and also with an efficient bell, A sailing vessel of 20 tons or upwards shall be provided with a similar fog-horn and bell.

(b) All signals prescribed by this Rule for vessels under way shall be given:

(i) by power-driven vessels on the whistle;

(ii) by sailing vessels on the fog-horn;

(iii) by vessels towed on the whistle or fog-horn.

(c) In fog, mist, falling snow, heavy rainstorms, or any other condition similarly restricting visibility, whether by day or night, the signals prescribed in this Rule shall be used as follows:

(i) A power-driven vessel making way through the water, shall sound at intervals of not more than 2 minutes a prolonged blast.

(ii) A power-driven vessel under way, but stopped and making no way through the water, shall sound at intervals of not more than 2 minutes two prolonged blasts, with an interval of about 1 second between them.

(iii) A sailing vessel under way shall sound, at intervals of not more than 1 minute, when on the starboard tack one blast, when on the port tack two blasts in succession, and when with the wind abaft the beam three blasts in succession.

(iv) A vessel when at anchor shall at intervals of not more than 1 minute ring the bell rapidly for about 5 seconds. In vessels of more than 350 feet in length the bell shall be sounded in the forepart of the vessel, and in addition there shall be sounded in the after part of the vessel, at intervals or not more than 1 minute for about 5 seconds, a gong or other instrument, the tone and sounding of which cannot be confused with that of the bell. Every vessel at anchor may in addition, in accordance with Rule 12, sound three blasts in succession, namely, one short, one prolonged, and one short blast, to give warning of her position and of the possibility of collision to an approaching vessel.

(v) A vessel when towing, a vessel engaged in laying or in picking up a submarine cable or navigation mark, and a vessel under way which is unable to get out of the way of an approaching .vessel through being not under command or unable to maneuver as required by these Rules shall, instead of the signals prescribed in subsections (i), (ii) and (iii) sound, at intervals of not more than 1 minute, three blasts in succession, namely, one prolonged blast followed by two short blasts.

(vi) A vessel, towed, or, if more than one vessel is towed, only the last vessel of the two, if manned, shall, at intervals of not more than 1 minute, sound four blasts in succession, namely, one prolonged blast followed by three short blasts. When practicable, this signal shall be made immediately after the signal made by the towing vessel.

(vii) A vessel aground shall give the signal prescribed in sub-section (iv) and shall, in addition, give three separate and distinct strokes on the bell immediately before and after each such signal.

(viii) A vessel of less than 20 tons, or rowing boat, or a seaplane on the water, shall not be obliged to give the above-mentioned signals, but if she does not, she shall make some other efficient sound signal at intervals of not more than 1 minute.

(ix) A vessel when fishing, if of 20 tons or upwards, shall at intervals of not more than 1 minute, sound at blast, such blast to be followed by ringing the bell; or she may sound, in lieu of these signals, a blast consisting of a series of several alternate notes of higher and lower pitch.

RULE 16

SPEED TO BE MODERATE IN FOG, &C.

(a) Every vessel, or seaplane when taxiing on the water, shall, in fog, mist, falling snow, heavy rainstorms or any other condition similarly restricting visibility, go at a moderate speed, having careful regard to the existing circumstances and conditions,

(b) A power-driven vessel hearing, apparently forward of her beam, the fog-signal of a vessel the position of which is not ascertained, shall, so far as the circumstances of the case admit, stop her engines, and then navigate with caution until danger of collision is over.

PART C—STEERING AND SAILING RULES

PRELIMINARY

1. In obeying and constructing these Rules, any action taken should be positive, in ample time, and with due regard to the observance of good seamanship.

2. Risk of collision can, when circumstances permit, be ascertained by carefully watching the compass bearing of an approaching vessel. If the bearing does not appreciably change, such risk should be deemed to exist.

3. Mariners should bear in mind that seaplanes in the act of landing or taking off, or operating under adverse weather conditions, may be unable , to change their intended action at the last moment.

RULE 17

When two sailing vessels are approaching one another; so as to involve risk of collision, one of them shall keep out of the way of the other, as follows:

(a) A vessel which is running free shall keep out of the way of a vessel which is close-hauled.

(b) A vessel which is close-hauled on the port tack shall keep out of the way of a vessel which is close-hauled on the starboard tack.

(c) When both are running free, with the wind on different sides, the vessel which has the wind on the port side shall keep out of the way of the other.

(d) When both are running free, with the wind on the same side, the vessel which is to windward shall keep out of the way of the vessel which is to leeward.

(e) A vessel which has the wind aft shall keep out of the way of the other vessel.

RULE 18

(a) When two power-driven vessels are meeting end on, or nearly end on, so as to involve risk of collision, each shall alter her course to starboard, so that each may pass on the port side of the other. This Rule only applies to cases where vessels are meeting end on, or nearly end on, in such a manner as to involve risk of collision, and does not apply to two vessels which must, if both keep on their respective courses, pass clear of each other. The only cases to which it does apply are when each of two vessels is end on, or nearly end on, to the other; in other words, to cases in which, by day, each vessel sees the masts of the other in a line, or nearly in a line, with her own; and by night, to cases in which each vessel is in such a position as to see both the sidelights of the other. It does not apply, by day, to cases in which a vessel sees another ahead crossing her own course; or, by night, to cases where the red light of one vessel is opposed to the red light of the other or where the green light of one vessel is opposed to the green light of the other or where a red light without a green light or a green light without a red light is seen ahead, or where both green and red lights are seen anywhere but ahead.

(b) For the purposes of this Rule and Rules 19 to 29 inclusive, except Rule 20 (b), a seaplane on the water shall be deemed to be a vessel and the expression "power-driven vessel" shall be construed accordingly.

RULE 19

When two power-driven vessels are crossing, so as to involve risk of collision, vessel which has the other on her own starboard side shall keep out of the way of the other.

RULE 20

(a) When a power-driven vessel and a sailing vessel are proceeding in such directions as to involve risk of collision, except as provided in Rules 24 and 26, the power-driven vessel shall keep out of the way of the sailing vessel.

(b) A seaplane on the water shall, in general, keep well clear of all vessels and avoid impeding their navigation. In circumstances, however, where risk of collision exists, she shall comply with these Rules.

RULE 21

Where by-any of these Rules one of two vessels is to keep out of the way, the other shall keep her course and speed. When, from any cause, the latter vessel finds herself so close that collision cannot be avoided by the action of the giving-way vessel alone, she also shall take such action as will best aid to avert collision (see Rules 27 and 29).

RULE 22

Every vessel which is directed by these Rules to keep out of the way of another vessel shall, if the circumstances of the case admit, avoid crossing ahead of the other.

RULE 23

Every power-driven vessel which is directed by these Rules to keep out of the way of another vessel shall, on approaching her, if necessary, slacken her speed or stop or reverse.

RULE 24

(a) Notwithstanding anything contained in these Rules, every vessel over-raking any other shall keep out of the way of the overtaken vessel.

(b) Every vessel coming up with another vessel from any direction more than 2 points (22 1/2 degrees) abaft her beam, i.e. in such a position, with reference to the vessel which is overtaking, that at night she would be unable to see either of that vessel's sidelights, shall be deemed to be an overtaking vessel and no subsequent alteration of the bearing between the two vessels shall make the overtaking vessel a crossing vessel within the meaning of these Rules, or relieve her of the duty of keeping clear of the overtaken vessel until she is finally past and clear.

(c) If the overtaking vessel cannot determine with certainty whether she is forward of or abaft this direction from the other vessel, she shall assume that she is an overtaking vessel and keep out of the way.

RULE 25

(a) In a narrow channel every power-driven vessel when proceeding along the course of the channel shall, when it is safe and practicable, keep to that side of the fairway or mid-channel which lies on the starboard side of such vessel.

(b) Whenever a power-driven vessel is nearing a bend in a channel where a power-driven vessel approaching from the other direction cannot be seen, such vessel, when she shall have arrived within one-half mile of the bend, shall give a signal by one prolonged blast of her whistle, which signal shall be answered by a similar blast given by any approaching power-driven vessel that may be within hearing around the bend. Regardless of whether an approaching vessel on the farther side of the bend is heard, such bend shall be rounded with alertness and caution.

RULE 26

All vessels not engaged in fishing shall, when under way, keep out of the way of any vessels fishing with nets or lines or trawls. This Rule shall not give to any vessel engaged in fishing the right of obstructing a fairway used by vessels other than fishing vessels.

RULE 27

In obeying and construing these Rules due regard shall be had to all dangers of navigation and collision, and to any special circumstances, including the limitations of the craft involved, which may render a departure from the above Rules necessary in order to avoid immediate danger.

PART D.—MISCELLANEOUS

RULE 28

(a) When vessels are in sight of one another, a power-driven vessel under way, in taking any course authorized or required by these Rules, shall indicate that course by the following signals on her whistle, namely:

One short blast to mean "I am altering my course to starboard." Two short blasts to mean "I am altering my course to port." Three short blasts to mean "My engines are going astern."

(b) Whenever a power-driven vessel which, under these Rules, is to keep her course and speed, is in sight of another vessel and is in doubt whether sufficient action is being taken by the other vessel to avert collision, she may indicate such doubt by giving at least five short and rapid blasts on the whistle. The giving of such a signal shall not relieve a vessel of her obligations under Rules 21 and 29 or any other Rule, or of her duty to indicate any action taken under these Rules by giving the appropriate sound signals kid down in this Rule.

(c) Nothing in these Rules shall interfere with the operation of any special rules made by the Government of any nation with respect to the use of additional whistle signals between ships of war or vessels sailing under convoy.

RULE 29

Nothing in these Rules shall exonerate any vessel, or the owner, master or crew thereof, from the consequences of any neglect to carry lights or signals, or of any neglect to keep a proper look-out, or of the neglect of any precaution which may be required by the ordinary practice of seamen, or by the special circumstances of the case.

RULE 30

RESERVATION OF RULES FOR HARBORS AND INLAND NAVIGATION

Nothing in these Rules shall interfere with the operation of a special rule duly made by local authority relative to the navigation of any harbor, river, lake, or inland water, including a reserved seaplane area.

RULE. 31

DISTRESS SIGNALS

When a vessel or seaplane on the water is in distress and requires assistance from other vessels or from the shore, the following shall be the signals to be used or displayed by her, either together or separately, namely:

(a) A gun or other explosive signal fired at intervals of about a minute.

(b) A continuous sounding with any fog-signal apparatus.

(c) Rockets or shells, throwing red signal fired one at a time at short intervals.

(d) A signal made by radiotelegraphy or by any other signaling method consisting of the group ...?? ?? ?? ... in the Morse Code.

(e) A signal sent by radio telephony consisting of the spoken word "Mayday."

(f) The International Code Signal of distress indicated by N.C.

(g) A signal consisting of a square flag having above or below it a ball or anything resembling a ball.

(h) Flames on the vessel (as from a burning tar barrel, oil barrel, &c).

(i) A rocket parachute flares showing a red light.

The use of any of the above signals, except for the purpose of indicating that a vessel or a seaplane is in distress, and the use of any signals which may be confused with any of the above signals, is prohibited.

Note.-A radio signal has been provided for use by vessels in distress for the purpose of actuating the auto-alarms of other vessels and thus securing attention to distress calls or messages. The signal consists of a series of twelve dashes, sent in 1 minute, the duration of each dash being 4 seconds, and the duration of the interval between two consecutive dashes 1 second.

RULE 32

All orders to helmsmen shall be given in the following sense: right rudder or starboard to mean "put the vessel's rudder to starboard"; left rudder or port to mean "put the vessel's rudder to port."

ANNEX C

RESOLUTIONS

RESOLUTION 1

CARRIAGE OF PASSENGERS IN EXCESS OF CONVENTION LIMITS THE INTERNATIONAL CONFERENCE ON SAFETY OF LIFE AT SEA, 1948.

RECOGNIZING

That as a consequence of the situation created by the Second World War the number of passengers needing to be carried by sea at the present time is still considerably greater than the passenger accommodation available, and that a number of Governments signatory to the International Convention for the Safety of Life at Sea, 1929, have accordingly been obliged to allow passengers to be carried in their ships in excess of the limits allowed by that Convention.

RESOLVES

That Government should each bring their practice into conformity with the provisions of the said Convention as soon as practicable, and in any event not later than the 31st day of December, 1950.

RESOLUTION 2

SPAIN

In view of the Resolution of the General Assembly of the United Nations dated 12th December, 1946, the Conference considers that Spain is, for the present, prevented from becoming a party to the International Convention for the Safety of Life at Sea, 1948.

The Conference, however, agrees that Spain may, as soon as the Resolution of the General Assembly of the United Nations shall be abrogated or shall cease to be applicable, become a party to the International Convention for the Safety of Life at Sea, 1948, in accordance with Article X of the said Convention.

ANNEX D

RECOMMENDATIONS

Throughout the following Recommendations "the present Convention" means the International Convention for the Safety of Life at Sea, 1948.

1. Denunciation of the International Convention for the Safety of Life at Sea,
1929.

The Conference recommends:

That Government should accept the present Convention at as early a date as possible, and

That the Governments which become parties to the present Convention should denounce the International Convention for the Safety of Li ft. at Sea, 1929, and should co-operate with one another with a view to ensuring that their respective denunciations become effective on dates as near as possible to, but not sooner than, the date on which the present Convention comes into force in respect of the Governments which have denounced the Convention of 1929.

2. Special Application of Convention Standards

The Conference, having excluded cargo ships of less than 500 tons gross tonnage and fishing vessels from the scope of particular provisions of the present Convention in recognition that the Convention requirements in question might not be applicable to such ships without modification, recommends that Governments should apply the principles of the present Convention to all such ships belonging to their countries as far as is reasonable and practicable.

The Conference, recognizing that the safety of life at sea will be promoted by the fullest possible availability of radio on ships, recommends that all Governments should consider the possibility of extending with such modifications as may be necessary the requirements for radio installations so that such installations should, in so far as practicable, be carried by ships, including coasting ships and fishing vessels, not covered by the present Convention, on voyages in the open sea.

The Conference further recommends that Governments should take steps to ensure that, when ports in their countries are used by ships belonging to countries whose Governments are not parties to the present Convention, such ships are required to conform to standards not lower than those prescribed by the present Convention.

3. Amendments of the Convention Provisions Relating to Construction

WHEREAS

The Conference has made provision for such amendments to the Regulations annexed to the present Convention as may prove necessary or desirable, but it is the opinion of the Conference that new developments in the art of shipbuilding or in the materials available for ship construction should not call for amendment of the Regulations until their worth has been proved.

The Conference therefore

RECOMMENDS

That Governments or the Intergovernmental Maritime Consultative Organization in applying the provisions of Article IX, which gives them discretion as to the time of the application of amended Regulations governing construction, should take the above factor into consideration.

4. Standards of Watertight Subdivision of Passenger Ships

The Conference has given careful consideration to the question of the watertight subdivision of passenger ships in the light of the results achieved since the International Convention for the Safety of Life at Sea, 1929, came into force, and has agreed on certain additional requirements calculated to secure greater safety. It recognizes, however, that the question of watertight subdivision deserves continued study, including in particular the operation of the Criterion of Service formula by which the factors of subdivision applicable to ships are determined.

The Conference therefore recommends Administrations to continue the study of this subject and to interchange the results of their study from time to time though the Authority charged with the circulation of information on matters within the scope of the present Convention.

5. Intact Stability

The Conference has considered the necessity for and the practicability of adopting Regulations for intact stability. Inasmuch as the rules which have been adopted for damage stability will affect intact stability, the Conference is of the opinion that additional experience should be gained to determine the extent to which any additional Regulations dealing with intact stability are required, before promulgating such rules.

The Conference recommends, however, that a further study be made by Governments of the subject of intact stability and that information on this subject be exchanged between Governments.

6. Openings in Bulkheads and Shell Plating

The Conference recognizes the objection which attaches to openings, which may sometimes be open at sea; in the shell plating of ships and in the main transverse watertight bulkheads, but the Conference does not consider that it is practicable to adopt international regulations concerning such openings which are more exacting than those incorporated in the present Convention.

The Conference recommends, however, that the various Governments make special efforts to ensure that the number of such openings, particularly hinged side scuttles below the margin line and doors low down in the machinery space bulkheads, be kept at the minimum required in each case.

7. Metal Hatchway Covers

The Conference has considered the use of metal hatchway covers on weather decks.

The Conference recommends Governments to exchange information regarding their experience as to the respective efficacy of metal and wood hatchway covers for preventing the spread of fire and other matters within the scope of the present Convention.

8. Fire Hose Couplings

The Conference, having been apprised that difficulty and delay are experienced in using shore-based fire-fighting facilities to deal with fires on board ships in port, owing to differences between the couplings of ships' fire hoses and those used by shore establishments recommends that endeavors should be made towards securing the standardization of all such couplings by international agreement.

9. Cyclone Warnings

The Conference considers that it is better to prevent disaster than merely to render assistance. Use may be made of the auto alarm to prevent disaster.

The Conference recommends Governments to authorize selected radiotelegraph coast stations to precede the initial broadcasting of urgent cyclone warnings by the alarm signal, wherever such a procedure is suitable (e.g., where the station is itself near the centre or anticipated path of the cyclone). In order to minimize interference where several countries lie close together adjoining a sea area, a single coast station might be selected by agreement between the Governments of those countries to make these broadcasts for the area.

10. Frequencies

The Conference draws the attention of Governments to the advisability of ensuring that radiotelegraph signals of distress utilizing emissions of Class A2 shall be effective over a sufficiently wide band of frequencies.

The Conference also desires to draw attention to the provisions of the Radio Regulations relating to radiotelephone transmissions on frequencies in the neighborhood of the radiotelegraph distress frequency and to point out that such transmissions will render inoperative auto alarm receivers working on the alarm signal defined in the above-mentioned Regulations. The Conference desires therefore to emphasize the importance, in the interest of safety of life at sea, of avoiding the use of radiotelephone transmission in the neighborhood of the distress frequency, except in case of emergency.

11. Listening for— Distress Calls, &c.

The Conference, recognizing that shore-based radio facilities make important contributions to safety of life at sea, recommends:

1. That Governments give consideration to establishing and maintaining, so far as is practicable during the hours of service, continuous listening on the distress frequency prescribed by the Radio Regulations, by a qualified operator using some aural means, in coastal radiotelegraph stations which work in the medium frequency bands.

2. That Governments give consideration to establishing and maintaining, so far as is practicable during the hours of service, continuous listening on the high frequency radiotelegraph frequency prescribed by the Radio Regulations for survival craft, by a qualified operator using some aural means, in at least one of the land radiotelegraph stations under their jurisdiction which work in the high frequency bands.
3. That in order to encourage for safety purposes the installation of radiotelephone equipment in small ships, each Government, so far as is practicable, endeavor to establish or encourage the establishment of coastal telephone stations working in the medium frequency telephone bands.

4. That each Government, having regard to the area served by its radiotelephone coast stations, endeavor to maintain during the hours of service, continuous listening (by some aural means), so far as is practicable, in a sufficient number of radiotelephone coast stations under its jurisdiction, to reduce to a minimum the possibility of a radiotelephone distress call not being received.

12. Radio telegraphy Distress Facilities in Radiotelephone Installations

The Conference recommends that Governments consider the desirability of radiotelephone installations in ships not equipped with radiotelegraphy being capable of transmitting in distress using the frequency and a class of emission assigned by the Radio Regulations to radiotelegraph stations for distress purposes, and being also provided with an automatic keying device for transmitting the alarm signal.

13. Depth-sounding Apparatus

The Conference recommends that Governments should encourage the development and use of reliable echo depth-sounding apparatus.

14. Lights on Land

The Conference recommends that, so far as practicable, steps should be taken by the Governments concerned to regulate the position and the intensity of lights on land in the vicinity of the entrances to ports so as to ensure that such lights cannot be mistaken for, or do not impair the visibility of, the navigation lights of the port.

15. Transmission of Weather Messages

The Conference, recognizing the value to safety at sea of radio weather messages from ships transmitted to appropriate shore stations in accordance with Regulation 4 of Chapter V of the present Convention, recommends that each Government should endeavor to arrange that such messages shall be free of cost to the ship concerned.

16. Manning

The Conference, recognizing that safety of life at sea is dependent not only on the construction and equipment of ships, the arrangements made to provide all possible aids to navigation and those made to ensure that assistance is afforded to ships in distress, but also on the adoption of measures as provided in Regulation 13 of Chapter V of the present Convention for the purpose of ensuring that from the point of view of safety all ships are sufficiently and efficiently manned,
having noted:

1. That the International Labor Organization has been concerned with manning and has adopted Conventions relating to

(a) minimum requirements of professional capacity for masters and officers on board merchant ships; and

(b) the certification of able seamen.

2. That the constitution of the Intergovernmental Maritime Consultative Organization provides

(a) that the Organization shall, through the Maritime Safety Committee, have the duty of considering, inter alia, matters relating to manning from the safety point of view; and

(b) that the Maritime Safety Committee shall also have the duty of maintaining such close relationships with other intergovernmental bodies concerned with transport and communications as may further the object of the Organization in promoting maritime safety,

RECOMMENDS

that the Intergovernmental Maritime Consultative Organization, when formed, and the International Labor Organization should maintain the closest liaison and should arrange for a joint examination of this problem in order to ensure:

(a) that the jurisdiction of each in regard to this question of manning is clearly defined; and

(b) that consideration is given to the question whether it is necessary to propose minimum manning standards for adoption internationally.

17. Medium Frequency Direction Finding and Radio Beacons

The Conference, recognizing that medium frequency direction finding will continue to provide a valuable navigational aid, recommends that the existing systems of radio beacons provided for use in connection with ship borne medium frequency direction finders should be maintained universally at a standard not below that at present provided, and that in certain areas (notably those where such systems are established) they should be improved and expanded as navigational needs require and opportunity affords. It also recommends that the Maritime Safety Committee study this question, particularly as regards the adoption of a uniform system of radio beacon operating procedure and characteristics.

18. Radio Aids to Navigation

The Conference, recognizing that the recent advances in radio technique are of great service to shipping, recommends that:

(a) Governments should recognize the desirability of adopting new equipment, devices or systems incorporating advanced techniques in radio aids to navigation which have proved operationally useful or necessary in the promotion of safe navigation.

(b) Governments should study all available information concerning the development of electronic systems of position-fixing, with special reference to their suitability for use in their countries and by their countries' ships.

(c) Governments should ensure that in the selection of systems of navigational aids for aircraft and ships due weight is given to the relative advantages of the various systems from both points of view, and that when systems are selected that can serve the needs of both ship and aircraft they shall be so organized and operated as to serve those needs as fully as practicable.

(d) Governments should participate in the regular exchange of information on the whole subject of radar and radio navigational aids.

(e) The Maritime Safety Committee should regard the subject of radio navigational aids as one of fundamental importance for increasing the safety of navigation, should initiate or pursue such special studies of various aspects of the problem as may seem necessary or desirable, and should undertake the coordination and distribution of the information in this field referred to in paragraph (d) above.

19. Navigation of Ships Equipped with Radar, &c.

The Conference, while recognizing that the recent advances in radar and electronic navigational aids are of great service to shipping, is of the opinion that the possession of any such device in no way relieves the master of a ship from his obligation strictly to observe the requirements laid down in the International Regulations for Preventing Collisions at Sea, and in particular, the obligations contained in Articles 15 and 16 of those Regulations.

The Conference recommends that Governments should call the attention of masters and officers to this opinion.

20. RADAR

THE CONFERENCE,

RECOGNIZING:

1. That high resolution ship borne radar, having suitable and approved minimum performance capabilities and a simple and reliable overall performance monitor, is a device having wide applicability to maritime use for anti-collision, pilot age, above water obstacle detection, and general position-fixing, within range of suitable fixed radar targets either natural or artificial (active and passive). A high resolution radar should have, among other characteristics, the following:—

(a) Minimum range. Provide display of a target down to a minimum range of 100 yards;

(b) Bearing resolution. Provide display, as two separate indications, of targets at the same range separated by not more than 3° in azimuth;

(c) Range resolution. Provide display, as two separate indications, on the shortest range scale of targets on the same azimuth separated by 100 yards in range.

2. That a ship borne radar with reduced performance requirements and generally understood to be an anti-collision radar against large ships is completely inadequate for the full needs of position-fixing and navigation in coastal and pilot age waters.

RECOMMENDS:

(a) That Governments encourage the development, manufacture, and installation of ship borne radar on board their ships, taking these facts into account;

(b) That the Governments of the countries in which such apparatus is manufactured consider the possibility of issuing specifications serving as an indication of the standards desired for the industry and the purchasers of such apparatus;

(c) That Government should encourage the training of personnel in the use of ship borne radar.

21. Uniform Buoy age

The Conference, recognizing that unification of buoy age, regional or worldwide, would greatly contribute to the safety of navigation, recommends Governments to unify, so far as may be practicable, the systems of buoy age employed in the various waters open to international navigation. It also recommends that a further study of this matter be undertaken by the Maritime Safety Committee, as soon as may be possible.

22. Carriage of Dangerous Goods

The Conference recognizes the great importance of securing international uniformity in the safety precautions applicable to the carriage of dangerous goods by sea, but, in view of the complexity of the subject, considers that much more time than is available at the Conference would be necessary to secure agreement on detailed regulations. Such regulations already exist in certain countries possessing an extensive export trade in chemicals and these are available in the meantime for the guidance of the Governments of other countries in applying the provisions of Regulation 3 of Chapter VI of the present Convention.

The Conference recommends that the subject should receive further study as a matter of urgency either by the Maritime Safety Committee or by the representatives of the Governments chiefly concerned in consultation with one another, with the object of international regulations being drafted as soon as possible for consideration and adoption by the Governments of all countries from which dangerous goods are exported.

The Conference also recommends that the further study to be given to the subject should include the question whether it would be practicable to frame a system of marking dangerous goods by distinctive symbols or designs so as to distinguish them according to the kind of danger which they respectively involve.

23. Coordination of Safety at Sea and in the Air

The Conference,

Having considered the Report of the Preparatory Committee of Experts on Coordination of Safety at Sea and in the Air submitted to the Conference;

Having recognized that it is desirable to coordinate activities regarding safety on and over the sea;

Having taken into account while drawing up the present Convention the recommendations contained in the said Report and those submitted by the International Organizations concerned;

Recommends that, for the common goal of safety, co-operative action be continued and strengthened along the lines suggested in the Report.
