2 Subject to section 6 of this Schedule, the length of a compartment shall not exceed its permissible length; the permissible length of a compartment having its centre at any point shall be the product of the floodable length at that point and the factor of subdivision of the ship; to enable the permissible length of compartments to be determined, it will be necessary to develop flooding curves that will indicate the floodable length at any point in the ship; flooding curves should be developed by a method of calculation that takes account of the form, draught and other characteristics of the ship; the method described in Division IV of this Schedule should normally be used; if, however, the ship is of such unusual form that this method is not sufficiently accurate, the Board may permit the use of an alternative method of calculation.
Hull Construction Regulations — 3
3 The assumptions of permeability, which shall be taken into account in determining the floodable length at any point in ships to which this Division applies, shall be as follows: (a) machinery space: (i) in the case of ships not propelled by internal combustion engines, the assumed average permeability throughout the machinery space shall be determined by the following formula: 80 + 12.5 (a - c) v where a = volume of the passenger spaces and crew spaces below the margin line within the limits of the machinery space; c = volume of the between deck spaces below the margin line within the limits of the machinery space which are appropriated to cargo, coal or stores; and v = volume of the machinery space below the margin line, (ii) in the case of ships propelled by internal combustion engines, the average permeability throughout the machinery space shall be taken as five greater than that given by the aforesaid formula, and (iii) in any case in which the average permeability throughout the machinery space, as determined by detailed calculation, is less than that given by the aforesaid formula, the calculated value may be substituted; for the purposes of such calculation, the permeability of passenger spaces and crew spaces shall be taken to be 95, that of all spaces appropriated for cargo, coal or stores shall be taken to be 60, and that of double bottom, oil fuel and other tanks forming part of the structure of the ship shall be taken to be 95 or such lesser figure as the Board may approve in the case of that ship; and (b) portions before and abaft the machinery space: (i) the assumed average permeability throughout the portions of the ship before and abaft the machinery space shall be determined: (A) by the following formula: 63 + 35 a v where a = volume of the passenger spaces and crew spaces which are situated below the margin line before or abaft the machinery space, as the case may be; and v = volume of the portion of the ship below the margin line before or abaft the machinery space, as the case may be, or (B) if the Board so determines in the case of any ship, after receipt of a plan of the ship showing the watertight subdivisions thereof, by detailed calculation, for the purpose of which the permeability of spaces shall be assumed to be as follows: passenger spaces 95 crew spaces 95 spaces appropriated to machinery 80 spaces appropriated to cargo, coal, stores or baggage rooms 60 tanks forming part of the structure of the ship and double bottoms 95, or such lesser figure as the Board may permit in the case of any ship; and (ii) for the purposes of this section, a space within a passenger space or crew space shall be deemed to be a part thereof unless it is appropriated for other purposes and is enclosed by permanent steel bulkheads.

4 (1) Subject to subsection (4), in the case of ships the length of which is 131 m or more, the factor of subdivision F shall be determined by the following formula: F = A - (A - B) ( C s - 23) 100 where A and B are respectively determined in accordance with subsection (5) and C s is the criterion numeral determined in accordance with section 5 of this Schedule, provided that where in the case of any ship the factor F is less than 0.4 and the Board is satisfied that it is impracticable to apply the factor F in determining the permissible length of a compartment appropriated for machinery, the Board may allow an increased factor not exceeding 0.4 to be applied to that compartment. (2) Subject to subsection (4), in the case of ships the length of which is less than 131 m but not less than 79 m having a criterion numeral of not less than 3574 - 25L 13 (hereinafter in this section referred to as S), the factor of subdivision F shall be determined by the following formula: F = 1 (1 - B) ( C s - S) 123 - S where B is the factor determined in accordance with subsection (5) and C s is the criterion numeral determined in accordance with section 5 of this Schedule. (3) In the case of ships the length of which is less than 131 m but not less than 79 m and having a criterion numeral less than S or in the case of ships the length of which is less than 79 m the factor of subdivision shall be unity. (4) In the case of a ship of any length which is intended to carry a number of passengers exceeding 12 but not exceeding L 2 650 or 50 whichever is the lower, the factor of subdivision shall be determined in the manner provided in subsection (3). (5) For the purposes of this subsection the factors A and B shall be determined by the following formulae: A = 58.2 L - 60 + 0.18 (where L = 131 and upwards) B = 30.3 L - 42 + 0.18 (where L = 79 and upwards).
Hull Construction Regulations — 5
5 The criterion numeral for ships to which this Division applies shall be determined by the following formulae: When P 1 is greater than P C s = 72 M + 2 P 1 V + P 1 - P and in all other cases C s = 72 M + 2P V where C s = the criterion numeral; M = the volume of the machinery space, 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 volume of the passenger spaces and crew spaces below the margin line; V = the volume of the ship below the margin line; N = number of passengers which the ship is intended to carry; and P 1 = 0.056LN provided that: (a) where the value of 0.056LN is greater than the sum of P and the whole volume of the passenger spaces above the margin line, the figure to be taken as P 1 shall be that sum or 0.037LN whichever is the greater; (b) values of C s less than 23 shall be taken as 23; and (c) values of C s greater than 123 shall be taken as 123.
Hull Construction Regulations — 6
 less than 0.03L + 3.05 m, or 10.67 m, or 0.1L, whichever is the least, only one of those bulkheads shall be regarded as forming part of the subdivision of the ship; for Class V and Class VIII vessels, this minimum spacing shall be applicable between peak bulkheads. Allowance for Local Subdivision (7) Where in any ship a main transverse watertight compartment contains local subdivision and the Board is satisfied that, after any assumed side damage extending over a length of 0.03L + 3.05 m, or 10.67 m, or 0.1L, whichever is the least, 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.
Hull Construction Regulations — 7
7 Subject to the modifications set forth in this Division, the maximum length of compartments in ships to which this Division applies shall be determined as if they were ships to which Division II applies.
