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:
-
[...]
-
(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

5 The criterion numeral for ships to which this Division applies shall be determined by the following formulae:
[...]
Cs = 72 M + 2P / V
where
- 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;
