Chapter 2 - Stability and subdivision

1 The existing paragraph 2.2 is replaced by the following:

  • "2.2 The subdivision and damage stability of special purpose ships should in general be in accordance with SOLAS chapter II-1 where the ship is considered a passenger ship, and special personnel are considered passengers, with an R-value calculated as follows:

    • .1 where the ship is certified to carry 240 persons or more, the R-value is assigned as R;

    • .2 where the ship is certified to carry not more than 60 persons, the R-value is assigned as 0.8R; and

    • .3 for more than 60 (but not more than 240) persons, the R-value should be determined by linear interpolation between the R-values given in .1 and .2 above.

  • Where:

  • N = N1 + 2N2

  • N1 = number of persons for whom lifeboats are provided

  • N2 = number of persons (including officers and crew) the ship is permitted to carry in excess of N1

2 The following new paragraph 2.3 is added after the amended paragraph 2.2 and the existing paragraphs 2.3 to 2.5 are renumbered accordingly:

  • "2.3 Where the conditions of service are such that compliance with paragraph 2.2 above on the basis of N = N1 + 2N2 is impracticable and where the Administration considers that a suitably reduced degree of hazard exists, a lesser value of N may be taken but in no case less than N = N1 + N2."
