Regulation 5 - Subdivision and damage stability

  5(b)(iii) Applies.

  5(c)(i)(1) The requirements for the GM values (in the final stage of flooding) are to be replaced by the requirements given in USSR paper SLF 35/4/9 - See later for a full description of these requirements.

  5(c)(i)(2) The maximum permitted equilibrium angle after flooding is included in the requirements of regulation 5(c)(i)(1).

  5(c)(i)(3) This is to be interpreted as non-immersion of the bulkhead deck - note that this is not the margin line - in the final stage of flooding.

  5(c)(ii) Applies.

  5(c)(iii) Applies.

In respect of the time for equalisation of cross-connected spaces, the provisions of regulation A.266(VIII) should be applied.

  5(c)(iv) Applies.

A standard of residual stability during the intermediate stages of flooding, for the purposes of this exercise only, is to be governed by the heel angle given in this regulation, i.e. 20°.

  5(d) Applies, except that in place of the final sentence - “For each initial trim ... flooded condition" put “The ship shall be at its design trim (i.e. zero trim in most cases) at the deepest subdivision loadline".
