Part C - Requirements for Cargo Craft

Parent topic: Chapter 2 - Buoyancy, Stability and Subdivision

2.15 Buoyancy and stability in the displacement mode following damage

 Following any of the postulated damages detailed in 2.6.5 to 2.6.7, the craft in still water should have sufficient buoyancy and positive stability to simultaneously ensure that:

  • .1 after flooding has ceased and a state of equilibrium has been reached the final waterline is 150 mm below the level of any opening through which further flooding could take place;

  • .2 the angle of inclination of the craft from the horizontal does not normally exceed 15° in any direction. However, where this is clearly impractical, angles of inclination up to 20° immediately after damage but reducing to 15° within 15 min may be permitted provided that efficient non-slip deck surfaces and suitable holding points, e.g., holes, bars, etc., are provided;

  • .3 there is a positive freeboard from the damage waterline to survival craft embarkation positions;

  • .4 essential emergency equipment, emergency radios, power supplies and public address systems needed for organizing the evacuation remain accessible and operational;

  • .5 the residual stability of multihull craft complies with the appropriate criteria as laid out in annex 7; and

  • .6 the residual stability of any other craft meets the requirements of regulation II-1/8 of the Convention.

2.16 Inclining

 Where it is satisfied by lightweight survey, weighing or other demonstration, that the lightweight of a craft is closely similar to that of another craft of the series to which 2.7.1 has been applied, the Administration may waive the requirement of 2.7.1 for craft to be inclined. In this regard, a craft which lies within the parameters of 2.14.1, when compared with a craft of the series which has been inclined, should be regarded as being closely similar to that craft.
