2 Documents for submission

Parent topic: Appendix - Guidelines for the Preparation of Subdivision and Damage Stability Calculations

2.1 Presentation of documents

 The documentation should begin with the following details: principal dimensions, ship type, designation of intact conditions, designation of damage conditions and pertinent damaged compartments, KG-respective GM-limit curve.

2.2 General documents

 For checking of the input data, the following should be submitted:

  • .1 main dimensions;

  • .2 lines plan, plotted or numerically;

  • .3 hydrostatic data and cross curves of stability (including drawing of the buoyant hull);

  • .4 definition of sub-compartments with moulded volumes, centres of gravity and permeability;

  • .5 layout plan (watertight integrity plan) for the sub-compartments with all internal and external opening points including their connected sub-compartments, and particulars used in measuring the spaces, such as general arrangement plan and tank plan. The subdivision limits, longitudinal, transverse and vertical, should be included;

  • .6 light service condition;

  • .7 load line draught;

  • .8 co-ordinates of opening points with their level of tightness (e.g. weathertight, unprotected);

  • .9 watertight door location with pressure calculation;

  • .10 side contour and wind profile;

  • .11 cross and down flooding devices and the calculations thereof according to resolution A.266(VIII) with information about diameter, valves, pipes length and co-ordinates of inlet/outlet;

  • .12 pipes in damaged area when the destruction of these pipes results in progressive flooding; and

  • .13 damage extensions and definition of damage cases.

2.3 Special documents

 The following documentation of results should be submitted.

2.3.1 Documentation

  2.3.1.1 Initial data:

  • .1 subdivision length Ls ;

  • .2 initial draughts and the corresponding GM-values;

  • .3 required subdivision index R; and

  • .4 attained subdivision index A with a summary table for all contributions for all damaged zones.

  2.3.1.2 Results for each damage case which contributes to the index A:

  • .1 draught, trim, heel, GM in damaged condition;

  • .2 dimension of the damage with probabilistic values p, v and b;

  • .3 righting lever curve (including GZmax and range) with factor of survivability s;

  • .4 critical weathertight and unprotected openings with their angle of immersion; and

  • .5 details of sub-compartments with amount of in-flooded water/lost buoyancy with their centres of gravity.

2.3.2 Special consideration

 For intermediate conditions as stages before cross-flooding or before progressive flooding, an appropriate scope of the documentation covering the aforementioned items is needed in addition.
