What is Purpose of the code on intact stability?

  1. A general  description   of the ship;
  2. Instructions  on the use of the booklet;
  3. General  arrangement   plans  showing  watertight   compartments,    closures,  vents,  downflooding angles, permanent   ballast, allowable  deck  loadings  and freeboard  diagrams;
  4. Hydrostatic  curves or tables and cross curves of stability  calculated  on a free-trimming   basis, for the  ranges of displacement   and trim  anticipated   in normal  operating  conditions;
  5. Capacity  plan or tables showing  capacities and centres of gravity for each cargo stowage  space;
  6. Tank sounding  tables showing  capacities,  centres of gravity, and free surface data for each tank;
  7. Information   on  loading  restrictions,  such as maximum  KG or minimum   GM  curve  or table  that can be used to determine  compliance   with  the applicable  stability  criteria;
  8. Standard operating  conditions  and examples for developing  other  acceptable  loading  conditions using the information   contained   in the stability  booklet;
  9. A brief  description   of the stability  calculations  done,  including  assumptions;
  10. General  precautions  for  preventing  unintentional   flooding;
  11. Information   concerning  the use of any special cross-flooding  fittings with  descriptions  of damage conditions  which  may require  cross-flooding;
  12. Any other  necessary guidance  for  the safe operation   of the  ship under  normal  and emergency conditions;
  13. A table  of contents  and index for each booklet;
  14. Inclining  test report  for the ship, or:
    • where the stability  data are based on a sister ship, the inclining  test report  of that sister ship along with  the light-ship  measurement  report  for the ship in question;  or
    • where light-ship particulars  are determined  by other methods  than from  inclining  of the ship or its sister, a summary  of the method  used to determine  those  particulars;

Recommendation    for determination   of ship’s stability  by means of an in-service inclining  test.
