what are IMO regulations for carrying bulk grain cargo ?

 IMO regulation for grain carriage :

The following are the intact stability requirements for a vessel carrying bulk grain:

  1. The angle of heel due to a grain shift shall not exceed 12 degrees
  2. In the statical stability diagram, the residual area between the heeling arm curve and the righting arm curve up to :
    1. Angle of heel of maximum difference between the co-ordinates of the two curves
    2. 40 degrees
    3. Angle of flooding
    4. Whichever of these 3 angles is the least, shall not be less than 0.075m-radians.
  3. The initial metacentric height after correction for the FSE of liquids in tanks, shall not be less than 0.30 m.

In order to reduce or eliminate the adverse heeling effect of grain shift, the following methods may he used:

  • a) Shifting Board    (F+P)
  • b) Over stowing        (F+P)
  • c) Strapping and Lashing   (F+P)
  • d) Bundling                (F)
  • e) Saucering               (F)
  • f) Feeders                   (F)
