The list due to grain shift must not be greater than 12 degrees. | |
The residual area between HAC and RAC up to 40 degrees or angle of flooding, whichever is less, shall not be less than 0.075 m-r. | |
The initial GM after correction for free surface effect must not be less than 0.30m. |
In calculating suitable stability, following assumptions were made:
When the deck head slopes at less than 30 degrees to the horizontal, a void is assumed the depth of which can be ascertained by formula. | |
There is a void of average depth 15cm below the hatch cover. | |
Grain is assumed to move in a prescribed pattern such that the voids change shape and the grain surface moves 15 degrees to the horizontal. |
