Summary:
The key to ballast water discharge depends on the actual loading conditions on board, different loading conditions discharge steps are different, there is no fixed steps. If it is discharged during the voyage, generally pay attention to the following points:
1. Ballast water discharge caused by the impact of the hull strength, shear force (shear force) and bending moment (bending moment) can not exceed the standard.
2. ballast water discharge caused by changes in draft, pay attention to the cab line of sight (visibility), propeller immersion rate (propeller immersion), the minimum draft forward and emergency fire pump suction (emergency fire pump suction) but if in harbor However, if the ballast water is discharged in a harbor, it is basically only necessary to pay attention to the effects of structural strength.
