Points to pounder:
In calculating the effect of free surfaces of consumable liquids, it shall be assumed that for each type of liquid at least one transverse pair or a single centre line tank has a free surface, and the tank or combination of tanks to be taken into account shall be those where the effect of free surfaces is the greatest.
It is of great importance to the safety of the vessel that all tanks are included in calculations regarding the corrected GMt.
If the contents of one or more ballast tanks will change during the voyage, this has to be considered in the stability calculations.
