The FSM of a tank is only used to correct GM or.
If the FSM setting is not set to “default” then it is also used to correct the righting levers. For the normal setting the software uses the actual COG of liquids in tanks which is more accurate. This is also why you see a varying GG’ as the free surface moments of tanks tend to increase or decrease with the heeling angle of a vessel.

For tanks with a filling percentage greater than 98% the IMO allows the FSM to be set to zero.
