Deck General USCG Question #4360 (Set 139)

The DEEP DRILLER is loaded as shown in Sample Load Form #4 (Drilling). What would be the new sum of FSML for Fresh Water if the entire contents of Drill Water Tank #5P are transferred to Tank #5S?

Official USCG Answer & Rule Citation

Correct Answer: Option C — 317 ft-tons

Transferring liquid entirely within a tank from port to starboard (such as Tank #5P to #5S) maintains the same volume and free surface inertia moment, thereby keeping the total free surface moment for fresh water unchanged at 317 ft-tons.
