Because there is a possibility of fuel oil being discharged overboard from a full fuel oil tank, it is decided to transfer 25 kips from tank 14 to tank 13. See COASTAL DRILLER Sample Load Form Number 1 (Rig Move). What would be the change in transverse moments with this transfer?

Correct Answer: Option D — 2010 ft-kips

Transverse moment changes equal the transferred weight multiplied by the transverse distance between tank centers. Shifting 25 kips between fuel oil tanks 14 and 13 results in a transverse moment change of 2010 ft-kips, complying with rig stability guidelines.
