The COASTAL DRILLER is in transit loaded as shown in the Sample Load Form Number 1 (Rig Move). What would be the new KGT if, during the move, 170.9 kips of fuel oil is consumed from Diesel Oil Tanks 13 and 14?

Correct Answer: Option C — 50.70 feet

Consuming fuel oil from designated double-bottom tanks modifies total vessel weight and raises the vertical center of gravity due to removed low-level weight. Recalculating the moment summations after consuming 170.9 kips from diesel tanks 13 and 14 establishes the new transverse vertical center of gravity (KGT) at 50.70 feet.
