The COASTAL DRILLER, with no trim, is at a true mean draft of 10 feet and 10 inches. TM is -6,800 ft-kips. Using only tanks 1, 25, and 26, how many kips of drill water must be transferred to level the jack-up?

Correct Answer: Option D — Transfer 100 kips from 25 to 26

Correcting trim on the COASTAL DRILLER requires shifting ballast longitudinally. Transferring 100 kips from tank 25 (aft) forward to tank 26 (forward) alters the longitudinal center of gravity and eliminates the negative longitudinal moment, leveling the jack-up according to stability manual guidelines.
