A jack-up with a calculated moment to change list one inch (MCL1") of 1,350 foot-kips intends to transfer drill water from a tank with a TCG of 82 feet to a tank with a TCG of 18 feet. How much weight should be transferred to change the draft on the port side from 11.0 to 11.5 feet?

Correct Answer: Option D — 253.1 kips

Transverse weight shift calculations utilize the formula Moment equals weight times distance. Given a tank transverse separation of 64 feet and an MCL1" of 1,350 foot-kips, achieving a half-foot draft change requires transferring 253.1 kips of drill water.
