A jack-up displacing 350,000 cubic feet while floating in sea water (64 pounds per cubic foot) weighs __________.

Correct Answer: Option C — 22,400 kips

Displacement weight equals volume multiplied by saltwater density (64 lbs/cu ft). Multiplying 350,000 cubic feet by 64 pounds yields 22,400,000 pounds, which converts to 22,400 kips by dividing by 1,000 pounds per kip, in accordance with standard marine architecture principles.
