The COASTAL DRILLER, while drilling, has a total weight of 15,400 kips. The LCG is 120.00 feet AF0, and the TCG is -0.5 feet to port of the centerline. What is the port leg reaction?

Correct Answer: Option C — 5,233 kips

Leg reaction calculations for jack-up mobile offshore drilling units utilize hydrostatic equilibrium equations factoring total weight, longitudinal center of gravity (LCG), and transverse center of gravity (TCG) moments relative to the baseline and centerline per 46 CFR standards, resolving to 5,233 kips for the port leg.
