A floating jack-up with displacement of 15,000 kips has its LCG 106 feet aft of frame zero (AF0). If 200 short tons are loaded at 20 feet AF0 and 400 short tons are loaded 149 feet AF0, what is the new LCG?

Correct Answer: Option B — 106.0 feet

Longitudinal moments must balance consistently using uniform units. Converting short tons to kips or maintaining consistent weight units when calculating $\frac{\Sigma \text{ Moments}}{\Sigma \text{ Weights}}$ against the 106-foot baseline displacement yields a resulting new LCG of exactly 106.0 feet AF0.
