While preloading, the COASTAL DRILLER has a total weight of 21,401 kips. The LM are 2,560,416 ft-kips, and the TM are -6,206 ft-kips. What is the starboard leg reaction?

Correct Answer: Option A — 7,099 kips

Leg reactions during preloading are determined using total weight, longitudinal moments (LM), and transverse moments (TM). Applying statutory MODU stability calculation formulas balances these moments across the support legs, resulting in a starboard leg reaction of 7,099 kips.
