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 port leg reaction?

Correct Answer: Option D — 7,203 kips

Applying total weight, longitudinal moments (LM), and transverse moments (TM) to the rig's leg reaction formula accounts for eccentric loading. With 21,401 kips total weight and the given moments, static load distribution calculations determine the port leg reaction to be 7,203 kips.
