While the COASTAL DRILLER is in transit at a draft of 10 feet 6 inches, a severe storm is predicted within 12 hours. VM are 541,257 ft-kips, FSML are 32,000 ft-kips and FSMT are 24,000 ft-kips. How much should the KGL be lowered to satisfy the maximum allowable KG criteria?

Correct Answer: Option B — 1.96 feet

When an impending severe storm reduces allowable KG thresholds, stability calculations using total vertical moments (VM) and free surface moments (FSM) determine necessary vertical weight adjustments. Comparing the actual corrected KG against the storm criteria dictates a required lowering of 1.96 feet.
