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 520,462 ft-kips, FSML are 26,000 ft-kips, and FSMT are 25,000 ft-kips. How much should the KG corrected for free surface effects be lowered to satisfy the maximum allowable KG criteria?

Correct Answer: Option D — 0.00 feet

Evaluating MODU stability against severe storm criteria requires calculating the virtual center of gravity using vertical and free surface moments. When the resulting corrected KG already complies with or falls below the restricted maximum allowable limit, no lowering is required, resulting in a 0.00-foot adjustment.
