What are the maximum vertical moments including free surface moments permitted on the DEEP DRILLER at a draft of 60 feet if the winds are greater than 70 knots?

Correct Answer: Option B — 942,120 foot-tons

Environmental load curves for winds exceeding 70 knots impose strict caps on allowable vertical moments. At a 60-foot operational draft, the maximum allowable vertical moment including free surface moments is constrained to 942,120 foot-tons to maintain required positive stability margins under USCG MODU rules.
