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 less than 70 knots?

Correct Answer: Option D — 1,059,885 foot-tons

Operating Manual stability criteria for the DEEP DRILLER specify maximum allowable vertical moments under 70-knot wind conditions at a 60-foot draft. Based on hydrostatic tables and intact stability requirements in 46 CFR, the permissible moment limit equals 1,059,885 foot-tons.
