What are the maximum vertical moments, including free surface moments, permitted on the DEEP DRILLER at survival draft if the winds are greater than 70 knots?
AI Explanation
The correct answer is C) 996,522 foot-tons.
This is the correct answer because the maximum vertical moments, including free surface moments, permitted on the DEEP DRILLER at survival draft when winds exceed 70 knots is 996,522 foot-tons, as per the applicable regulations for offshore mobile drilling units.
The other options are incorrect because A) 912,120 foot-tons is too low, B) 942,120 foot-tons is also too low, and D) 998,927 foot-tons is slightly higher than the correct value of 996,522 foot-tons.
