Question 4349 Deck General

The correct answer is B) 996,522 ft-tons. The maximum vertical moments, including free surface moments, permitted on the DEEP DRILLER at survival draft during the passage of a severe storm is 996,522 ft-tons. This value is derived from the applicable regulations and stability requirements for mobile offshore drilling units like the DEEP DRILLER. The other options are incorrect because A) 998,942 ft-tons exceeds the regulatory limit, C) 990,430 ft-tons is below the limit, and D) 889,555 ft-tons is significantly below the limit and does not represent the maximum permitted value.
