Question 3660 Deck General

The correct answer is D) U.S. Coast Guard. The U.S. Coast Guard is responsible for approving the construction portfolio prepared for each new offshore drilling unit. This requirement is part of the Coast Guard's regulatory oversight over the design, construction, and operation of offshore drilling units in U.S. waters. The other answer choices are incorrect because the Minerals Management Service (now Bureau of Ocean Energy Management) does not approve construction portfolios, the National Cargo Bureau is focused on cargo handling and stowage, and the American Bureau of Shipping is a non-governmental classification society that does not have the authority to approve offshore drilling unit construction portfolios.
