Question 4652 Deck General

The correct answer is B) frames and beam brackets. Stanchions are vertical supports that prevent the entire deck load on a Mobile Offshore Drilling Unit (MODU) from being carried solely by the frames and beam brackets. The frames and beam brackets are the primary structural members that provide support and distribute the deck load across the vessel. Stanchions help to distribute the load more evenly, preventing excessive stress on the frames and beam brackets. The other answer choices are incorrect because stringers (A) are longitudinal members that provide additional support, bulkheads (C) are vertical partitions, and deck longitudinals (D) are also longitudinal members, but none of these directly support the entire deck load in the same way as the frames and beam brackets.
