Question 4680 Deck General

The correct answer is B) decks. In MODU (Mobile Offshore Drilling Unit) construction, beams are transverse girders that provide primary support to the decks. Beams are horizontal structural members that span between vertical supports, such as frames or bulkheads, and are designed to carry the weight of the deck and any equipment or personnel on it. The other options are incorrect because: A) Deckhouse structures are supported by the deck, not the beams. C) Vertical frames are supported by the beams, not the other way around. D) Bulkheads are vertical structural members, not the primary support for the decks.
