Question 4677 Deck General

The correct answer is C) deck beams. The decks of a Mobile Offshore Drilling Unit (MODU) are supported by transverse members called deck beams. Deck beams are the primary structural members that run across the width of the vessel, providing support and distributing the weight of the deck and any equipment or cargo on it. The other options are incorrect because: A) trusses are not commonly used to support MODU decks, B) web frames are vertical structural members, not transverse, and D) deck longitudinals run along the length of the vessel, not across the width.
