Question 1877Deck Safety70% to pass
The floors in a vessel's hull structure are kept from tripping, or folding over, by _______________.
AI Explanation
The correct answer is D) bottom longitudinals.
The floors in a vessel's hull structure are kept from tripping or folding over by the bottom longitudinals. Longitudinals are structural members that run lengthwise along the bottom of the hull, providing strength and preventing the floors from collapsing inward. This is a key structural feature required by the US Coast Guard regulations for the construction and stability of commercial vessels.
The other options are incorrect because transverse deck beams (A) run across the vessel, not lengthwise, and face plates (C) and longitudinal deck beams (B) are not the primary structural elements that prevent the floors from tripping in the bottom of the hull.
