Question 1908 Deck Safety

The correct answer is B) web frames. In a longitudinally-framed ship, the longitudinal frames are held in place and supported by athwartship members called web frames. Web frames are structural members that run transversely across the ship's hull, perpendicular to the longitudinal frames, and provide crucial support and reinforcement to the overall frame of the vessel. The other options are incorrect because: A) stringers are longitudinal members that run parallel to the frames, C) floors are transverse structural members at the bottom of the hull, and D) margin plates are used to reinforce the edges or sides of the hull.
