Question 1914 Deck Safety

The correct answer is D) To provide strength to shell plating at the stern. Cant frames are structural members used in the stern of steel vessels to provide additional strength and support to the shell plating in that area. The stern of a ship experiences higher stresses and loads compared to other parts of the hull, so the cant frames help reinforce the shell plating and prevent deformation or damage. The other answer choices are incorrect because they do not accurately describe the primary purpose of cant frames. Answer A is incorrect as cant frames are not used to support cylindrical tanks. Answer B is incorrect as cant frames do not specifically support the overhang of the stern. Answer C is incorrect as cant frames provide strength to the shell plating, not the deck beams.
