Question 1826 Deck Safety

The correct answer is D) any door stated in the ship's stability book as being permitted to remain open. The International Convention for the Safety of Life at Sea (SOLAS) requires watertight doors on vessels to be kept closed while the vessel is navigating, with the exception of doors that are specifically permitted to remain open according to the ship's stability book. The stability book contains information on the vessel's design and operation, including any doors that may be left open without compromising the ship's watertight integrity and stability. The other options are incorrect because they do not represent valid exceptions to the SOLAS requirement. Ramps, machinery space doors, and cargo loading doors must generally be kept closed while the vessel is underway, unless the stability book explicitly allows them to remain open.
