Question 2406 Deck Safety

The correct answer is D) none. According to the regulations for vessel stability, the total combined cargo weight below deck and on deck cannot exceed the vessel's maximum allowable cargo capacity. In this case, the vessel already has 400 tons of below deck cargo and 230 tons of above deck cargo, totaling 630 tons. Adding another 220 tons of liquid mud below deck would exceed the vessel's maximum capacity, leaving no room for additional deck cargo. Therefore, the correct answer is that no more deck cargo can be loaded. The other options are incorrect because they suggest the vessel can load additional deck cargo, which is not possible given the existing cargo load and the maximum capacity constraint.
