Question 2599 Deck Safety

The correct answer is D) 990 tons. To meet the one compartment standard, the amount of liquid loading required in the double bottom tanks is 990 tons. This is determined by using the stability data and applying the principles of the one compartment standard, which requires the vessel to remain afloat with any single compartment flooded. The other options are incorrect because they do not adequately meet the one compartment standard. Option A (395 tons) and B (530 tons) are too low, while option C (750 tons) is also insufficient to meet the stability requirements under the one compartment standard.
