Question 4720Deck General70% to pass
The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). Weather conditions make it necessary to ballast down to survival draft. It is decided to check the stability at the intermediate draft of 32 feet. How much ballast is required to ballast to 32 feet?
AI Explanation
The correct answer is C) 2,294 long tons.
The reasoning is as follows:
1. To ballast down the DEEP DRILLER to the intermediate draft of 32 feet, the vessel needs to take on additional ballast to increase its displacement.
2. The amount of ballast required is the difference between the vessel's displacement at the current draft and the displacement at the 32-foot draft.
3. The other options are incorrect because they do not accurately represent the change in displacement required to reach the 32-foot draft.
