Question 5010Deck General70% to pass
How much drill water should be transferred from tanks 23 and 24 to tank 1 to level the COASTAL DRILLER, in transit at a draft of 10 feet 6 inches, if the total longitudinal moments are 1,700,000 ft-kips?
AI Explanation
The correct answer is B) 451 kips.
To explain:
1. The question is asking about the amount of drill water that should be transferred from tanks 23 and 24 to tank 1 to level the COASTAL DRILLER at a draft of 10 feet 6 inches, given the total longitudinal moments of 1,700,000 ft-kips. Based on the information provided, the correct answer is 451 kips.
2. The reasoning for this is that the transfer of ballast water between tanks is a common stability adjustment procedure for vessels like the COASTAL DRILLER. The goal is to maintain the desired draft and trim by adjusting the distribution of weights on board. With the total longitudinal moments provided, the correct amount of water transfer from the specified tanks can be calculated to achieve the target 10 feet 6 inches draft.
3. The other options are incorrect because they do not accurately reflect the necessary water transfer amount based on the given information and stability requirements.
