Question 4668 Deck General
70% to passThe DEEP DRILLER, at a draft of 60 feet, has -3,600 ft-tons of transverse moments. How much ballast should be transferred between tanks 10P and 10S to level the unit in list?
A
25.1 long tons
B
50.2 long tons
C
62.8 long tons
D
252.1 long tons
AI Explanation
The correct answer is A) 25.1 long tons. To level the DEEP DRILLER unit, the transverse moments need to be balanced. With a transverse moment of -3,600 ft-tons, 25.1 long tons of ballast should be transferred from tank 10P to tank 10S to bring the unit back to an even keel. The other options are incorrect because they do not accurately reflect the amount of ballast required to balance the transverse moments. Option B (50.2 long tons) is too much, Option C (62.8 long tons) is also too much, and Option D (252.1 long tons) is significantly too high.
