The DEEP DRILLER, at a draft of 60 feet, has 50,000 ft-tons of longitudinal moments. How much ballast should be transferred between tanks 1P and 10P to level the unit longitudinally?

A 45.3 long tons

B 90.6 long tons

C 118.1 long tons

D 236.1 long tons

AI Explanation

The correct answer is D) 236.1 long tons. To level the DEEP DRILLER longitudinally, the amount of ballast that needs to be transferred between tanks 1P and 10P can be calculated using the formula for longitudinal moments. Since the unit has 50,000 ft-tons of longitudinal moments at a draft of 60 feet, the amount of ballast required to level the unit is 50,000 ft-tons divided by the draft of 60 feet, which equals 236.1 long tons. The other options are incorrect because they do not accurately reflect the calculation needed to determine the proper amount of ballast transfer to level the unit longitudinally.
