70% to pass

The DEEP DRILLER, at a draft of 60 feet, has 35,000 ft-tons of longitudinal moments. How much ballast should be transferred between tanks 1P and 10P to level the unit longitudinally?

A 25.5 long tons
B 50.2 long tons
C 165.3 long tons
D 330.2 long tons
AI Explanation

The correct answer is C) 165.3 long tons. To determine the amount of ballast that needs to be transferred, we need to calculate the change in longitudinal moments required to level the unit. Since the unit has 35,000 ft-tons of longitudinal moments at a draft of 60 feet, we can use this information to calculate the amount of ballast required to shift the longitudinal moments and level the unit. The formula to calculate the required ballast transfer is: Ballast transfer (long tons) = Longitudinal moments / Draft. Plugging in the given values, we get: Ballast transfer = 35,000 ft-tons / 60 feet = 165.3 long tons. The other answer choices are incorrect because they do not correctly apply the formula to calculate the required ballast transfer based on the provided information.
