What is the change in transverse moments for the Coastal Driller if 2.5 feet of drill water is discharged from drill water tank 23?

A 1,671 ft-kips
B -161 ft-kips
C -1,800 ft-kips
D -2,982 ft-kips
AI Explanation

The correct answer is A) 1,671 ft-kips. Discharging 2.5 feet of drill water from tank 23 would decrease the vessel's transverse moment by the weight of the discharged water multiplied by the transverse distance from the vessel's centerline to the tank's center of gravity. This reduction in transverse moment would be 1,671 ft-kips. The other answer choices are incorrect because they do not accurately reflect the change in transverse moment due to the specified discharge. Options B, C, and D provide incorrect values that do not match the expected change in transverse moment for this scenario.
