What is the change in longitudinal 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 -4,708 ft-kips
D -20,052 ft-kips
AI Explanation

The correct answer is D) -20,052 ft-kips. Explanation: When 2.5 feet of drill water is discharged from drill water tank 23, it results in a decrease in the longitudinal moment of the Coastal Driller. The decrease in longitudinal moment is calculated based on the change in weight and the distance of the tank from the vessel's longitudinal center of gravity. In this case, the discharge of 2.5 feet of drill water from tank 23 would result in a longitudinal moment decrease of -20,052 ft-kips. The other answer choices are incorrect because they do not accurately reflect the change in longitudinal moment due to the specified discharge of drill water.
