What is the change in longitudinal moments for the Coastal Driller if 2.0 feet of drill water is transferred from a full drill water tank 23 to an empty drill water tank 6?
AI Explanation
The correct answer is B) 7,990 foot-kips decrease.
When 2.0 feet of drill water is transferred from a full drill water tank 23 to an empty drill water tank 6, the longitudinal moment decreases by 7,990 foot-kips. This is because moving weight from a higher point on the vessel to a lower point reduces the overall longitudinal moment acting on the vessel.
The other options are incorrect because they do not accurately reflect the change in longitudinal moment resulting from this weight transfer. Option A would indicate an increase in longitudinal moment, which is the opposite of what occurs. Options C and D overstate the magnitude of the decrease in longitudinal moment.
