What is the increase in transverse free surface 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) 3,914 foot-kips.
The increase in transverse free surface moments is determined by the weight of the transferred liquid and the distance between the centers of gravity of the two tanks. In this case, transferring 2.0 feet of drill water from a full tank 23 to an empty tank 6 results in an increase of 3,914 foot-kips in the transverse free surface moment.
The other options are incorrect because they do not accurately reflect the calculation based on the given information. Option A is too high, Option C is too low, and Option D is significantly underestimated.
