What is the change in longitudinal moments for the DEEP DRILLER if 103.48 long-tons of ballast is transferred from a full ballast tank 1P to an empty ballast tank 10S?

A 21,913 foot-tons decrease
B 13,414 foot-tons decrease
C 10,944 foot-tons decrease
D 6,707 foot-tons decrease
AI Explanation

The correct answer is A) 21,913 foot-tons decrease. The change in longitudinal moments when transferring 103.48 long-tons of ballast from a full ballast tank 1P to an empty ballast tank 10S on the DEEP DRILLER would result in a 21,913 foot-tons decrease. This is because the longitudinal moment is calculated by multiplying the weight of the ballast (103.48 long-tons) by the distance between the two tanks (the moment arm). The longer the moment arm, the greater the change in longitudinal moment. The other options are incorrect because they do not accurately reflect the change in longitudinal moment based on the given information about the weight and location of the ballast transfer.
