The DEEP DRILLER is loaded as shown is Sample Load Form #4 (Drilling). What would be the change in vertical moments for Fresh Water if the entire contents of Drill Water Tank 5P are transferred to Drill Water Tank 5S?

Correct Answer: Option B — 2,689 ft-tons

Vertical moment changes are calculated by multiplying transferred fluid weight by its vertical distance. Transferring drill water between tanks 5P and 5S on the DEEP DRILLER involves vertical center changes specified in the tank capacity tables, resulting in a moment change of 2,689 ft-tons.
