What is the increase in transverse 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?

Correct Answer: Option A — 4783 foot-kips

Transverse moment alterations depend on the transverse distances between tank centroids. Transferring 2.0 feet of drill water from tank 23 to tank 6 generates an increase in transverse moments of 4783 foot-kips, verified via the MODU's stability booklet and tank sounding tables.
