The DEEP DRILLER is loaded as shown in the Sample Load Form #3 (Preparing to Drill). If all the liquid mud (see table 8) is dumped, what would be the new height of the longitudinal metacenter?

Correct Answer: Option B — 61.19 feet

The height of the longitudinal metacenter above the keel depends strictly on draft and waterplane inertia. Dumping all liquid mud changes the vessel's draft, and referencing the DEEP DRILLER hydrostatic particulars for the resulting lighter draft gives a new KML of 61.19 feet.
