The DEEP DRILLER is loaded as shown in the Sample Load Form #3 (Preparing to Drill). If the liquid mud in mud pit #1 (see table 8) is dumped, what would be the new draft?

Correct Answer: Option C — 59 feet 2.7 inches

Removing weight from a vessel decreases its displacement, resulting in a lighter mean draft. Applying the specific hydrostatic particulars and vertical center of gravity changes from Sample Load Form #3 yields a new calculated draft of 59 feet 2.7 inches.
