Deck General USCG Question #4277 (Set 137)

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 draft?

Official USCG Answer & Rule Citation

Correct Answer: Option D — 56 feet 10.9 inches

Removing heavy liquid weights like liquid mud from a MODU decreases displacement and draft. Utilizing the vessel's specific tank capacity and hydrostatic tables from Sample Load Form #3, discharging all liquid mud reduces the operational draft to 56 feet 10.9 inches.
