The DEEP DRILLER is observed to be level at a draft of 60.0 feet. At the same time, the calculated load form shows the displacement to be 17,845 long tons, total longitudinal moments 51,466 foot-tons, and total transverse moments -10,000 foot-tons. What is the weight of the missing load?
Official USCG Answer & Rule Citation
Correct Answer: Option D — 272.7 long tons
Displacement discrepancies in a known trim and draft condition are resolved by comparing hydrostatic weight tables against calculated totals. The remaining unaccounted weight required to bring the mobile offshore drilling unit to equilibrium is 272.7 long tons.
