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 longitudinal location of the missing load?
Official USCG Answer & Rule Citation
Correct Answer: Option C — -40.57 feet
Applying static equilibrium equations, the longitudinal moment discrepancy between observed draft conditions and calculated hydrostatic summaries isolates the missing load's position. Dividing the longitudinal moment error by the missing weight yields -40.57 feet.
