For the DEEP DRILLER, in deballasting to survival draft when threatened with heavy weather from 100 knot winds, a load form should be calculated to determine that __________.

Correct Answer: Option D — KG corrected for free surface effects does not exceed 62.09 feet

Stability compliance under 46 CFR requires strict adherence to maximum allowable vertical center of gravity (KG) limits. When deballasting for heavy weather, calculations must verify that the free surface corrected KG does not exceed the structural limit of 62.09 feet to maintain positive intact stability.
