During the passage of a severe storm, the DEEP DRILLER is at survival draft. Strong winds are blowing from the starboard. A careful load form calculation determined that, although the unit is level, the TCG is 2.0 feet to starboard. The value of the wind heeling moment is __________.

Correct Answer: Option B — 32,099 ft-long tons
Wind heeling moment is calculated using the transverse windage area, lateral center of effort, and wind pressure. With a transverse center of gravity (TCG) offset of 2.0 feet to starboard at survival draft, the resulting wind heeling moment evaluates mathematically to 32,099 ft-long tons.
