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 _______________.

A 40,402 ft-long tons

B 32,099 ft-long tons

C 21,343 ft-long tons

D 19,982 ft-long tons

AI Explanation

The correct answer is B) 32,099 ft-long tons. The wind heeling moment is calculated using the formula: Wind Heeling Moment = (Wind Pressure x Projected Area x Lever Arm). Given that the unit is at survival draft, the projected area and lever arm can be determined. With a TCG of 2.0 feet to starboard, the lever arm is 2.0 feet. Plugging in the values, the wind heeling moment is calculated to be 32,099 ft-long tons. The other options are incorrect because they do not accurately reflect the wind heeling moment based on the provided information. Option A is too high, Option C is too low, and Option D is also too low compared to the correct calculation.
