While going on location in 250 feet water depth when the pitch angle of the COASTAL DRILLER is 2 degrees, the single amplitude pitch period should be longer than __________.

Correct Answer: Option D — 13.9 seconds

MODU operational manuals and hydrodynamic stability criteria calculate limiting motion thresholds; using standard dynamic formulas for wave-induced motions in specific water depths establishes the minimum allowable pitch period of 13.9 seconds for safety.
