While in 150 feet water depth when the pitch angle of the COASTAL DRILLER is 1 degree, the platform pitch period for going on location should be longer than __________.

Correct Answer: Option C — 7.0 seconds

Rig operating manuals specify minimum pitch periods to avoid resonance and critical dynamic amplification during preload or location operations. In 150 feet of water, a pitch period exceeding 7.0 seconds is required to maintain safe motion limits and structural integrity.
