While in 150 feet water depth when the pitch angle of the COASTAL DRILLER is 2 degrees, the platform roll period for going on location should be longer than __________.

Correct Answer: Option C — 10.0 seconds

Dynamic amplification and wave resonance criteria during location installation require controlled natural roll periods. In 150 feet of water with a 2-degree pitch, operating limitations dictate that the platform roll period must exceed 10.0 seconds to ensure safe leg-lowering operations.
