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 _______________.
AI Explanation
The correct answer is C) 7.0 seconds.
The pitch period of a floating platform is related to the water depth and the platform's pitch angle. In 150 feet of water depth, with a pitch angle of 1 degree, the platform's pitch period should be longer than 7.0 seconds. This is based on the relationship between water depth, pitch angle, and platform motion, which is a key consideration in the stability and safety of offshore platforms.
The other options are incorrect because:
A) 0.2 second is too short for the given water depth and pitch angle.
B) 3.2 seconds is too short for the given water depth and pitch angle.
D) 9.2 seconds is longer than the required minimum of 7.0 seconds.
