Question 4290Deck General70% to pass
While going on location in 200 feet water depth when the roll angle of the COASTAL DRILLER is 2.5 degrees, the roll period should be longer than _______________.
AI Explanation
The correct answer is C) 13.0 seconds.
The reasoning is based on the relationship between the roll period and the water depth. In deeper water, the roll period of a vessel increases. With a water depth of 200 feet and a roll angle of 2.5 degrees, the roll period should be longer than 13.0 seconds, as per the principles of naval architecture and ship stability.
The other options are incorrect because: A) 0.8 second is too short for a vessel in 200 feet of water depth, B) 6.2 seconds is also too short, and D) 17.0 seconds, while a possible answer, is not the most appropriate choice given the provided information.
