While the COASTAL DRILLER is in normal transit, the roll period is 8 seconds. What would be the limiting angle of pitch which does not exceed the design limits of the legs?
AI Explanation
The correct answer is C) 6°.
The limiting angle of pitch that does not exceed the design limits of the legs is determined by the roll period of the vessel. When the roll period is 8 seconds, the limiting angle of pitch should not exceed 6° to stay within the design limits of the legs.
The other options are incorrect because 10° (A) and 8° (B) would exceed the design limits, while 4° (D) would be too conservative and not fully utilize the capabilities of the vessel.
