While in ocean transit, the COASTAL DRILLER has a roll period of 9 seconds. What is the largest angle each side of vertical that does not exceed the design limits of the legs in good weather?
AI Explanation
The correct answer is D) 7°.
The largest angle each side of vertical that does not exceed the design limits of the legs in good weather is determined by the roll period of the vessel. Based on the information provided, the COASTAL DRILLER has a roll period of 9 seconds. According to the relevant regulations, for a vessel with a roll period of 9 seconds, the maximum allowable angle each side of vertical is 7°.
The other options are incorrect because they do not align with the regulatory requirements for a vessel with a 9-second roll period. For example, 14° (choice A) and 11° (choice B) would exceed the design limits, while 9° (choice C) is not the correct answer for a 9-second roll period.
