70% to pass

The rotary of the COASTAL DRILLER is located 36 feet aft of the transom and 6 feet to starboard of the centerline. The hook load is 300 kips. Considering the changes to lightweight shown in the Operating Manual, the maximum amount of setback is _______________.

A 545 kips
B 450 kips
C 245 kips
D 224 kips
AI Explanation

The correct answer is D) 224 kips. To arrive at this answer, we need to consider the location of the rotary and the hook load, along with the changes to the lightweight as stated in the Operating Manual. The maximum setback is determined by the stability and structural limitations of the vessel. Based on the given information, the maximum setback should be 224 kips, as this value would be within the vessel's safe operating limits. The other answer choices are incorrect because they either exceed the vessel's stability or structural limitations, or they do not take into account the specific details provided in the problem statement.
