Question 4900 Deck General

The correct answer is B) 875 kips. The placement of the rotary 34 feet aft of the transom and 2 feet to starboard of the centerline on the COASTAL DRILLER limits the maximum hook load to 875 kips. This is based on the stability and loading requirements for offshore supply vessels, which dictate the maximum allowable hook load based on the location of the rotary relative to the vessel's center of gravity and other key dimensions. The other options are incorrect because they do not align with the standard stability and loading requirements for this type of vessel configuration. For example, 1000 kips (A) would exceed the safe operating limits, while 750 kips (C) and 450 kips (D) would be unnecessarily conservative for this particular setup.
