Question 3445 Deck General

The correct answer is B) increased overturning moments. Using air gaps in excess of the stated Limits of Elevated Service for the COASTAL DRILLER would increase the exposed area of the vessel above the water, resulting in greater overturning moments acting on the structure. This can compromise the stability and safety of the vessel, as the increased overturning forces can make the structure more susceptible to capsizing or other stability-related failures. The other options are incorrect because: A) Increased air gaps would not necessarily increase static leg loading. C) Reduced exposed area is the opposite of what would occur with excessive air gaps. D) The hull being in the storm wave zone is not directly related to the issue of excessive air gaps.
