70% to pass

Use of air gaps in excess of that stated in the Limits of Elevated Service for the COASTAL DRILLER could result in _______________.

A the hull being in the storm wave zone
B reduced exposed area
C increased overturning moments
D increased static leg loading
AI Explanation

The correct answer is C) increased overturning moments. When the air gap (the distance between the waterline and the underside of the deck) on a vessel like the COASTAL DRILLER is increased beyond the limits specified, it can result in increased overturning moments. This means the vessel becomes more susceptible to tipping or capsizing due to the higher center of gravity and increased forces acting on the structure. The other answer choices are incorrect - increased air gap does not directly result in the hull being in the storm wave zone, reduced exposed area, or increased static leg loading.
