70% to pass

In using the Allowable Wind and Wave Charts for the COASTAL DRILLER, leg penetration is assumed to be less than _______________.

A 55 feet
B 45 feet
C 35 feet
D 25 feet
AI Explanation

The correct answer is D) 25 feet. The Allowable Wind and Wave Charts for the COASTAL DRILLER assume a leg penetration of less than 25 feet. This is a key parameter in determining the maximum allowable wind and wave conditions for safe operation of this type of vessel. Leg penetration beyond 25 feet would require different wind and wave limits to ensure the stability and structural integrity of the vessel. The other options (A, B, C) are incorrect because they do not match the 25-foot leg penetration assumption used in the Allowable Wind and Wave Charts for the COASTAL DRILLER.
