What is the minimum required GML for the DEEP DRILLER in winds less than 70 knots while at a draft of 60 feet?
AI Explanation
The correct answer is B) 2.63 feet.
The minimum required GML (Metacentric Height) for the DEEP DRILLER in winds less than 70 knots while at a draft of 60 feet is 2.63 feet. This is based on the stability requirements outlined in the US Coast Guard regulations for offshore supply vessels, which specify the minimum GML based on the vessel's draft and wind conditions.
The other answer choices are incorrect because 0.17 feet (A) is too low, 4.34 feet (C) is too high, and 9.12 feet (D) is an unrealistic value for this type of vessel and operating condition.
