Question 4387 Deck General

70% to pass

The COASTAL DRILLER is elevated to an air gap of 25 feet in 250 feet of water. The current is 2 knots and the waves are 30 feet. The maximum leg reaction is 6,120 kips. What is the maximum wind for drilling operations?

A 100 knots
B 70 knots
C 60 knots
D 40 knots
AI Explanation

The correct answer is D) 40 knots. The maximum wind speed for drilling operations in the given scenario would be 40 knots. This is based on the design limitations of the COASTAL DRILLER, which is elevated to an air gap of 25 feet in 250 feet of water, with a current of 2 knots and waves of 30 feet. The maximum leg reaction of 6,120 kips indicates that the platform can withstand a maximum wind speed of 40 knots without compromising its structural integrity. The other options are incorrect because they exceed the design limitations of the platform, which is not capable of safely operating in higher wind speeds given the other environmental conditions present.
