The COASTAL DRILLER, elevated in 200 feet of water,... - USCG Deck General

The COASTAL DRILLER, elevated in 200 feet of water, has two knots of current and 70 knot winds. With a maximum leg reaction of 5,840 kips, the maximum wave height for drilling is _______________.

A 20 feet

B 30 feet

C 35 feet

D 40 feet

AI Explanation

The correct answer is A) 20 feet. The maximum wave height for drilling is determined by the maximum leg reaction of the offshore platform, which in this case is 5,840 kips. Given the water depth of 200 feet, current of 2 knots, and wind speed of 70 knots, the maximum wave height that the platform can safely withstand is 20 feet. The other options are incorrect because they exceed the maximum leg reaction capacity of the platform. A wave height of 30 feet, 35 feet, or 40 feet would likely exceed the structural limits of the platform and put it at risk of failure during drilling operations.
