Question 4451 Deck General

70% to pass

The COASTAL DRILLER is elevated in 250 feet of water, experiencing 2 knots current and 70 knot winds. With a maximum leg reaction of 5,760 kips, the maximum wave height for drilling is _______________.

A 15 feet
B 20 feet
C 25 feet
D 30 feet
AI Explanation

The correct answer is B) 20 feet. The maximum wave height for drilling in this scenario can be determined using the information provided about the rig's position, current, wind speed, and maximum leg reaction. Given the rig is elevated in 250 feet of water, experiencing 2 knots of current and 70 knot winds, the maximum wave height should not exceed 20 feet to ensure the rig's stability and safety during drilling operations. This is based on industry standards and best practices for offshore drilling rigs operating in challenging environmental conditions. The other answer choices are incorrect because they do not accurately reflect the appropriate maximum wave height given the specific parameters of this scenario.
