Question 4282Deck General70% to pass
The COASTAL DRILLER, elevated in 200 feet of water with 2 knots current, 30 foot waves, and wind speeds of 60 knots may continue drilling if the maximum leg reaction is less than _______________.
AI Explanation
The correct answer is C) 5,870 kips.
The key factor in this question is the maximum leg reaction, which refers to the maximum force exerted on the legs or supports of the offshore drilling platform. Based on the given conditions of 200 feet of water depth, 2 knots of current, 30-foot waves, and 60-knot winds, the maximum leg reaction should not exceed 5,870 kips (1 kip = 1,000 pounds-force) for the COASTAL DRILLER to continue drilling operations safely.
The other options are incorrect because they do not match the specific limit for the maximum leg reaction under the given environmental conditions. Option A (5,700 kips) is too low, while options B (5,790 kips) and D (5,990 kips) are too high compared to the correct answer of 5,870 kips.
