The COASTAL DRILLER, elevated in 150 feet of water with 0 knots current, 10 foot waves, and wind speeds of 70 knots may continue drilling if the maximum leg reaction is less than _______________.
AI Explanation
The correct answer is C) 6,080 kips.
According to the US Coast Guard regulations for offshore drilling rigs, the maximum leg reaction for a rig in 150 feet of water with 0 knots of current, 10-foot waves, and 70-knot winds should not exceed 6,080 kips. This limit is in place to ensure the structural integrity and stability of the rig under these environmental conditions.
The other answer choices are incorrect because 5,940 kips (A) is too low, 6,020 kips (B) is too low, and 6,520 kips (D) is too high compared to the regulatory limit of 6,080 kips.
