Question 4439Deck General70% to pass
The COASTAL DRILLER is elevated in 192 feet of water. Leg penetration is 83 feet. The maximum leg reaction is 5,940 kips. The waves are 30 feet and the current is 2 knots. What is the maximum wind for drilling?
AI Explanation
The correct answer is B) 50 knots.
The maximum wind for drilling is determined by the environmental conditions, including wave height and current, as well as the rig's structural capacity. Given the information provided, the maximum leg reaction of 5,940 kips and the wave height of 30 feet, the maximum wind speed for safe drilling operations is 50 knots, as per industry standards and best practices.
The other options are incorrect because they do not accurately reflect the maximum wind speed based on the provided environmental conditions and the rig's structural limitations. Option A (45 knots) is too low, while options C (57 knots) and D (62 knots) are too high and would exceed the rig's safe operating limits.
