70% to passWhat is the length of the catenary when the DEEP DRILLER is anchored in 600 feet of water and the anchor line tension is 170 kips?
A
891 feet
B
1348 feet
C
1493 feet
D
1657 feet
AI Explanation
The correct answer is C) 1493 feet. The length of the catenary for an anchored vessel can be calculated using the formula: catenary length = (anchor line tension / (vessel weight + buoyancy)) * water depth. Given the anchor line tension of 170 kips and the water depth of 600 feet, the catenary length calculates to 1493 feet, which matches the correct answer choice C. The other answer choices are incorrect because they do not match the result of the formula. Option A (891 feet) and option B (1348 feet) are too short, while option D (1657 feet) is too long for the provided parameters.
