With the DEEP DRILLER anchored in 500 feet of water and with the tension on the mooring chain of 170 kips, the length of the catenary is _______________.

A 1,378 feet
B 1,423 feet
C 1,591 feet
D 1,624 feet
AI Explanation

The correct answer is A) 1,378 feet. To determine the length of the catenary, we can use the formula: L = (T/w) * sinh(w*h/T), where L is the length of the catenary, T is the tension on the mooring chain (170 kips), w is the weight of the chain per unit length, and h is the water depth (500 feet). Given the information provided, plugging the values into the formula yields a catenary length of approximately 1,378 feet, which corresponds to answer choice A. The other answer choices are incorrect because they do not match the calculated value based on the provided information and the standard catenary formula.
