70% to pass

In a combination chain and wire rope mooring system, the anchor chain is deployed at the anchor end of the line to _______________.

A increase the holding power
B reduce the catenary
C increase fatigue life of the system
D reduce the time to retrieve the line
AI Explanation

You are correct, the answer is A) increase the holding power. The anchor chain is deployed at the anchor end of the line in a combination chain and wire rope mooring system to increase the holding power of the mooring. The weight and increased friction of the anchor chain on the seafloor creates additional resistance and holding power compared to using just the wire rope alone. The other options are incorrect because: B) reducing the catenary would not be the purpose of using the anchor chain, C) increasing fatigue life is not the primary reason, and D) reducing retrieval time is also not the main purpose of the anchor chain in this system.
