While anchored in 600 feet water depth, 3,150 feet of chain is deployed for line #8. Tension on that line is 220 kips. According to the DEEP DRILLER Operating manual, how much of that chain lies along the bottom?

Correct Answer: Option B — 1,422 feet

Using the DEEP DRILLER operating manual catenary tables for a 600-foot water depth and 220 kips tension, the mathematical distribution of the deployed 3,150-foot chain results in exactly 1,422 feet resting horizontally along the seabed.
