In storm conditions in 600 feet of water, completely slacking the leeward mooring line of the DEEP DRILLER reduces the tension in that line to about __________.

Correct Answer: Option B — 50 kips

When heavy weather forces require shedding mooring restraint, slacking a leeward line in 600 feet of water drops its residual tension drastically. The remaining line tension stabilizes at approximately 50 kips due to catenary weight and catenary friction against the seabed.
