AN ANCHOR-HANDLING SYSTEM FOR DRILL SHIP USE
The Author describes an 8-line anchor-handling system for drillships provided by Appleton Marine. The most important factor in the design of such a system is precise control of the chain tension during pay-out. Too much anchor-windlass braking will slow the assisting workboat, and too little will cause the anchor chain to pile up on the sea bed. The Appleton system enables controlled payout of 3,000 ft of 3 1/8-in Stud Link Chain to be accomplished in 2-4 minutes. The time for setting and tensioning the eight anchors would be less than 6 hours.
