HIGH SEAS OIL CONTAINMENT BARRIER MOORING SYSTEM
The mooring system was designed, fabricated and tested to moor the Air Deployable Lightweight High Seas Oil Containment Barrier, a component of the U.S. Coast Guard's High Seas Oil Spill Response Systems. The key criteria to which the mooring system was built are: (1) deliverable by HH-3 helicopter, (2) holding capacity of 8,500 pounds with 1,000 pound nominal load, (3) capability of obtaining a mooring scope of 2:1 to 3:1 in water depths of 25 to 200 feet. The system consists of an inflatable buoy, 500-pound STATO anchor, 550 feet of 7/8 diameter polyurthane-jacketed nylon line and 45 feet of 3/4 inch chain, and a delivery container. Once the mooring system has been delivered to the site by the helicopter, a small boat tows it to the location and activates the system. The delivery container is recovered by a buoy tender once the system has been deployed. Computer methods were used to size the anchor and mooring line segments that are used to construct a mooring of desired length and scope. Anchor holding power and operational sequence tests were conducted. The system weighs 2,350 pounds and has a delivery radius of 70 nautical miles as external cargo under an HH-3 helicopter. (Author)
