About this file
This is a technical data sheet specifying buoy chain requirements for mooring applications. Buoy chain connects buoys to sinkers and must comply with G-SEC Drawing No. 121032, G-SEC Specification No. 377, and the MOORSEL (Computer Aided Mooring Selection Guide) computer system. All chains must maintain an overall length of 90 feet (27.4 meters) with a tolerance of ±3%.
The document provides comprehensive specifications for eleven chain sizes ranging from 1/2 inch to 2-1/4 inches in common link diameter. For each size, it details specific dimensions for common links and end links (labeled A through F), along with critical physical values including proof load, break load, dry weight per foot, and total dry shot weight. For example, 1/2-inch chain has a proof load of 7,500 lbs and break load of 15,000 lbs, while 2-1/4-inch chain has a proof load of 147,000 lbs and break load of 294,000 lbs. The document notes that end links are currently provided only on 1/2-inch chain, and that 7/8-inch and 1-5/8-inch chain sizes are no longer manufactured but their dimensions are retained for reference purposes. All specifications reference the latest revisions of the supporting technical documents.
