About this file
This is a technical data sheet specifying buoy chain requirements for mooring systems. The buoy chain serves to connect buoys to sinkers and must conform to G-SEC Drawing No. 121032, G-SEC Specification No. 377, and the MOORSEL (Computer Aided Mooring Selection Guide) standards. The chain has an overall length of 90 feet (27.4 meters) with a tolerance of ±3 percent.
The specification provides detailed dimensional and physical performance data for chain sizes ranging from 1/2 inch to 2-1/4 inches in diameter. Each size specifies common link and end link dimensions (labeled A through F), along with critical performance metrics including proof load, break load, weight per foot (dry), and total dry shot weight. Proof loads range from 7,500 lbs for 1/2-inch chain to 147,000 lbs for 2-1/4-inch chain, while break loads are approximately double the proof load values. The document notes that end links are currently supplied only on 1/2-inch chain, and that 7/8-inch and 1-5/8-inch chain sizes are no longer manufactured, though their specifications are retained for reference purposes.
