General surface chain support buoys are extensively used in single-point mooring (SPM) systems. The chain support buoys include cylindrical buoys, chain-through buoys, and pick-up buoys.

General surface chain support buoys are constructed by resilient closed cell polyethylene /EVA foam around the inner central steelwork, covered by polyurethane (PU) outer kin. The resilient closed cell polyethylene/EVA foam core guarantees self-fendering and unsinkable even in case of damage. And self-colored polyurethane elastomer skin is resistant to abrasion and ultra violet rays degradation. For extreme service environment, the polyurethane elastomer skin can be reinforced by nylon to protective coating has higher tear strength, making the buoy long lasting and virtually maintenance free.

The mooring buoys can be installed with various fittings on the top. And the mooring buoys can be designed to meet different requests. It has the same design as common mooring buoys.

The large mooring tube with 82.5mm ID will accept mooring chain of up to 20mm in diameter. The mooring tube is not molded into the buoy but slides into a tubular section that runs down the center of the buoy enabling the tube to be replaced at any stage during the product's service life.

Customized size are available upon request.

1. Resilient out foam (available upon request)
2. Rigid inner foam
3. Internal steel core
4. Load distribution plates
5. Lower end fitting (mooring eye shown)
6. Reinforced urethane elastomer skin
