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.
Polyurethane elastomer skin with 3~10mm thickness
High impact absorption capacity
Unskinable closed cell rigid foam core, never absorp water even PU outer skin punched
Various end fitting options available, swivel ends, pad-eye, crucifix
For better support and balance
Reinforced nylon filament ensures polyurethane elastomer protective coating has higher tear strength
Cylindrical foam-filled chain support buoys ranging from 1 Ton to 4 Tons (or more) – Fitted on each end with mooring pad eye or swivel or mixed depending on use.
