Various Colors EVA Foam Offshore Surface Support Cylindrical Buoys with Polyethylene Skin
General surface chain support buoys are extensively used in single-point mooring (SPM) systems. These specialized buoys include cylindrical buoys, chain-through buoys, and pick-up buoys designed for various marine applications.
Constructed with resilient closed-cell polyethylene/EVA foam around the inner central steelwork and covered by a polyurethane (PU) outer skin, these buoys offer exceptional durability. The closed-cell foam core ensures self-fendering and unsinkable performance even in case of damage. The self-colored polyurethane elastomer skin provides excellent resistance to abrasion and UV degradation. For extreme service environments, the polyurethane elastomer skin can be reinforced with nylon to enhance tear strength, resulting in long-lasting, virtually maintenance-free operation.
Key Features
PU Protective Outer Skin (Polyurethane elastomer skin with 3~10mm thickness)
Self-fendering (High impact absorption capacity)
Inner Polyethylene Foam (Unsinkable closed cell rigid foam core, never absorbs water even if PU outer skin is damaged)
Upper End Fitting (Various end fitting options available: swivel ends, pad-eye, crucifix)
Internal Steel Core (For superior support and balance)
Reinforcement Layer (Reinforced nylon filament ensures polyurethane elastomer protective coating has higher tear strength)

Various End Fittings
