Chain Support Cylindrical Utility Buoys

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

General surface 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 ultraviolet ray degradation. For the extreme service environment, the polyurethane elastomer skin can be reinforced by nylon to protective coating with higher tear strength, making the buoy long-lasting and virtually maintenance-free.

Chain Support Utility Buoys Features

Chain support utility buoys have significant advantages, lier easier to handle, better corrosion resistance, low maintenance, never sink or burst, self-fendering that withstands vessel impact.

PU Protective Outer Skin – Reinforced urethane elastomer skin
Self-fendering – High impact absorption capacity
Inner Foam – Unskinable closed-cell rigid foam core
Upper-End Fitting – Various end fitting options available
Internal Steel Core – For better support and balance
Lower End Fitting – Mooring eye used for anchor connecting

Consctruction of Chain Support Utility Buoys

General suface chain support cylindrical utility buoys are manufactured with high quality closed-cell PE/EVA resilient foam, encapsulated with self-colored tough polyurethane elastomer skin.

Tough reinforce polyurethane outer skin – General surface support buoy’s skin is constructed of polyurethane elastomer, which also can be reinforced with nylon filament. The polyurethane skin is unique elastomer specifically for offshore applications. It is high resistance to abrasion, fatigue and ultra voilet degradation and is significantly more durable.
Laminated closed cell resilient foam core, unsdinkable design – General sruface support buoys are made with highest quality closed-cell PE/EVA foam. This resilient foam make the buoys self fendering with high imptact absorption capacity. Even the skin was puntured, it also is unsinkable without absrbing water. With our unique laminating proecess, each foam core is integrity. The foam core cannot be reputured after long time sevice.
Steel work and end assembly – Through central steel tube with longtitudinal guessets and external load distribution flanges at each end, epoxy coated or hot-dipped galvanized, are encased in a closed-cell urethane foam central body. Opetional bail eye, clevis eye, swivel, chain locking plate, single locking pin end fitting are availble.
