Support buoys are produced from closed cell EVA/PE resilient foam, sprayed with self-colored polyurethane elastomer skin, is a kind of general surface support buoys for offshore mooring buoys system. They are widely used as the warning buoys for ships, vessels, barges and boats as well as marines docking & berthing. Support Buoys are normally classified into pick up buoys, chain through buoys, cylindrical buoys, anchor pendant buoys and mooring buoys etc.
Support Buoys Construction
- Closed cell resilient foam core, unsinkable design
Cylindrical chain support foam buoys are manufactured with high density closed-cell PE/EVA resilient foam core. This resilient foam ensure buoys self fendering with high impact absorption capacity, even the polyurethane elastomer skin punctured, cylindrical chain support foam buoys will be unsinkable without absorbing any water.
- Tough reinforced Nylon Layer

Support Mooring Buoys
Each cylindrical chain support foam buoy is constructed of polyurethane elastomer reinforced with nylon filament layer. The polyurethane skin is unique elastomer especially for offshore & subsea applications. The elastomer skin is high resistance to abrasion, fatigue and ultra violet degradation and significantly much more durable.
- Excellent end steel works
There is a central tube encased in the closed-cell urethane foam central body of cylindrical chain support foam buoys. The central tube is either epoxy coated or hot-dipped galvanized, with longitudinal gussets and extend load distribution flanges at each end. Optional accessories like bail eye, clevis eye, swivel, chain locking plate, single locking pin end fitting etc.
