Product Description
Offshore Buoys

1. Offshore Buoys are manufactured from a polyethylene thermo-laminated foam core encapsulated within self-colored polyurethane out skin. Used extensively in single point mooring (SPM) systems, the three main types of support buoy are: Cylindrical Buoys, Chain-Throught Buoys, Pick-Up Buoys.

2. Construction Features:

2-1
Closed-Cell Foam Core

The core is manufactured by batching up the resilient closed cell polyethylene closed cell foam and uniformly and continuously thermolaminating each layer together. The method ensures a bond stronger than the foam itself and eliminates the use of adhesives which can break down under long use. Useing of a polyethylene foam core ensure the buoy will not absorb water even if the skin is punctured, increasing the lifespan of the product and reducing maintenance costs. The resilient material makes the buys self fendering with a high impact absorption capacity.

2-2
PU-Skin

The core is encapsulated with a skin of high performance polyurethane elastomer, spray applied. Polyurethane elastomer is selected for the skin because of its high resistance to abrasion, fatigue and ultra violet degradation and is significantly more durable than polyethylene materials used in the construction of rotationally moulded buoys.
Steelwok and end assembly
