Ball Shape EVA Filled Marine Mooring Buoy

General surface support buoys are entensively used in single point mooring (SPM) system. The three main type are as below:

1. Cylindrical Buoys.

2. Chain thought Buoys.

3. Pick-up Buoys.

Evergreen General Marine Foam Buoys are manufactured from a polyethylene or EVA 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.

Construction Features:

Core

The core is manufactured by batching up the resilient closed cell polyethylene or EVA 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.

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

Comprising through central steel tube with longitudinal gussets and external load distribution flanges at each end. A swivel assembly, certified 10 tonnes SWL, with bows at each end passes through the central tube. 
All the material of swivel assembly are hot dip galvanized. Steelwork to be coal tar epoxy painted.
