Good Quality and Price EVA Foam Floating Marine Navigation 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.

Material: Swivel assembly: bows to BS970
Gusets, flanges carbon steel to BS EN10025 Fe 430 A or B
Central tube to BS 6323 Pt 3 HFS 5
Finish: Swivel assembly hot dip galvanized to BS 729 Zn2/Zn4 at 610 g/m2
Steelwok to be coal tar epoxy painted
Skin Colour: Orange, Yellow and others

Subsea Buoyancy

Evergreen can make buoyancy material used for subsea up to 7000m. Product of different opplications buoyancys are manufactured upon our advance subsea buoyancy material. Wecan make subsurface mooring buoys , cable float, pipeline buoys, ROV buoyancy module, special buoys, and other synmatic foam products.

Our high-performance subsea buoyancy material and synmatic foam have the following performance.
