Product Description
1. A Brief Introduction: 

Subsea eva foam buoyancy 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 Buoy, Chain-Throught Buoy, Pick-Up Buoy(YT-PUB). 

Here below we will introduce the details of pick up buoy(YT-PUB)

2. Usage: 

General purpose pick-up buoy is sued for mooring, marker and pick-up duties. 

3. Constructions: 
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. 

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 buoy. 
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.
