Surface Support Buoys

General surface support buoys are extensively used in single point mooring (SPM) system. The three main types are cylindrical buoys, chain-through buoys and pick-up buoys.
Construction of General Surface Support Buoys
Evergreen Maritime general surface support buoys are manufactured with high quality closed-cell PE/EVA resilient foam, encapsulated with self-coloured tough polyurethane elastomer skin.

A. Laminated closed cell resilient foam core, unsinkable design

General surface support buoys are made with highest quality closed-cel PE/EVA foam. This resilient foam make the buoys self fendering with high impact absorption capacity. Even the skin was punctured, it also is unsinkable without absorbing water. With our unique laminating process, each foam core is integrity. The foam core cannot be ruptured after long time service.

B. Tough nylon filament reinforced polyurethane skin

General surface support buoys' skin is constructed of polyurethane elastomer which is reinforced with nylon filament. The polyurethane skin is unique elastomer specifically for offshore applications. It is high resistance to abrasion, fatigue and ultra violet degradation and is significantly more durable.

C. Steel work and end assembly

Through central steel tube with longitudinal gussets and external load distribution flanges at each end, epoxy coated or hot-dipped galvanized, are encased in a closed-cell urethane foam central body. Optional bail eye, clevis eye, swivel, chain locking plate, single locking pin end fitting are available.

Anchor Pendant Buoys

Evergreen Anchor Pendant Buoys are available in a wide range of sizes, can be supplied in suitcase, modular and non-modular type, and in custom and standard configurations. All are supplied with removable central steelwork configured as per the customer's requirements - be it the typical handling crucifix/padeye arrangement or a through hawse for use with anchor wire rather than chain.

Suitacase Anchor Pendant Buoys

Evergreen Suitcase Anchor Pendant Buoys are designed to withstand the rigorous conditions associated with the offshore industry.

Evergreen Suitcase Anchor Pendant Buoys are manufactured from resilient, closed cell polyethene foam. The closed cell structure of the resilient PE foam core menas that the buoy will not absorb water, even if the skin is punctured therefore maintaining buoyancy and functionality.

Designed specifically with large flat surfaces for safe and secure storage onboard anchor handling vessels, Evergreen Anchor Pendant Buoys have an enviable reputation for quality and performance.

Evergreen Anchor Pendant Buoys are constructed by laminating resilient PE foam around a central steel member with a number of internal load distribution plates, together with large gussets welded in position. This resilient PE core ensures that the buoy is completely self fendering (i.e. soft buoy), The rectangular shape also allows easy and safe storage and transportation.

The whole core is encapsulated within a self colored polyurethane elastmer protective coating which is resistant to abrasion and to ultra violet degradation.

The table blow shows a range of standard sizes only, other sizes or specific buoyancy / dimensions required are evaluated on application. A variety of steelwork options, e.g. anchor cross, pad eye, swivels etc. are available.

Standard colors are orange or yellow but other colors are available on request. Further options are available too.
