Surface & Subsea Support Buoys
Evergreen-Maritime is the Leading Manufacturer of 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.
Introduction
Brief Introduction
A. Closed cell resilient foam core, unsinkable design
General surface support buoys are made with highest quality closed-cell PE/EVA foam. This resilient foam makes the buoys self fendering with high absorption capacity. Even the skin was punctured, it is also unsinkable without absorbing water. With our unique laminating process, each foam core is integrited. The foam core will not 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 the unique elastomer specifically used for offshore applications. Its high resistance to abrasion, fatigue and ultra violet degradation are 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 pad eye, clevis eye, swivel, chain locking plate, single locking pin end fitting are available.
