Spherical Buoys

The spherical buoy is one kind of representative pick-up buoy. It has a spherical shape or oval shape.

The steelwork construction through the buoy’s middle vertically. The spherical buoys can be supplied with swivel end or other end fittings designs. The spherical mooring buoys are constructed by resilient closed cell polyethylene / EVA foam around the inner central steelwork, covered by polyurethane (PU) outer skin. The resilient closed cell polyethylene/EVA foam core guarantees self-fendering and is unsinkable even in case of damage. And self-colored polyurethane elastomer skin is resistant to abrasion and ultraviolet ray degradation.

For extreme service environments, the polyurethane elastomer skin can be reinforced by nylon to protective coating that has higher tear strength, making the buoy long-lasting and virtually maintenance-free.

The spherical mooring buoys can be made of Synthetic Foam for deep water.
