One-piece Mooring Buoys
Subsea One-piece Mooring Buoys
In shallow or deepwater there will always be a requirement to safely moor a floating structure, it may be an oil tanker, production vessel, a semi-submersible drilling rig or deepwater platform. In most cases this mooring requirement will include chains, wire ropes and one or more subsea mooring or spring buoys.
Evergreen Subsea Mooring Buoys are available in a wide range of sizes and water depths, both in modular and non-modular form (one-piece buoy), and in custom and standard configurations.
One-piece mooring buoys are manufactured using a central tension member encapsulated within a syntactic foam core of varying densities to suit particular depth ratings. The external skin of one-piece mooring buoys include rotationally moulded polyethylene, polyurethane elastomer and glass reinforced vinyl-ester, giving a durable, abrasion resistant surface finish. The external surface is pigmented with a high visibility colour – typically yellow, white or orange – to assist with deployment and retrieval although other colours are available on request.
