Donut Fender
Donut fenders are a special type of foam fender. It is designed to simply slip through fixed single piles as an effective solution for simple dolphin mooring, guiding and steering structures.
The donut fender is very similar in structure to a foam-filled floating fender, with a 100% closed-hole cross-linked polyethylene foam core, a low friction pad design that enhances the elastic skin and the inner steel core. The foam does not sink and does not burst or degass.
The donut skin is a durable polyurethane reinforced with continuous nylon filaments, giving them all the ideal properties for optimal maintenance-free use.
As with foam fenders, any size change is possible, allowing the fenders to fit their purpose, they can be made into a variety of colors. Donut fenders range in diameter from 1,270 mm to 4,220 mm and maximum pile diameters from 610 mm to 2,388 mm.
In addition, mooring crowns, counterweights (for submarine applications) or other functions, such as protective nets, can be added. Typically, the donut fender is designed with residual buoyancy to render the mooring surface over the waterline, but some devices use separate buoyancy chambers and underwater bodies to reduce impact, and this versatile fender can achieve all changes.
