Customized PU Coating Foam Fender Donut Fender For Jetty Protection
The Donut Fender is a specific type of Foam Fenders. It is designed to simply slip over a stationary monopile. Due to its construction, the fender floats up and down with the fluctuating water levels and rotates when vessels berth and slide along the fender. The Donut Fender is designed with a 100% closed cell cross-linked polyethylene foam core, a reinforced elastomeric skin and low friction pads at the internal steel core.
Donut Fenders are available in diameters from 1,270 mm to 4,220 mm and a maximum pile diameter of 610 mm to 2,388 mm. Additionally, mooring crowns, counterweights (for sub-marine applications) or other features like protective nettings can be added.
The foam hardness, skin thickness, pile/fender diameter and also the height of the fender can be changed on request. ShibataFenderTeam would be pleased to receive your design input allowing us to engineer the correct type, size and overall layout of the Donut Fender.
Dnout Fenders are an effective solution for simple berthing dolphins, guiding and turning structures. The buoyant Donut floats up and down a single tubular pile and freely rotates to help align or redirect ships. The internal casing has long-lasting, low-friction bearings which need minimal maintenance. The foam is unsinkable and cannot burst or deflate. The Donut skin is durable polyurethane reinforced with continuous nylon filaments.
LUHANG Donut Fenders are custom designed for every application. They can have supplementary buoyancy to present a raised contact face. The body can be additionally protected with rubbing strips to cope with ferry beltings. Bright colors are often used to improve visibility and safety.
