Donut 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.
Trelleborg's 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.
