Donut EVA Foam Fender Dia 1.7m Polyurethane Cylindrical Rotational Fender

The foam hardness, skin thickness, pile / fender diameter and also the height of the fender can be changed on requirments. Luhang would be pleased to receive your design input allowing us to engineer the correct type, size and overall layout of the Rotational Donut Fender.

The Rotational Donut Fender is a specific type of Foam Fenders. It is designed for simply slip over a stationary monopile. Due to its construction, the fender floats up and down with the tide water levels and rotates when ships berthing and slide along the fender. The Rotational Donut Fender is designed with material of closed cell eva foam, a reinforced protective polyurea coating outside and several low friction pads at the internal steel cylinder.

Donut Fender Applications

• Dock entrances, corner protectionS, turning dolphins, bridge protections or areas with large tidal variations.
• Other monopile structure
• Submarine jetty

Performance of normal size Rotational Donut Fender

Rotational donut fender is an effective fendering solution for the berthing dolphins, guiding rotational structures, and corner protection facilities. Donut fender is separated with the tubular pile. There is low friction bearings to the pad, which can ensure the donut fender float up and down and freely.
