Manufacturer for Tug Fender - Polyurea Skin EVA Foam Filled Donut Fender – Haohang Detail:

Product Description

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.



Proportional load deflection curve
Low shear forces
Self-adjusting to changing water levels
Low installation costs
Generally maintenance free
Individual drafts can be controlled by counterweights

High energy absorption prevents damage to both the fender and moored vessels and makes berthing operations easier and safer.
Quick and easy installation
Manufactured from durable and reliable materials to minimise maintenance costs and maximise performance and lifetime of the fender


Energy Absorption

The below curve shows the Energy Absorption of the considered HAOHANG Donut Fender under a different % of Compression. Only one side of the Fender is working during compression and not its entire diameter. Performances are usually given up to a compression of 60 % however higher compression is occasionally permissible during short periods of time when accidents occur.

A deflection at and higher than 75 % if applied over hours will reduce the ability of the foam to recover its original shape. It will however continue to insure its securing function. Please note that for such high compressions there is a risk of damaging the internal steel parts of the Donut Fender. 


Reaction Force

The “Reaction Force” Curve shows the forces generated both on the Vessel hulls and the Steel Monopile during compression of the Donut Fender.
