Description

2.2m Dia 3M Height Low Reaction Floating and Rotation Foam Donut Fender on Mono Pile

Donut fenders are designed to float up and down with the tide on a circular mono-pile either driven into the bed or mounted on the face of a quay wall. Donut fenders are suited for lock entrances, turning structures, approach channels and breasting dolphins. Not only do Donut fenders rise and fall with the tide but due to the low friction guides located inside the fender they also rotate around the pile assisting in lining up vessels for mooring or guiding though a channel.

Generally Donut fenders are designed on a project by project basis taking into consideration the required berthing energy requirement and the size of the pile the fender will be installed on. The installation pile can either be existing or if new then the final size of the fender can be determined taking into consideration movement and therefore energy absorption of the pile.

How to Select and Order Suitable Foam Donut Fenders?

Generally Donut fenders are made to measure.
We have therefore given the dimensions, weight and performance (table on previous page) in groups of sizes designed to be an indication of performance only.
Precise design and finalised dimensions can be calculated with project specific pile dimensions and berthing energy/reactive load requirements.
