1.52m Dia Foam Filled Marine Donut Floating Fender for Turning Dolphins
As a professional manufacturer of foam filled donut fenders, Qingdao Luhang is supplying with this versatile donut fenders for many ports and docks around the world. Generally Foam Filled Donut fenders are designed with residual buoyancy to present the berthing face above the water line but some installations have utalised separate buoyancy chambers and submerged bodies for low impacts, all variations are possible with this versatile fender.
It is also possible to install any combination of mooring points or secondary fenders to the donut fender. These can be designed bespoke for your application.

6. Individual drafts can be controlled by counterweights
Sizes and Performance of Foam Donut Fenders
The performance of the standard size Donut fenders given below represents a small selection of sizes selected to give an indication of the performance of a fender as a guide only.
|Pile Diameter (PD)||
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 install the donut fenders?
Installation of our Donut Fenders is very easy. The fenders will be delivered to site ready for installation on the fender piles. Once lifted over and lowered onto the fender pile the fender should be ready for use. Ballasting or trimming is not required as the fender will float at the designed level. Finally a capping feature can be placed over the top of the fender pile to finish the installation off. Maintenance of our donut fenders is very low as the internal bearings are designed to allow the fender to rotate and float up and down with the tide for a period of 25 years.
Any additional equipment installed with the donut fender such as secondary fenders or mooring points should be maintained separately.
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.
