Floating Donut Marine Foam Fender for Monopiles

Floating Donut Marine Foam Fender for Monopiles is a specific type of Marine Foam Fenders. It is designed to simply slip over a stationary monopile. Due to its construction, the donut marine foam fender floats up and down with the fluctuating water levels and rotates when vessels berth and slide along the fender. The Donut Marine Foam Fender is designed with a 100% closed cell cross-linked polyethylene foam core, a reinforced elastomer skin and low friction pads at the internal steel core.

As a professional manufacturer of donut foam fenders, Qingdao Luhang engineers have developed the industry’s most customisable and versatile donut fendering solutions.

Luhang Floating Donut fenders are foam-filled energy absorbing fenders that have an open core in order to freely rotate about a stationary monopile or are mounted on a pier in such a way that they rotate as pressure is exerted by a vessel. Having a vessel roll off the fender nearly eliminates shear forces while making navigation much easier, especially to and from a berth in windy or high-current conditions.

Luhang Donut Monopile Floating Foam-Filled Fender is designed to simply slip over a stationary monopile and float at the fluctuating water line. Luhang’s internal anti-friction UHMW bearing pads allow the fender to slide around and up and down the pile allowing a vessel to roll along the moving fender enabling the fender to be at the same relative level to the vessel at all tides. When outfitted with an independent mooring crown, this fendering system provides and optimal all-tide mooring solution.

The basic design principle of the floating luhang Monopile Foam-Filled Fender is to provide an innovative fendering system that absorbs energy, adjusts to tidal fluctuations and eliminates shear forces. The ability of this fendering system to freely ride up and down and rotate around the driven stationary central steel pile even under compression achieves this design goal. The proven performance and versatility of the Luhang Monopile Fendering System make it ideal for even the toughest mooring applications.

Berthing design for the new fireboats

For the project, Luhang Donut Monopile Floating Foam Filled Fender was chosen to help protect the $50m+ fireboat investment. For the renovation of the fire boat berth, a solution was required that limited reconstruction of the docks, while adding all-tide moorings. Luhang Donut Monopile Floating Foam-Filled Fenders with independent mooring crowns were perfect for the task.

The 20ft Luhang Donut Fenders were designed specifically for these fire boats and set in the water to maximise the boats’ contact with the fender, thus reducing the pressure put on their hulls. In a race against time to get out to a fire or coming in from an emergency, the Donut Fenders allow the fire boats to leave or come back quickly, maximising contact energy absorption with their high density foam core and ability to roll off the hull, further absorbing the energy beyond a traditional stationary fender.

Sitting on top of the fenders are mooring crowns, which are robust steel structures that slip over the monopile and rest on top of the donut fenders. Each mooring crown is designed to rotate freely due to low-friction UHMW bearing pads and with multiple bollards for the vessel’s dock lines. Because the mooring crown rotates independently of the monopile and the donut fender, movement of the vessel in windy and high-current conditions puts less strain on the dock lines than if they were tied-down to a traditional fixed cleat on a dock or wharf.

Applications for luhang Donut Fendering Systems include breasting dolphins, turning dolphins, corner protection, as guiding structures, ferry vessel applications, dock fendering where large tidal changes occur, dock fendering where vessels need roll along fenders for loading, lock gate protection, and bridge/pier protection.
