Floating Polyurethane Monopile Donut Fenders For Ship To Jetty

Floating Polyurethane Monopile Donut Fenders For Ship To Jetty

Monopile Donut Fenders are versatile, robust and suitable for almost all applications. The manufacturing process allows for virtually any size of fender to be constructed and selecting the appropriate grade of foam core and elastomeric skin means the performance of a fender can be precisely gauged to meet specific specification requirements.

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.
