2500mm x 5500mm Pneumatic Rubber Ship Fender
Product Introduction:
Rubber ship fender is also known as pneumatic rubber
fender,Yokohama type fender. It was fiest invented by the
manufacturer of YOKOHAMA, so it now also called Yokohama fenders.
After years of improvement, Shunhang's Yokohama fenders used
special technilogy and material, makes it to have better
performance .
Rubber ship fenders play a critical role in the safe operation of
ship berthing and mooring. and became the world's leading anti-collision device.It's widely used for ship-to-ship (STS) transfer operations, ship
to quay (STQ) operations and ship-to-berthing (STB) operations.
Raw Material
Inner layers is special air sealing layers.
The outer rubber layer is UV-proof and anti-abrasion.
The middle material is rubber layers reinforced with cord net.
All metal parts contacting with sea water such as flanges, bolts,
pins etc adopt HDG steel.
Safety Valve
Rubber ship fenders of diameter 2500mm and larger sizes shall be
equipped with a safety valve for releasing excess internal pressure
when the fenders are over-compressed accidentally. Fender which is
smaller than 2500mm in diameter can also be equipped with a safety
valve if requested.
Advantage of Rubber Ship Fender:
1. Compliance with ISO 17357: 2014
2. Easy to install and use.
3. Various optional fittings.
4. Cost competitive system
5. Low maintenance cost.
6. Adaptable to the tide.
7. Low reaction and hull pressure.
8. Maintains large clearances between hull and structure.
