Pneumatic Rubber Fenders
Pneumatic Rubber Fenders are mainly used in ship-to-ship (STS) and ship to dock/jetties (STD/J) projects. The Pneumatic Rubber Fender is also known as the Yokohama type Fender/Floating Fender/Dock Fender. These kinds of Yokohama Fenders became the world's leading anti-collision device.
Pneumatic Rubber Fenders are fast and easy to install, keeping suitable clearances between the hull and the jetty or vessels. These ship fenders played a critical role on the safe operation of ship berthing.
SUPERIOR GUARANTEE SUPREME GUARD
NANHAI Pneumatic Rubber Fenders has the lowest single-application cost in the industry
Floating Pneumatic Rubber Fenders application cost depends on service life and usage frequency. High-performance NANHAI Pneumatic Rubber Fenders can minimize the single-application cost of users.
Safety and Reliability
The safety factor adopted in the design of this fender is based on accepted theory and has been proven by extensive experimentation.Operational experience over a long period of time attests to its high safety and reliability,and hydraulic pressure tests have proven the strength to be suitable.
Application in harshest conditions
Supply of high quality and reliable fenders that can perform effectively even under the harshest environmental conditions. It is therefore extremely crucial for each Pneumatic Rubber Fender to comply with the ISO 17357-1:2014.Application environment is bad,strong wind and waves.Fender compression over 70% still keep superior performance to fully protect ship,not burst. #LargeVessel #StrongWaves #StrongWind
Pneumatic Rubber Fenders durability
Reliant on the compressive elasticity of air, Nanhai floating Pneumatic Rubber Fenders show no deterioration or variation in performance due to fatigue or extremely low temperatures (-50°C and below) thereby negating the need for owners to make regular replacements.
Installation is simple and inexpensive, fender is supported by its own weight in the water. As such, it can be moored easily by means of a guy rope or chain, it can be removed with ease for transfer to another mooring point.
Larger-sized Pneumatic Rubber Fenders
Floating Pneumatic Rubber Fenders' diameter is 300 mm minimum and the maximum will be 4,500 mm. The range of lengths are 500 mm to 12,000 mm, as well as special sizes. The sling-type or chain & tire net(CTN) are available for both sizes.
Customized floating Pneumatic Rubber Fenders
- NANHAI could supply normal size floating Pneumatic Rubber Fender,meanwhile we could manufacture any size to meet user's requirements.The picture shows product is D3.3*L12.7m special size fender.
- The colors are usually be black and grey (Navy), if you need more we would like offer customized service.
