Air-tightness Floating Pneumatic Fender Natural Rubber Ship Bumpers With CCS Authorized

 

 

Air-tightness Floating Pneumatic Fender

 

Air-tightness floating pneumatic fender, also called Yokohama fender, has been used in port, harbor, and maritime operations for decades since it was developed in 1958. With the development of ship technology, this air-tightness floating pneumatic fender is used extensively in ship-to-ship transfer operations and ship mooring and berthing operations. It’s always regarded as a buffer to reduce shock in between due to its excellent performance of great elasticity and abrasion-resistance.

 

Air-tightness floating pneumatic fenders are divided into three types, including sling type, hydro-pneumatic type, and chain and tire net type. Each type plays a critical role in protecting the safety of marine operations.

 

Fully compliant with the ISO17357 standard, Jerryborg’s air-tightness floating pneumatic fender supplies with a variety of specifications and dimensions to meet customer’s requests and different application conditions. 

 

 

Air-tightness Floating Pneumatic Fender Advantage

 

1. Absorb more energy and reduce the adverse impact on the ship


2. Adapt to the tide.


3. Safely overload.


4. Lightweight and easy to install.


5. Easy to maintain.


6. Long service life.


7. Different sizes can be customized upon customer’s requirements.

 

Pneumatic ship fenders are mainly classified into three types as follows:

 

1. Pneumatic Ship Fender with Chain and Tyre Net

With chain and tire net covering the fender body, the pneumatic ship fender can reduce the damage of friction and abrasion caused by direct contact. Therefore it’s widely used in places with complicated and unstable tide variation, such as ship-to-ship(STS) and ship-to-dock(STD) operations. In addition, as for the protective tire, Jerryborg offers four types of tires with different sizes and thicknesses for customers to choose from.

 

2. Sling Type Pneumatic Ship Fender

Sling type pneumatic ship fender will be connected with a guy chain or guy rope with a lifting device on both ends.

 

3. Hydro Pneumatic Type Ship Fender

Hydropneumatic ship fender is usually used as a bumper with submarines and other semi-submersible platforms. It can be installed vertically in the water cause it’s filled with air and water inside and equipped with a counterweight.

All these pneumatic ship fenders mentioned above are available usually in black, the color is also customized upon your request. Jerryborg offers pneumatic ship fenders with various sizes in diameter ranging from 500mm to 4500mm, length ranging from 1000mm to 9000mm.

 

 

Air-tightness Floating Pneumatic Fender Structure

 

① Outer rubber layer

Air-tightness floating pneumatic fenders are covered by the outer layer made of natural rubber. This rubber compound is strong enough to protect the inner layer and synthetic-cord layer from the damage of external forces and severe weather conditions due to its high elasticity and abrasion resistance.

 

② Synthetic-tire-cord layer

The Synthetic-tire-cord layer is made of synthetic-tire-cord fabrics, compared with synthetic canvas fabric and synthetic belt fabric, this reinforcement layer performs better in fatigue-resistance and pressure-holding.

 

③ Inner rubber layer

The inner layer is designed to seal the air inside the fender.
