Customer Reviews
I’m late in sending this, but wanted to thank Jerryborg Marine for the great job they did on the pneumatic fenders that they fabricated for me. They work perfectly and serve a long time. Very glad I found them.

—— Deepark-Dolphine Rubber

The guys over at Jerryborg Marine not only provided quick estimates, an honest timetable, and professional courtesy, but also quality work that exceeds their fair pricing. I recommend them for anyone's next project.

—— Thanh Dong-Vietnam Ecomarine

I choose Jerryborg Marine because I simply could not find any other provider that offered all the marine products I needed under one platform, such as pneumatic fenders, anchors, chains, steel wire ropes, shackles.

—— Alessandro Bitocchi-PSG AB

I have a problem with products from another vendor. The engineer of Jerryborg Marine is very enthusiastic and helps me a lot to solve the problem. I really appreciate their professional work and experts team.

Hydropneumatic Fender

Hydropneumatic fender was developed in Japan in 1958. It should be manufactured according to ISO 17357. The standard defines the corresponding international standards for the materials and testing of these fenders. In most cases, the Hydropneumatic fender should be surrounded by tires and chains to provide additional protection. The fender can also be reinforced with rubber ribs(rib fender) without tires and chain mesh (sling fender).



Hydropneumatic Fender Advantage


1. Light weight, high compression deformation, low reaction strength, and high energy absorption.

2. Good floating performance, can meet the needs of water level changes.

3. Using compressed air as the medium, the energy consumption of the collision may not be compressed air.

4. Easy to install and long service life



Hydropneumatic Fender Classification


Marine rubber buffers are produced with two initial pressure ratings, which are pneumatic 50 (P50, initial internal pressure 50kPa) and pneumatic 80 (P80, initial internal pressure 80kPa).


Marine rubber buffers are mainly classified into three types as follows:

1. High-Pressure Marine Rubber Buffer with Chain and Tyre Net

With chain and tire net covering the buffer body, the marine rubber buffer 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 Marine Rubber Buffer

Sling type marine rubber buffer will be connected with a guy chain or guy rope with a lifting device on both ends.


3. Hydro Pneumatic Type Marine Rubber Buffer

Hydropneumatic marine rubber buffer 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 buffers mentioned above are available usually in black, the color is also customized upon your request. Jerryborg offers fenders with various sizes in diameter ranging from 500mm to 4500mm, length ranging from 1000mm to 9000mm.


4. Other Types

Hydropneumatic Fender Structure


① Outer rubber layer

Marine rubber buffers 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.
