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.

Yokohama Type Pneumatic Fender


Yokohama type pneumatic fender, also called Yokohama fender, has been used in port, harbor, and maritime operations for decades since it was developed in 1958. Fully compliant with the ISO17357 standard, Jerryborg’s Yokohama type pneumatic fender supplies with a variety of specifications and dimensions to meet customer’s requests and different application conditions.


Yokohama type 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.


With the development of ship technology, this Yokohama type 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.



Yokohama Type Pneumatic Fender Structure


① Outer rubber layer

The outer rubber layer uses special compounds that provide additional tensile strength and tear strength to protect the fender from severe weather conditions and frequent use.


② Synthetic-tire-cord layer

The reinforced layer is a composite tire cord with cross shadow lines, which is designed to distribute stress evenly.


③ Inner rubber layer

The inner rubber layer is specially designed to seal the internal air and prevent any leakage, just like the inner tube of a tire.

Yokohama Type Pneumatic Fender Classification


Yokohama type pneumatic fenders are produced with two initial pressure ratings, which are pneumatic 50 (P50, initial internal pressure 50kPa) and pneumatic 80 (P80, initial internal pressure 80kPa).


Yokohama type pneumatic fenders are mainly classified into three types as follows:

1. Yokohama Type Pneumatic Fender with Chain and Tyre Net

With chain and tire net covering the fender body, the Yokohama type pneumatic 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. Besides, as for the protective tire, Jerryborg offers four types of tires with different sizes and thicknesses for customers to choose from.


2. Sling Type Yokohama Type Pneumatic Fender
