SGS 50Kpa Yokohama Floating Fender for Corvette Ship & Frigate High Energy Float Fender

Yokohama Floating Fender

Yokohama floating 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 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 floating 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 fender supplies with a variety of specifications and dimensions to meet customer’s requests and different application conditions. 

Yokohama Floating Fender Structure

① Outer rubber layer

Float 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.

Yokohama Floating Fender Advantage

1. Safe and Reliable

Float fender is made of several strong cord layers to enable it to be pressure-resistant and puncture-resistant. The float fender whose diameter is over 2.5m is equipped with a safety valve to release the air inside in case it’s overpressured. The diagram below shows the data variations at different percentage compressions.

2. No Variation or Deformation in Performance

Float fender is filled with the air of compressive elasticity inside, the deformation caused by fatigue is absent. In the experiment below of high-pressure floating pneumatic fender, the performance variation will not happen if the pressure is maintained properly.

Our fender remains the same without any variation or deformation even at temperatures under -50 degrees centigrade (-58 degrees Fahrenheit).

3. Advantage under Severe Weather Conditions

Under normal circumstances, the ship movement caused by high and long-period waves or strong wind will bring repeated compression and shearing forces on the fender and make it easier to be fatigue and damage. However float fender is strong enough to resist severe weather conditions, the reaction force increases slowly compared with solid fender and won’t easily reach the maximum.

4.Shape Conformant at Inclined Compression

Float fender is made of reinforced cord layers of high elasticity and flexibility, which enable it to make it shape conformant at inclined compression during ship-to-ship operations. Compared with solid fender and foam fender, the fender is easier to distribute the load along the ship's body or berthing structure.

5. Relatively Low Economic Cost

With the advantage of compressive elasticity of air, the surface pressure of float fenders is completely uniform, which is equal to the internal air pressure and makes it popular with LNG-ship terminals.

6. Tide Adaptation

Float fender is filled with pressure air inside that makes it flexible and easy to float on the water and adapt to the tide variation.
