The Benefits of Using Pneumatic Fenders

1. Safety and Reliability

Yokohama Type Pneumatic Rubber Fenders are constructed of several layers of strong tire-cord, and are thus resistant to pressure and cutting. The safety factor adopted in the design of this fender is based on accepted theory and has been proven by extensive experimentation. large-size fenders are equipped with a safety valve to release the inside air in the event of accidental over-pressure.

2.No Deterioration or Variation in Performance

Jerryborg Marine Pneumatic Rubber Fenders utilize the compressive elasticity of air, therefore performance deterioration due to fatigue is absent. our Pneumatic Rubber Fenders also fully comply with the durability test required by ISO-1: . Any reduction of the guaranteed energy absorption (GEA) is not accepted.

3. Advantages at Inclined Berthing

5. Soft Reaction Force for Ship and Jetty Structure

The reaction force of Pneumatic Rubber Fenders does not increase sharply, even under excess load conditions. Therefore, the Pneumatic Rubber Fenders perform well in such cases, and protect ships and mooring facilities. In contrast, the reaction force of solid rubber fenders, including buckling-type fenders, increases sharply under excess load conditions.

it can be seen that the Pneumatic Rubber Fenders are ideal as fender system because of gentle treatment of ships in below table.

Pneumatic fenders are a type of equipment used for the safety of ships and docks, usually made of rubber or polyurethane materials. They are inflated to form a soft but strong buffer device, which can effectively absorb and disperse the impact force generated when the ship is berthing, protecting the hull and dock structure.

The following are some of the main features and advantages of pnematic/ inflatable fenders:

1. High energy absorption: Inflatable fenders can absorb a lot of energy, thereby reducing the impact force between the ship and the dock, effectively protecting the hull and dock.
2. Strong adaptability: This type of fender can be used in various environmental conditions, including ports, docks, docks and offshore facilities. They can withstand different weather and sea conditions.
3. Portability: Inflatable fenders are lightweight and easy to transport and install. Even in an emergency, they can be deployed quickly.
4. Easy installation: Compared with traditional solid rubber fenders, inflatable fenders are relatively simple to install and do not require complex fixings.
5. Low maintenance cost: Due to the durability of the material and the simplicity of design, the maintenance cost of inflatable fenders is low. Even if damage occurs, it can usually be repaired with simple repair measures.
6. Long service life: High-quality inflatable fenders are made of durable materials and have a long service life, and can maintain good performance even in harsh marine environments.

Inflatable fenders are widely used in commercial ports, military docks, fishing docks, and berthing operations of large ships. When choosing specific models and specifications, it is necessary to determine according to the type, size and berthing environment of the ship to ensure the best protection effect.
