Dock Ship Protection ISO17357 Floating Yokohama Fender
How does the fender work?
The pneumatic fender or inflatable rubber fender or Yokohama fender compressed air is used as a buffer medium to absorb the impact energy of the ship, so that the ship has more flexibility and flexibility when docking, so as to prevent The impact of collisions and collisions.
1. Oil and gas tankers
2. Fast ferries and aluminum vessels
3. Temporary and permanent installations
4. Rapid response and emergencies
5. In ports with extreme tidal variations
6. For ship-to-ship lightering operations
7. For all navy vessels due to low hull pressure and the advantage of a proportional increase of reaction force and energy absorption

1. Safe and reliable
Marine rubber fenders are constructed from several layers of strong tire cord and are therefore resistant to compression and cuts. The safety factor used in the design of this fender is based on accepted theory and has been proven through extensive experiments. Large fenders are fitted with safety valves to release internal air in the event of accidental overpressure.
2. No deterioration or change in performance
Marine rubber fenders utilize the compressive elasticity of air, so there is no performance degradation due to fatigue.
3. Advantages of inclined mooring
Marine rubber fenders with no reduction in energy absorption when tilted compressed up to 15 degrees.
4. The most cost-competitive system
Utilizing the compressive elasticity of air to provide a completely uniform surface pressure upon contact, making rubber boat fenders an ideal choice. The surface pressure of marine rubber fenders is equal to the internal air pressure. Henger pneumatic rubber fenders are popular in LNG ship terminals due to their low and uniform surface pressure.
5. Soft Reactions of Ship and Wharf Structures
Even under overload conditions, the reaction force of Henger pneumatic rubber fenders does not increase drastically. Therefore, marine rubber fenders perform well in this situation and can protect ships and moorings.
6. Reduced mooring force in bad weather conditions
The reaction force and deflection of marine rubber fenders are not easy to reach the maximum value, because the reaction force increases slowly and the deflection is allowed to be large. Therefore, even in bad weather, Henger pneumatic rubber fenders can safely protect ships and moorings.
Advantage
Unique design of HENGER pneumatic rubber fenders
Active protection safety valve, all fenders are equipped with safety valve to release internal air in the event of accidental overpressure.
