Pneumatic Fender have been in use for around 50 years. It is the leading anti-collision device for marine application in the world. This compressed air filled rubber fender is used as a protective medium for ship-to-ship contact (STS), ship to quay (STQ) and ship-to-berthing (STB).



Pneumatic Fenders can be delivered in various sizes and types. Pneumatic Fenders  with Chain and tyre net (CTN) type is usually recommended to protect the pneumatic fender body, but the sling type or body only is also available.

Pneumatic Fender Performance

The guaranteed energy absorption of Pneumatic Fenders is the energy absorption at 60% deflection. This value can be use in engineering design and actual operation. Table gives the sizes, weights and technical performance of Pneumatic Fenders.

Note : 

1 Energy represents the Guarantee energy absorption at 60% deflection.
2 The weight is Pneumatic Fender’s body weight without protective net may vary ± 10%
3 Reaction Force, R ± 10%; Deflection: ± 5% and each of the reaction force and energy absorptionare measured under static condition.
4 Special Sizes of others dimension are available upon request. 

Four large-size Pneumatic Fenders are usually floated at the water line as primary fenders to absorb impact energy at berthing and keep proper stand-off distance between two ships. Two small-size Pneumatic Fenders (secondary fenders) are hung high on the hull at both bow and stern of smaller ship to prevent contact from rolling of ships due to swell and wind. "STS Transfer Guide", published by the International Chamber of Shipping (OCIMF), is a good reference for further information.
