2. Inflatable Rubber Fender Introduction
The "Yokohama Type Inflatable Rubber Fender" was developed in 1958.
Progress in the development of such floating inflatable rubber
fenders is closely related to the progress and development of ship
technology, and has to continuously cope with progressively larger
oil tankers such as VLCC's, ULCC's, large gas carriers, bulk
carriers and floating structures.
Floating Inflatable Fenders are used world wide for ship-to-ship
(STS) transfer operations, terminals, and for all kinds of ships.
Since its creation until today, more than millions of fenders have
been supplied worldwide both for ship-to-ship and ship-to-dock
(STD) operations serving our valuable customers. These fenders play
a critical role in the safe operation of ship berthing and mooring.

4. Henger Inflatable Rubber Fender Advantages
4.1. Safety and Reliability
Henger Inflatable 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.
4.2. No Deterioration or Variation in Performance
Henger Inflatable Rubber Fenders utilize the compressive elasticity
of air, therefore
performance deterioration due to fatigue is absent.
4.3. Advantages at Inclined Berthing
Henger Inflatable Rubber Fenders, energy absorption does not
decrease at inclined compression up to 15 degrees.
4.4. Most Cost Competitive System
The utilization of the compressive elasticity of air provides
completely uniform surface pressure on contact, making Henger
Inflatable Rubber Fenders ideal. The surface pressure of the Henger
Inflatable Rubber Fenders is equal to the internal air pressure.
Due to low and uniform surface pressure properties, the Henger
Inflatable Rubber Fenders are popular at LNG-ship terminals.
4.5. Soft Reaction Force for Ship and Jetty Structure
The reaction force of Henger Inflatable Rubber Fenders does not
increase sharply, even under excess load conditions. Therefore, the
Henger Inflatable Rubber Fenders perform well in such cases, and
protect ships and mooring facilities.
4.6. Lower Mooring Forces under Rough Weather Conditions
The reaction force and deflection of Henger Inflatable Rubber
Fenders do not easily reach the maximum because the reaction force
increases slowly and allowable deflection is wide. Thus, the Henger
Inflatable Rubber Fenders safely protect ships and mooring
facilities even under rough weather.
