Sling Pneumatic Fender Edge Port Marine Fender Inflatable For Ship
Protection
Floating pneumatic fenders are used worldwide in Ship-to-Ship (STS)
transfer operations, docks and various vessels. Used in
ship-to-ship and ship-to-dock operations, fenders play a vital role
in the safe operation of ship berthing and mooring.
1. ISO 17357-1:2014 certified
2. Guaranteed energy absorption
3. Low hull pressures
4 Chain tyre net and Sling type
5. Thick skin construction
6. Good angular performance
Henger 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. Operational experience over a long period of time
attests to its high safety and reliability, and hydraulic pressure
tests have proven the strength to be suitable. Furthermore,
large-size fenders are equipped with a safety valve to release the
inside air in the event of accidental over-pressure. The figure
below shows data obtained from many destructive pressure tests at
various percentage compressions. Such data are used to establish a
basic minimum endurable pressure (MEP) curve for pneumatic rubber
fenders.
Ships usually make initial contact with the dock or another ship on
STS operations at an oblique angle. In the case of solid rubber
fenders or foam fenders, rated reaction force and energy absorption
decreases considerably at inclined compressions compared with
parallel compression. In order to compensate for the decrease of
energy absorption at inclined compression, it is necessary to use
larger sizes in the case of solid rubber fenders or foam fenders.
Distribution of load is also comparatively even because of the
molecular freedom of air and high flexibility of the multi-layered
cord-reinforced rubber membrane. This makes the body of a pneumatic
rubber fender more shape conformant compared to solid or foam
fenders, and thus able to better distribute the load along the hull
of a ship or jetty structure during inclined compression.
Henger Pneumatic Rubber Fenders basically float on the water in an
unrestricted vertical plane corresponding to the tidal range and
ship's vertical movement.
This means that energy absorption always takes place at the most
suitable position, and that only one fender is required per
dolphin.
