Qingdao Henger Ship Supplies Co., Ltd.
1. Pneumatic rubber fender introduction
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 pneumatic fenders are used world wide for ship-to-ship
(STS) transfer operations, terminals, and for all kinds of ships.
Since its creation until today, Henger more than 10,000 fenders
have been supplied worldwide both for ship-to-ship and ship-to-dock
operations serving our valuable customers.These fenders play a
critical role in the safe operation of ship berthing and mooring.
What type do we have?
Tire net type: multiple tires are tied to the ball, and both ends are tied to a
special flywheel that can rotate flexibly. Suitable for large and
reliable balls.
Rubber net type: tie a special rubber pad to the ball, which can be freely
contracted or stretched when squeezed. Suitable for medium and
small reliable balls.
Line type: The net cover is woven with nylon rope; tightly tied to the ball.
It is suitable for small size reliable balls.
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.

4. Advantages of inflatable rubber fenders
Unique Design of Henger Pneumatic Rubber Fender
Active-Protecting Safety Valve , All fenders are equipped with a
safety valve to release the inside air in the event of accidental
over-pressure.
It is a patented design which could avoid explosion of fenders from
collision and air inflation.
Henger Flange is casting of corrosion-resistant iron with
galvanized anti-corrosive coating, which will strongly prolong the
fender quality and service life. The strength of Henger casting
flange improves 40% higher than traditional type.
"Henger" management system has passed ISO9001:2008 certification,
"Henger" guarantees the high standards and excellent performance of
all products. "Henger" attaches great importance to the quality
control of rubber fenders, and each fender is tested according to
ISO17357:2002 requirements.
"Yokohama Pneumatic Inflatable Rubber Fender " progress in the
development of such floating pneumatic 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 pneumatic fenders are used world wide for
ship-to-ship (STS) transfer operations, terminals, and for all
kinds of ships.
After contacting a dock, a ship is usually shifted to the correct
mooring position. The
shifting exerts shearing and compression forces on the fenders.
This combined force is
very severe in the case of solid rubber fenders because they are
not reinforced against
such force. In contrast, Yokohama Pneumatic Rubber Fenders are
adequately
reinforced using strong tire-cord to cope against such forces as
well as internal
pressure.
5. Transportation and application of inflatable rubber fender
Transportation We can take the deflation pallet transportation and
the entire fender transportation without deflation according to the
requirements of customers. We always put the customer's
requirements first.
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
Pneumatic Rubber Fender is constructed of synthetic-cord-reinforced
rubber sheets with compressed air inside to keep floating over the
water surface and work as a shock absorber between two ships or
between ships and berthing structure when they come alongside each
other on the water.
Pneumatic Rubber Fender is a leading anti-collision device for
marine application in the world today. Pneumatic Fender has become
an idea ship protection medium used extensively by large tankers,
LPG vessels, ocean platforms, large docks, harbors and wharves.
