Floating pneumatic rubber fender
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.

1 Safety and Reliability
Yokohama 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.
2 No Deterioration or Variation in Performance
Yokohama Pneumatic Rubber Fenders utilize the compressive
elasticity of air, therefore
performance deterioration due to fatigue is absent.
In the case of solid rubber fenders or foam-filled fenders, based
on data were taken
from comparison tests of Yokohama Fenders, there are variations in
performance. Such
performance variations are associated to changes of rubber or foam
hardness occurring
as a result of cyclic compression and temperature change.
The good performance of the Yokohama Pneumatic Rubber Fenders
remains unchanged
even at temperatures under -50 degrees Centigrade (-58 degrees
Fahrenheit).
3 Advantages at Inclined Berthing
Ships usually make initial contact with the dock or another ship on
STS operations at an
oblique angle.
In the case of Yokohama Pneumatic Rubber Fenders, energy absorption
does not
decrease at inclined compression up to 15 degrees.
4 Most Cost Competitive System
The utilization of the compressive elasticity of air, unlike other
fenders which need protector panels, provides completely uniform
surface pressure on contact. The surface pressure is equal to the
internal air pressure
5 Stronger against Shearing Force
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.
6 Simple and Low Cost Installation
The weight of Yokohama Pneumatic Rubber Fenders is supported by the
water on which it floats.
Therefore, the fender can be moored simply by means of a guy rope
or chain, requiring minimal extra
cost. It can be removed easily to a suitable jetty or quay when not
in use, or transferred to another
mooring point whenever required.
7 Low Maintenance Cost
Maintenance cost is very low. Although the internal pressure will
vary with seasonal changes, the air leakage is so minimal that it
is sufficient to check the air pressure only once a year. The chain
net needs to be replaced only once in 3 or 4 years, depending on
ambient conditions.
8 Shipping Cost Minimization
In order to minimize the shipping cost of Yokohama Pneumatic Rubber
Fenders, the fenders are usually packed and shipped in containers
or on pallets in vacuumed and folded down state.
1. Pneumatic Rubber Fender Transportation
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. Pneumatic Rubber Fender Types
Type I: pneumatic rubber fender with Chain & tyre net protective
jacket
Type II: Sling type with rubber plate, rubber tube & ropes
protective jacket
Type III: Ribbed type rubber fender

2. Specially Designed and Strengthened Casting Flange
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.
3. Pneumatic Rubber Fender storage
1. When the Pneumatic rubber fender is not used for a long time, it
should be washed and dried, filled with appropriate compressed air,
placed in a dry, cool, ventilated place.Inventory temperature is
maintained at -15 ℃ -40 ℃ .
2 .The place where the fender is stored should be kept away from
the heat source.
3 .Fenders shall not be in contact with acids, alkalis, greases and
organic solvents.
4 .When the fenders are not in use, they must not be stacked and
should not be stacked on the ba. In order to better extend the
service life of pneumatic rubber fenders, it is recommended that
you store them in strict accordance with the above recommendations.
4. Pneumatic Rubber Fender Inflation process
1. Install the inflatable rod
2. Remove the valve core with the wrench
3. Link up quick connector inflation, inflation pressure
0.05-0.08mpa, recommended pressure 0.05mpa.
4. pressure by gauge
5. Screw the valve core with the wrench
