Pneumatic Rubber Defense Yokohama Marine Floating Fender
1.Introduction
The fender is mainly to withstand the impact force of the ship when
the ship is docking, leaving the dock and other forms (such as when
the ship is tied to tow), and transmits it to the hull structure of
a larger area. Wooden fenders have buffering effect. Although steel
fenders have poor buffering effect, they have better strength and
can be included in the section of the hull girder (the welding
strength must be guaranteed). Especially for large-open deck
barges, they can make up for the deck The lack of effective
cross-sectional area is conducive to longitudinal strength. Steel
materials cannot be used for the fenders of oil barges and small
oil tankers.
Large seagoing vessels usually do not have fenders. River boats,
work boats, permanent double-track fenders, one of which is located
on the upper deck, and the other is located slightly higher than
the designed waterline.
2 . Features
Comparison of Henger Pneumatic Rubber Fender and traditional
elastic rubber fender:
1. High impact energy absorption, low impact force on the ship
2. Simple installation
3. Good elasticity, no deformation under the action of compression
4. Lightweight, practical and economical
3. 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.
4. Application
Pneumatic Rubber Fenders are suitable for many applications
including:
1. Tankers, Gas Carries and Bulk Cargo Ships;
2. Fast ferries and aluminum hulled vessels;
3. Temporary of permanent installations;
4. Rapid response and emergency fendering;
5. As stand-off fenders to realign ships with shore facilities.

6. Advantage
1. Safety and Reliability
Boat Rubber Fender 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.
2. No Deterioration or Variation in Performance
Boat Rubber Fender utilize the compressive elasticity of air,
therefore performance deterioration due to fatigue is absent.
3. Advantages at Inclined Berthing
Boat Rubber Fender, 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 provides
completely uniform surface pressure on contact, making Boat Rubber
Fender ideal. The surface pressure of the Boat Rubber Fender is
equal to the internal air pressure. Due to low and uniform surface
pressure properties, the Henger Pneumatic Rubber Fenders are
popular at LNG-ship terminals.
5. Soft Reaction Force for Ship and Jetty Structure
The reaction force of Henger Pneumatic Rubber Fenders does not
increase sharply, even under excess load conditions. Therefore, the
Boat Rubber Fender perform well in such cases, and protect ships
and mooring facilities.
6. Lower Mooring Forces under Rough Weather Conditions
The reaction force and deflection of Boat Rubber Fender do not
easily reach the maximum because the reaction force increases
slowly and allowable deflection is wide. Thus, the Henger Pneumatic
Rubber Fenders safely protect ships and mooring facilities even
under rough weather.
6. 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.
7.Company Introduction
In general, for ship-to-ship operation of light ships, two points
of contact are sufficient. However, for the operation of large
ships by ship, an additional 1-2 fenders of the same specification
must be used to ensure safety. Inflatable rubber fenders can be
used as the main protection system to absorb the energy of the ship
to the ship, while keeping the two ships at a certain distance. In
addition, a small inflatable rubber fender can also be hung on the
side of the ship as a secondary protection. Inflatable rubber
fenders require chains and rope links to be hung from the ship or
dock, and their specifications are selected according to the size
of the fender and the environment in which it is used.
