BV For Pneumatic Rubber Fender With Tyre To Ship Protection 50KPa
Or 80Kpa
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.

♦ Definition:
The pneumatic rubber fender uses compressed air as the buffer
medium, which makes the ship have better anti-collision effect when
it is near the ship or dock.
♦ Characteristic:
● External wear resistance
● Bearing pressure
● Ageing resistance
● Long service life
● Good air tightness
● Easy storage
● Non deformation
● Simple installation
♦ Functions & Applications
● Installed on the wharf and dock for berthing
● Installed on the shipboard for berthing
● Float chamber
● For moving the cargo
● Pipe seal

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
4. Pneumatic rubber fender introduction
Pneumatic rubber fender is one kind of ship berthing, cushioning
and protection equipment, which uses compressed air as the buffer
medium to prevent collision when the ship is berthing. The
pneumatic rubber fender is more economical and durable than the
ordinary rubber fender, so it is more popular and widely used.
Pneumatic Rubber Fender is a leading anti-collision device for
marine application in the world today and has become an idea ship
protection medium used extensively by large tankers, LPG vessels,
ocean platforms, large docks, harbors and wharves.
5. Pneumatic rubber fender introduction
1 Outer rubber
The outer rubber layers that covers the outside of fender protects
the cord layers and the inner rubber from abrasion and other
external forces. This compound has sufficient tensile and tear
strength to withstand any weather condition and hard usage.
Standard color is black, but other colors are available on request.
2 Inner rubber
The liner of a rubber membrane seals the pressurized air inside the
fenders.
3 Synthetic tire cord layers for reinforcement
The reinforcement layers, which are made of synthetic tire cord
commonly used in tires, are arranged at ideal angles to hold the
internal pressure and to distribute the stress evenly providing
strong efficient reinforcement.
4 Beading ring
A steel ring is placed at one end (or both ends) of the fender and
holds the end of cord layers.
5 Flange
A steel flange is mounted on the fender, to which an air valve or
safety valve can be adapted.
6 Safety valve
Fenders of diameter 2500mm and larger shall be equipped with safety
valve for releasing excess internal pressure when the fenders are
over-compressed accidentally. Fender which are smaller than 2500mm
in diameter, can be equipped with a safety valve if required.
7 Metal accessories
All the relevant metal accessories of pneumatic fenders, include
shackles, towing rings, swivels, chain net, are made of stainless
steel, which are resistant for sea water corrosion.
