Instruction of BV Approved Yokohama Type Ship Rubber Bumper
Pneumatic Fender
Pneumatic rubber fender is installed on the dock or ship, to absorb
the collision energy between the ship and the dock or ship when
berthing or mooring, and to protect the ship and the dock from
damage.
Pneumatic rubber fender has the advantages of low reaction force,
small surface pressure and reasonable energy absorption. In
berthing, the ship rolling and pitching adaptability, it will not
affected by the size of the ship and is widely used for
installation and maintenance convenient, especially suitable for
the dock.
Features of pneumatic rubber fenders
* Absorb more energy, less reverse impact on the ships
* More flexible ,easy installation
* Long term service life
* Not being bent out of shape under pressure
* Good air tightness, safety and reliability
* High shock absorption,low counter force and enhance port ability
* Produce according to ISO17357:2002 completely
* Many different sizes and shapes available
* Approve CCS, BV, RS, etc inspection
* Durable, practical and economical
* Good quality have been checked by many buyers
* Optional tire and chain ,can provide chain with hot galvanizing
or stainless steel
* Optional end fittings for the better suitable of applications.
Application of pneumatic rubber fenders

Purpose of pneumatic fenders
♦ Ship to ship berthing
Accompanied by a large ship, the risk of two ship berthing at sea
is also increased, especially when the weather changes, accompanied
by wind and waves.Adopt pneumatic fender as side of the buffer, not
only make heavy berthing becomes easy, and improve the efficiency
of the transportation operations. Pneumatic fender is mainly used
for: Ice in the Antarctic ocean fishing ships, large oil tanker
berthing.
♦ Used for terminal dock protection
Of the ship is very large, the cause of berthing impact energy have
multiplied.Inflatable rubber fender because of its high energy
absorption and low reaction force features are widely used.
Operation of floating pneumatic fender
For large tankers,normally 4-6 sets of pneumatic rubber fenders are
hanged at the water line of the ship side. When 4 fenders are used,
2 sets are placed at the front and 2 sets at the rear,they are all
large scale fenders.In case 6 fenders are hanged on the ship side,1
small fender will be placed at ship bow and another small fender at
ship stern.
When fenders are not used,they should be craned to the deck and
placed on the anti-rolling seats.
In recent years,there is a new upsurge of wharf and port
building.Because of the super large ships,the berthing collision
energy is multiplied.Due to the low energy absorption and large
reaction force of previous rubber fenders at the wharf, The ship
side and docks usually may be damaged.The low compression reaction
force property of pneumatic rubber fender conforms to the dock
construction light-weighting trend and protects the ship side from
damage as well.Therefore,Florescence Pneumatic rubber fenders are
widely used in large-scale docks,wharves and offshore platforms.
