Instruction of D2.0L4.5m Yokohama Type Ship Rubber Bumpers Pneumatic Fender BV Approved
Florescence floating fender for ship has the advantages of high energy absorption and reaction force, low cost, long service life, simple installation and maintenance, etc. It is usually used in ship to ship, ship to wharf for barge and docking, which is a new generation product of fender of ships and is popular in the world.
Due to its self-floating characteristics, this floating fender for ship to ship operation is also particularly suitable for installation in docks where the tide level varies greatly. Among them, the filled rubber fender is especially suitable for applications in harsh environments, such as offshore drilling platforms, due to its advantages of maintenance-free and long service life.
Florescence pneumatic rubber fenders is constructed of four parts:
1. Outer rubber
Rubber layer that covers the outside of the fender to protect the cord layers and the inner liner rubber from abrasion and other external forces.
2. Cord layers
Layer made of synthetic-tyre-cord fabric, which maintains the intemal air pressure of the fender.
3. Inner rubber
Liner of a rubber membrane that seals the pressurized air inside the fender.
4. Flange opening
Steel flange which is mounted on the fender, to which an air valve or safety valve can be adapted.
Features of pneumatic rubber fenders
(1) High energy absorption
The amount of energy absorbed is the main technical performance indicators fender instruments. With the ship's tonnage growth, berthing operations, ship collision energy contact quay or other ships also doubled. Huge collision energy must rely on the contact area on the fender and enough to absorb sufficient deformation. Fenders use compressed air as the buffer medium to absorb ship impact energy and have good elasticity.
(2) Ultra low back pressure
The inside air of pneumatic fenders is low pressure gas, the internal pressure increase is very limited during compression deformation. Due to the large contact area, unit pressure acting on the ship hull surface is very low, compared with other fender instruments, is not the common low back pressure.
(3) Inclined contact, good adaptability
Ship must have certain angle which have the possibility of contacting the side of the shore. As the inclined interface of pneumatic fender, its adaptability is much higher than other fender.
(4)Floating performance is good, not subject to tidal influence, fender can be maintained in the ideal level
Pneumatic marine fenders floating on the water surface (more than 50% of the volume), along with the change of position is not relative to the tidal fluctuation. Especially the ship as the waves rolling, cylindrical inflatable fenders with rolling, the friction force is very small. So it will not damage the coating surface of the hull, and also decrease the moving.
(5) Both end fender flange produced by special materials, acid and alkali resistance, oxidation resistance, not easy to rust.
(6)Florescence pneumatic marine fenders install easily and widely used in a variety of ships, large dock and a large variety of tidal dock.
Application of pneumatic rubber fenders
1. Offshore platform
2. Oil and gas tankers
3. Fast ferries and aluminium vessels
4. Temporary and permanent installations
5. Rapid response and emergencies
6. In ports with extreme tidal variations
7. Fishing vessel, transport ship and ocean trawler

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.
1. Pneumatic pressure control in±5% of the rated pressure
2. Test pressure normally, add pressure in a timely manner
3. Avoid contact with sharp objects
4.When Long time not need, should wash to dry, filled with right amount of compressed air, placed in a cool dry ventilated
5.Storage place away from heat, acid and alkali, oil and grease
6.When store floating fender, shall not be folded and piled up
