Pneumatic Rubber Fender-Dock Bumpers Native Top 2 Supplier of Rubber Products

Dock bumpers also called rubber fender ,pneumatic fender, marine fender, yokohama fender, made by rubber & multi layer of rubber-dipped tyre fabric, is a leading anti-collision device for marine application in the world today. Dock bumpers have become an ideal ship protection medium against collision among ship-to-ship (STS), ship to quay (STQ) and ship-to-berthing (STB), they are widely used for large tankers, vessels, docks, harbor wharfs and ocean platforms. Our dock bumpers can be delivery deflated and inflated according to customers requirement and shipment situation.

The "yokohama pneumatic rubber fender"is developed in 1958 based on a rubber company's technology for automible tires and rubber aircraft fuel tanks.Progress in the development of such floating pneumatic rubber fenders is closely related to the 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,more than 45.000 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.

Pneumatic Rubber Fender-Dock Bumpers

Advantages during inclined berthing

During berthing, the initial contact with the dock is usually at an oblique angle and that places a lot of pressure on both surfaces (the dock and the ship).

For typical solid rubber fenders, at inclined compression which is usually the case, energy absorption decreases considerably. Therefore, it is not unusual to see solid fenders used are larger in sizes. On the other hand, pneumatic fenders’ energy absorption maintains at a relatively high level despite inclined compression. Due to a more evenly distribution of load pressure, the torque performance against the dock is usually smaller when compared to conventionally designed solid fender systems.

Stronger against shearing force

After making contact with the dock, the vessel is usually slowly moved to the optimum mooring position. This action exerts high shearing force and compression on the surface of fenders. Most solid fenders are severely damaged due to such forces as they are not designed to withstand strong shearing forces and friction that way. However, it depends on the designs/types of solid fenders. For example, MAX frontal pads for solid fenders are designed to tackle this issue and protect the fenders from shearing forces, in which the surface of fenders do not make contact with the ship.

Relatively safe even during excess load

Generally speaking, all fenders should be used within the impact load limit. However in real life situations, it is common to see that fenders often accidentally receive excess loads. When that happens, the fortunate thing about a pneumatic fender is that the reaction force does not increase sharply under excessive load. In contrast, solid fenders’ reaction forces tend to spike sharply under excessive load conditions and damage the ship during the mooring process. This is also helped by pneumatic type fenders’ characteristic that enables a more uniform distribution of stress.

Advantages during crucial weather conditions

During crucial weather conditions when the wave action is severe, mooring processes are further complicated due to up and down unbalanced action at the quay. This exerts a higher shearing force on the fenders and the frequently change in forces during mooring under such weather conditions will cause fatigue on typical solid type fenders. However on the other hand, pneumatic fender’s flexible contact area and large allowable deflection characteristics minimise fatigue during such situations. In fact, for seas with rough situations or frequent bad weather conditions, pneumatic types may be a better option than solid type fenders as it may display a longer life span.

Deterioration in performance minimised

Aging and fatigue often cause fenders to deteriorate in terms of performance. However, due to its air filled body and highly elastic material, such issues are minimised. Solid rubber fenders or foam fenders depend more on the hardness of the material and such dependance may result in decrease in energy absorption performance after years of usage and temperature change. On the other hand, as long as basic maintenance and air pressure control is maintained, pneumatic fenders remain optimum performance even at extremely low temperature down to -50 Degree Celsius or even during high fluctuations.

Tide adaptation

Pneumatic fenders are primarily floating-types, which means the fenders float on the water in an unrestricted vertical plane corresponding to the tidal range and ship’s vertical movement. Therefore, fender energy absorption always take place at the most optimum position.

Simple installation and low maintenance cost

Pneumatic fenders can be installed simply by means of ropes or chains at minimal extra cost. Transfer or removal is also really flexible and easy for such floating type fenders. Maintenance for pneumatic type fenders include annual checks on internal air pressure, physical condition of the chain net and fender surface. Usually chain nets have a life span of about 3 to 4 years, depending on usage.
