Fendercare Ship Floating Pneumatic Rubber Marine Fender for Boat

Product Specification

 Fendercare Ship Floating Pneumatic Rubber Marine Fender Boat Fenders

Pneumatic marine fender which is made of synthetic-cord-reinforced rubber sheet with compressed air inside to enable it to float on the water and work as a shock absorb between two ships (ship-to-ship), or between ships and berthing structures when they come alongside each other on the water.

Structure of pneumatic rubber fender

1. Outer Rubber
Cover outside on the ball of rubber layer, which is used to protect skeleton material and inner rubber ball from damage of external force.
2. Synthetic cord reinforced rubber layer
Reinforced cord rubber layer is composed of winding synthetic cord layer, it is mainly used for maintain the internal air pressure.
3. Inner Rubber
On the ball inside the rubber layer, which is used to prevent air leakage and control the ball pressure.
4. End Flange
The metal parts at both ends of fender, which can be fitted with charging valve and safety valve

Features of pneumatic rubber fender

(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.

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.

(4) Both end fender flange produced by special materials, acid and alkali resistance, oxidation resistance, not easy to rust.

(5) Florescence pneumatic marine fenders install easily and widely used in a variety of ships, large dock and a large variety of tidal dock.

1.Low surface pressure: with low reaction and high energy absorption rate.

2.Low transportation costs: pneumatic fenders can be deflated and folded for transport.

3.Easy operation: Easy of handling and good buoyancy, with easy installation & maintenance free.

4.Excellent performance: It is with exceptional compressibility and elasticity.

5.Application: marine fender is apt with the Large and small tides, which is suitable for areas with tidal differences.

Test of ship pneumatic fender

1. Material test for rubber
The material test of the outer rubber and the inner rubber shall be conducted in accordance with the physical properties of inner and outer rubber required by ISO 17357:2002
2.Dimensional inspection
The dimension of all the fenders shall be inspected at the initial internal pressure and the results shall be within the following tolerances:
- length: +10%, -5%;
-diameter: +10%,-5%
3.Air-leakage test
The air-leakage test shall be conducted on all the fenders at initial pressure for more than 30 min, and the test results shall
confirm that there is no air leakage.
4.Hydrostatic-pressure test
The hydrostatic-pressure test shall be performed for 10 min at the hydrostatic-pressure shown in "test pressure at 0% deflection". Maximum temporary elongation: 10%

Application of pneumatic rubber fender

Pneumatic marine fenders are suitable for many applications including:

*Tankers, Gas Carriers and Bulk Cargo Ships;

*Fast ferries and aluminum hulled vessels;

*Temporary of permanent installations;

*Rapid response and emergency fendering;

*As stand-off fenders to realign ships with shore facilities.

Advantages of pneumatic marine fender

*Easy and fast to deploy;

*Very low reaction and hull pressure;

*Performance adjustable by varying initial pressure;

*Suitable for areas with large or small tides;

*Maintains large clearances between hull and structure;

*Optional chain-tyre nets for heavy duty applications;

*Low maintenance.
