(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. Aohai rubber ship fender 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 sea inflatable 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 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.   Our Advantages Round Boat Bumper Advantages
1. Advantage at inclined berthing Ship usually make initial contact with the dock or another ship on STS operation at oblique angle. Under 15 degrees at inclined compression, the energy absorption of pneumatic fenders doesn’t decrease. The foam fender has a less decrease than solid fenders. 2. Resistance for shearing force Because of the special shape of semicircle end, it provide the best resistance against shearing force when the ship shift to the correct mooring position 3. Low reaction force The soft reaction force of floating fenders cannot lead to damage the ship and mooring facilities. The increase of reaction force of Floating Fender is not sharply. Its performance is better than solid Rubber Fender. And it’s ruinous for the ship and mooring facilities. 4. Most economical fenders system The floating fenders have simple construction than the solid rubber fenders system. This simple structure ensure the economical of cost. Meanwhile, because of the floating fenders can float on the water, thefloating fenders installationfloating fenders can be installed by a guy Chain or rope. So it has the advantages of simple and low installation. The use of best material and Accessories ensure the low maintenance cost. 5. Adaptable to the tide The floating fenders can float on the water surface depend on the change of tide. So it’s the best choice for the port or quay with huge tide change. Floating fenders also can be used for the ship-to-ship operation discretionarily.
Floating Fenders Selection Procedure The fender selection should consider the operation condition: ship-to-ship or ship-to-quay. The basically process is to calculate and compare the energy absorption of floating fenders with berthing energy. The quick reference is as per the OCIMF Table, to do the fender selection tentatively. If the energy absorption of the tentative selected fenders is larger than the calculated berthing energy, it means that a suitable fender selection has been made. If the fender energy absorption capacity is less than the calculated berthing energy, the selected fender should be upgraded, and selected again. Herein is the selection process of ship-to-ship operation. Contact us to know more about the ship-to-jetty operation.   Performance Table Size and Performance of Round Boat Bumper The Round Boat Bumper can be used for the ship-to-ship operation ad ship-to-dock operation. The large floating fenders are usually floated at the water line as primary fenders to absorb impack energy at berthing and keep proper stand-off distance between ships and dock. The Round Boat Bumper can be hanged to the ship and dock by guy chain or gay rope connect with the shackles and anchor.
