Arch Fenders for Impact Energy Conversion and Protection of Vessels and Docks in Port Facilities with High Traffic

Arch Fender

Arch Fenders are being widely used in port facility due to their high energy absorption,low reaction force and stable performance as well as high durability with simple structure.They are particularly useful for vessels with high allow- able hull pressures and limited mounting space.

Functionality

Impact Absorption
One of the primary functions of an arch fender is to absorb the impact energy generated when a ship approaches and touches a dock or another object. When a vessel makes contact, the arch fender compresses, converting the kinetic energy of the impact into elastic potential energy within the fender material. This compression action significantly reduces the force transmitted to the ship and the structure it is approaching, minimizing the risk of damage to both.

Vibration Damping
In addition to impact absorption, arch fenders also help dampen vibrations. In a marine environment, ships are constantly subject to various forces such as waves, currents, and wind. These forces can cause the vessel to vibrate, which may lead to wear and tear on the hull and other components. The arch fender's flexible nature helps to reduce these vibrations, providing a more stable and comfortable environment on board.

Proven In Practice

Initially established as Qingdao Luhang Marine Airbag Factory in 1988 and changed to Qingdao Luhang Marine Airbags and Fenders Co.,Ltd in 2011, Qingdao Luhang had been devoted itself to developing and manufacturing marine airbags and marine fenders for more than 2 decades.

The factory area is 56,000m² with building area of 21,000m². The company has registered capital of USD 3 million and fixed asset of USD1.2 billion. We have a full line of production equipment: rubber mixing machine, rubber roller machine, the China biggest vulcanization tanks, the biggest Press Inspection Machine, EVA foam processing machine, Foam shaping machines and SPUA spraying machine.

Through these years' development, we have full range of marine airbags and marine fenders:

Ship Launching Airbags for ship launching and docking in shipyards

Marine Salvage Airbags for salvaging sinked vessels or refloating objects from under water

Other Airbags for special usage

Pneumatic Rubber Marine Fenders for ships and docks berthing

Foam Filled Marine Fenders for ship and docks berthing

Fixed Dock Rubber Fenders for docks and wharfs

Marine Buoys

From the begginning we have been focusing on technological innovation. With a team of experienced technicans and engineers, we have developed some high tech marine products and got some petents. We have been approved as a supplier of Navy products.

Quality is our life line. We provide service of “three guarantees” (returning, repairing and replacing) on all our products in case of any defects due to the problems of material,manufacturing, performance under conditions of normal operation and maintenance.
