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.
