Combination of Hydraulic and Pneumatic Components:
Hydro-pneumatic fenders typically use a combination of air (pneumatic) and liquid (hydraulic) in their construction. The air portion helps with flexibility and shock absorption, while the liquid section provides increased energy absorption and stability.
The pneumatic section maintains the fender’s shape and allows for inflation to a specific pressure, while the hydraulic system (usually oil or water) helps to further absorb and dissipate the energy during impacts.
Higher Energy Absorption:
Due to their hybrid nature, hydro-pneumatic fenders are able to absorb significantly higher energy than traditional pneumatic fenders. They are often used in locations where large vessels dock and require higher levels of protection, such as oil tankers, large container ships, and other heavy-duty applications.
Reduced Reaction Force:
These fenders typically have lower reaction forces than conventional fenders, which reduces the stress placed on the structures or vessels involved in docking. This makes them ideal for use in areas where minimizing damage to both the ship and the dock is crucial.
More Uniform Pressure Distribution:
The combination of hydraulic and pneumatic elements helps distribute pressure more evenly across the fender’s surface, leading to less wear and tear over time and increasing the fender’s overall lifespan.
Flexible in Design:
Hydro-pneumatic fenders can be designed to different sizes and specifications based on the needs of the port or vessel. They are adaptable to various docking situations and can be customized to meet the specific impact energy levels or vessel types.
Advanced Control Systems:
Many hydro-pneumatic fenders are equipped with advanced control systems that monitor internal pressure, allowing for adjustments in real-time to optimize their performance. These systems can automatically adjust the pressure in the hydraulic or pneumatic chambers based on the specific conditions of the docking environment.
