Benefits of Hydro Pneumatic Fender

High Energy Absorption, Low Reaction Force – They protect hulls without pushing back hard.

Adapt to Tidal Changes – Their floating design adjusts with the water level.

Simple Installation and Maintenance – They are lightweight and easy to manage.

Versatile Use – Suitable for ports, offshore platforms, and ship-to-ship transfers.

Long Lifespan – Their materials resist harsh weather and saltwater.

The Structure And Working Principle Of Hydro Pneumatic Fender

Structure: Hydro-pneumatic fenders consist of a flexible outer shell and an internal chamber that is partially filled with water and air. The counterweight helps to maintain the vertical position of the fender.

Working Principle: When a vessel comes into contact with the hydro-pneumatic fender, the impact force is absorbed by the compression of both the water and air inside the chamber. The water provides damping and shock absorption, while the air allows for some flexibility and movement. The counterweight ensures that the fender remains upright and in position, providing consistent protection to the vessel’s hull.

Application of Hydro Pneumatic Fender

Automated Ports

Ideal for container terminals and smart harbors requiring precise vessel control and rapid fender deployment.

Tanker & LNG Ships

Enhanced safety for high-density vessels carrying hazardous cargo.

Offshore Floating Structures

Protects FPSOs, wind turbines, and subsea pipelines from anchor strikes or collisions.

Marina & Yacht Clubs

Compact, easy-to-maintain solution for smaller vessels and crowded docks.

Military & Research Vessels

Robust performance for defense ships, submarines, and polar research expeditions.

FAQ

Q: What is pneumatic rubber fender?

A: Pneumatic fenders (also known as Yokohama fenders) are a very common type of floating fenders used to protect ships and vessels during ship to ship operations. They are also commonly used in seaports on quays to protect vessels during berthing operations.

Q: What are the different types of rubber fenders?

A: There are a lot of fender types that can be used on the port, for instance: cylindrical type fender, V-type, A-type, M-type, super cell, and super cone.

Q: What is the pressure of pneumatic fenders?

A: According to ISO 17357, high pressure pneumatic fenders have an initial pressure of 50 kPa or 80 kPa to provide the prescribed GEA for each fender size and grade. It is a common misconception in the maritime industry that launch- ing airbags are similar to pneumatic fenders.

Q: What is the best material for fender?

A: Natural rubber is highly durable and the addition of SBR grants this product excellent tensile strength while also making the fender resistant to tearing under pressure. To ensure that a fender functions as efficiently as possible it needs to be able to maintain it's shape, even after absorbing the heaviest of impacts.

Q: What size are pneumatic rubber fenders?

A: Pneumatic fenders are available from 500 mm to 4,500 mm in diameters, and from 500 mm to 9,000 mm in length. All sizes of pneumatic rubber fenders are available as sling-type or with a heavy-duty chain & tire net.

Q: How Often Should Rubber Fenders Be Replaced?

A: On average, rubber fenders should be replaced every 10 years. However, this is dependant on a variety of factors, such as the application and the environment in which it is used, the rubber material that has been used for the fenders, the quality of the fender, the level of damage the fender has incurred and the maintenance history of the rubber fender. As the durability of every rubber fender is unique, they should be inspected regularly, and maintenance should be performed to maximise longevity.
