Pneumatic fenders, also known as Yokohama rubber fenders, are a type of marine fender widely recognized as one of the most effective anti-collision devices in the maritime industry. These air-filled rubber fenders act as a protective buffer between ships and structures during ship-to-ship (STS) or ship-to-berthing (STB) operations. Their ability to absorb significant energy while maintaining low surface pressure makes them an ideal choice for protecting large vessels such as tankers, LPG carriers, offshore platforms, and harbor facilities.
One of the key advantages of pneumatic fenders is their ease of deployment. They can be quickly installed and adjusted according to the specific needs of the application. Additionally, they offer adjustable performance through changes in initial inflation pressure, making them suitable for various tidal conditions. These fenders also help maintain larger clearances between the ship’s hull and the structure, reducing the risk of damage. For heavy-duty applications, optional chain-tyre nets can be added for extra durability, and their low maintenance requirements make them a cost-effective solution.
Pneumatic fenders are commonly used in a wide range of maritime applications, including:
- Tankers and gas carriers
- Fast ferries and aluminum-hulled vessels
- Temporary or permanent installations
- Emergency fendering scenarios
- Stand-off fenders for realigning ships with shore facilities
Below is a technical performance table that outlines the specifications and capabilities of different sizes of pneumatic fenders:
These fenders are manufactured by Yutung, a well-known brand in the marine industry, and are certified by CCS (China Classification Society). They are typically shipped in nude pack, and their specifications can be customized based on customer requirements. Made in China, these fenders are identified by the HS code 8907900090.
