Pneumatic fenders, also known as Yokohama rubber fenders, are a key marine fender system used globally for ship-to-ship (STS) and ship-to-berth (STB) operations. These air-inflated rubber fenders act as a protective buffer to absorb impact energy and reduce the risk of damage during docking or collision. With their ability to handle high energy absorption while maintaining low surface pressure, pneumatic fenders have become an essential component in protecting large vessels such as tankers, LPG carriers, offshore platforms, and port infrastructure.
**Key Features:**
- Easy and quick deployment
- Minimal reaction force and hull pressure
- Adjustable performance through initial pressure control
- Suitable for both large and small tidal areas
- Provides consistent clearance between the ship and structure
- Optional chain-net systems for heavy-duty applications
- Low maintenance requirements
**Applications:**
- Tankers, gas carriers, and bulk cargo ships
- Fast ferries and aluminum-hulled vessels
- Temporary or permanent installations
- Emergency fendering solutions
- Stand-off fenders for realigning ships with shore facilities
