Floating pneumatic rubber fenders, also known as Yokohama fenders or Yokohama-type pneumatic fenders, are constructed from synthetic-cord-reinforced rubber sheets with compressed air inside. The internal air enables them to float on water and serve as shock absorbers between ships (ship-to-ship) or between ships and berthing structures during docking operations.

All Doowin Marine Yokohama-type floating pneumatic rubber fenders are manufactured and tested to fully comply with ISO 17357 standards. These fenders can be easily handled and installed with guy-ropes or guy-chains due to their lightweight design. They maintain energy absorption levels under inclined compression up to 15 degrees while providing low and comparatively even hull pressure.

We offer two common types of Pneumatic Rubber Fenders:

• Type I - Net Type: Covered with a chain net, wire net, or fiber net for small size fenders
• Type II - Sling Type: Features lifting devices on each end for connection with guy chains or ropes, offering easy handling with lightweight construction

Our floating pneumatic rubber fenders consist of an outer rubber layer, reinforcement synthetic-tire-cord layer, and inner rubber, all vulcanized firmly together.

• Outer Rubber Layer: Provides superior protection for cord layers and inner rubber, with sufficient tensile and tear resistance to withstand harsh weather conditions and severe usage.
• High Quality Synthetic-Tyre-Cord Layer: Reinforced to maintain internal air pressure, with inner rubber layer sealing the pressurized air inside.
• Safety Valve: Standard on fenders ≥2500mm diameter (available on smaller fenders upon request) for releasing excess internal pressure.
• Chain and Tire Net Option: Provides extra protection for rubber fender body using truck tires, fiber net, or aircraft tires.
