Floating pneumatic rubber fenders, also known as Yokohama fenders, are made of synthetic-cord-reinforced rubber sheet with compressed air inside. The internal air enables them to float on water and absorb shock between ships (ship-to-ship) or between ships and berthing structures. All Doowin Marine Yokohama-type floating pneumatic rubber fenders are manufactured and tested fully compliant with ISO 17357.
There are two common types of our 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, without protection net for easier handling
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 with high tensile and tear resistance to withstand weather conditions and severe usage
- High Quality Synthetic-tire-cord Layer: Maintains internal air pressure while the inner rubber layer seals the pressurized air
- Safety Valve: Standard on fenders ≥2500mm diameter (optional for smaller sizes) to release excess internal pressure
- Chain and Tire Net: External protection using truck tires, fiber net, or aircraft tires for enhanced durability


All materials comply with ISO 17357:2014 standards for floating pneumatic rubber fenders.
