Pneumatic Rubber Marine Fender 0.5m-4.5m Maritime International Fenders
Floating pneumatic rubber fenders, also known as Yokohama fenders, are constructed from synthetic-cord-reinforced rubber sheets with compressed air inside. This design enables them to float on water and serve as effective 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. Developed through continuous R&D, these fenders meet the needs of large-scale vessels and ports.
- Lightweight design for easy handling and installation with guy-rope or guy-chain
- Maintains energy absorption level under inclined compression up to 15 degrees
- Provides low and even hull pressure distribution
- Multiple synthetic-cord layers with tough abrasion-resistant rubber
- Minimized maintenance costs and damage risk
- Self-buoyancy and long service life
- Outer Rubber: Protects cord layers and inner rubber from abrasion with excellent tensile and tear resistance
- Tire Cord Layers: Reinforcement layer that maintains internal air pressure integrity
- Inner Rubber: Seals the pressurized air within the fender structure
Pressure Ratings:
- Pneumatic 50 (P50): Initial internal pressure 50kPa
- Pneumatic 80 (P80): Initial internal pressure 80kPa
Fender Types:
- Type I - Net Type: Covered with 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 chain or rope
