Product Description
Pneumatic Rubber Yokohama Fender Price Inflatable Boat Fender Customized Size Bumper Mooring
Floating pneumatic rubber fenders, commonly 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.
Note: Floating pneumatic rubber fenders are sometimes referred to as "Yokohama Fenders" or "Yokohama type fenders" - ISO 17357:2002 Ships and marine technology -- High-pressure floating pneumatic rubber fenders.
Key Features
- 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
- Constructed with multiple synthetic-cord layers and abrasion-resistant rubber
- Consistent performance under rough conditions and cyclic loads
- Minimal maintenance requirements and damage risk
- Available in diameters from 500 mm to 4,500 mm and lengths from 500 mm to 9,000 mm
Construction Components
- Outer Rubber: Protects cord layers and inner rubber from abrasion and external forces with excellent tensile and tear resistance.
- Tire Cord Layers: Reinforcement layer designed to maintain internal air pressure integrity.
- Inner Rubber: Seals the pressurized air within the fender structure.
Technical Specifications
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 guy-rope
Applications
- Ports with extreme tidal variations
- Ship-to-ship lightering operations
- Oil & Gas (typically FSRU)
- Temporary berthing

Advantages
Doowin-Marine pneumatic rubber fenders are manufactured and tested to comply with ISO 17357. Our Yokohama-type pneumatic fenders are produced using Korean manufacturing technology.
- ISO 17357 Compliance: All pneumatic fenders are manufactured and tested to comply with ISO 15375 latest edition.
- Soft Reaction Force: The reaction force doesn't increase sharply, even under excess load conditions, protecting ships and mooring facilities.
- 15 ° Inclined Berthing: Energy absorption doesn't decrease at inclined compression up to 15 degrees.
- Against Shearing Force: Reinforced with strong tire-cord to cope with combined shearing forces.
- Lower Mooring Forces: Safely protects ships and mooring facilities even in rough weather conditions.
- Adaptable to Tide: Floats freely to accommodate tidal range and ship's vertical movement.
- Low Cost Installation: Can be moored simply with guy rope or chain and easily relocated.
- Low Maintenance Cost: Minimal air leakage requires only annual pressure checks.
- Ship Cost Minimization: Packed and shipped in containers or on pallets in vacuumed, folded state.
