Product Description
Light weight Design Yokohama Fender with Energy Absorption and Low Hull Pressure for Marine Protection
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. They are made of high-quality natural rubber, ensuring excellent elasticity and durability.
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
- Multiple synthetic-cord layers with tough abrasion-resistant rubber for consistent performance
- Minimized maintenance costs and damage risk
- Self-buoyancy and long service life
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 that maintains internal air pressure integrity
- Inner Rubber: Seals the pressurized air within the fender structure
Technical Specifications
Pressure Ratings:

Applications
- Ports with extreme tidal variations
- Ship-to-ship lightering operations
- Oil & Gas (typically FSRU)
- Temporary berthing
Product Advantages
- ISO 17357:2002 Compliant: Manufactured and tested to meet international standards
- Soft Reaction Force: Doesn't increase sharply under excess load conditions
- 15° Inclined Berthing: Maintains energy absorption at angles up to 15 degrees
- Shear Force Resistance: Reinforced with strong tire-cord for combined force resistance
- Tide Adaptability: Floats freely to accommodate tidal range and ship movement
- Low Maintenance: Minimal air leakage requires only annual pressure checks
- Cost Effective: Simple installation and low maintenance requirements
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.
