High Impact Absorption and Controlled Reaction Force
The fender’s internal air chamber provides exceptional energy absorption capacity, compressing progressively under impact. This feature ensures a low and predictable reaction force that protects both the ship hull and the berth structure. The controlled deflection characteristics enable safe docking even under oblique approach angles or high berthing velocities.
Multi Layer Reinforcement with Synthetic Tire-Cord Fabric
Hongruntong employs advanced cord fabric technology with high tensile strength and fatigue resistance. Multiple cord layers are arranged in a bias angle structure, preventing internal expansion and maintaining cylindrical form under pressure. This robust reinforcement extends the service life and guarantees stability through repeated compression cycles without delamination or tearing.
Resilient Outer Rubber Shell
The outer cover uses premium marine-grade rubber compounds that resist ozone, saltwater, oil, and UV degradation. The shell maintains flexibility in extreme environments, from tropical humidity to arctic cold. Its abrasion-resistant formulation minimizes surface wear, ensuring reliable long-term use even in high-contact applications like ship-to-ship (STS) operations.
Effortless Handling and Flexible Deployment
Yokohama pneumatic fenders are lightweight compared to solid alternatives and can be easily towed, suspended, or relocated. The simple inflation system allows quick adjustment of air pressure to adapt to different vessel sizes. Optional chain and tire nets offer additional protection in heavy-duty applications without compromising flexibility or performance.
Applications
Oil and LNG Terminals
Provides critical impact protection for high-value assets during berthing of large oil and gas carriers, preventing hull damage and ensuring operational continuity.
Shipyards and Floating Docks
Used for docking new builds, vessel repair, or painting, offering soft contact that minimizes hull surface stress.
Temporary or Emergency Berthing Systems
Portable design allows fast setup for emergency mooring or temporary berthing points during construction or port upgrades.

FAQ
1. How is air pressure monitored in operation?
Each fender includes a pressure valve and gauge for regular inspection. Pressure should be checked monthly to maintain optimal performance.
2. What’s the advantage over foam or solid fenders?
Yokohama fenders provide higher energy absorption and lower reaction force, with the ability to recover shape instantly after impact.
3. Are chain tire nets necessary for all models?
They are recommended for heavy-duty berthing or STS operations to enhance abrasion resistance and extend lifespan.
4. Can fenders be used for offshore floating structures?
Yes, Hongruntong designs custom floating fender systems for offshore platforms and FPSOs operating in open seas.
5. What is the recommended storage procedure?
Store inflated under nominal pressure in a shaded, dry location. Avoid exposure to sharp objects and direct sunlight to preserve rubber elasticity.
