Port Fendes Durable Shock Absorption UV Resistant Weatherproof
Description
The Yokohama Rubber Fender is a high-capacity pneumatic fender designed for high-frequency berthing and extreme impact conditions. Its floating design and compressed air chamber provide excellent energy absorption while maintaining a low reaction force to protect both vessel hulls and quay structures. The fender’s multi-layer cord reinforcement ensures durability and prevents deformation under repeated loading, making it ideal for busy commercial ports, container terminals, and ship-to-ship operations where continuous docking cycles occur.
( Case Study: A major East Asian container terminal handling hundreds of large container ships monthly faced rapid wear and tear on conventional fenders, causing frequent maintenance downtime and operational delays. Hongruntong Marine supplied heavy-duty Yokohama pneumatic fenders measuring 3.5 meters in diameter and 6.0 meters in length, with 80 kPa working pressure and reinforced chain-tire nets. Over a 24-month period, the fenders absorbed thousands of berthing events with minimal deformation. Terminal operators reported a 50 percent reduction in fender replacement frequency, smoother docking operations, and significant operational cost savings. The robust performance under high-frequency, high-energy conditions confirmed the suitability of Hongruntong Yokohama fenders for ultra-busy ports. )

Features
Exceptional Energy Dissipation for High Frequency Docking
The fender’s internal air chamber allows progressive compression, effectively absorbing impact energy during frequent berthing events. This prevents stress spikes on vessel hulls and dock structures, maintaining operational continuity in high-traffic ports.
Ultra Resilient Reinforced Cord Layers
Multiple layers of synthetic tire-cord fabric embedded in high-quality rubber provide superior tensile strength and fatigue resistance. This reinforcement maintains the fender’s cylindrical shape and prevents delamination under repeated compression cycles, ensuring long-term stability in high-load environments.
Durable and Weather Resistant Rubber Shell
The external rubber layer is formulated for maximum resistance against ozone, UV radiation, saltwater, and abrasion. The seamless design minimizes wear and tear during repeated docking of large vessels, while optional chain-tire nets provide additional mechanical protection for extreme impact scenarios.
Flexible Deployment and Pressure Adjustment
Hongruntong pneumatic fenders are lightweight and easily installed or repositioned. Air pressure can be adjusted to optimize stiffness for varying vessel sizes and berthing conditions, ensuring consistent energy absorption across multiple operational scenarios.
Applications
High Traffic Container Terminals
Provides critical energy absorption for repeated docking of large container ships and feeder vessels, protecting quay structures and hulls.
