Arch Rubber Fender High Energy Absorption Long Service Life Easy Installation
Description
The Arch Rubber Fender is a heavy-duty dockside protection system engineered to absorb high impact energy during vessel berthing while maintaining low reaction forces on quay structures. Its arch-shaped body, molded from reinforced marine-grade rubber, provides a stable and efficient deformation pattern that ensures reliable protection for ships and docks under various berthing conditions. The unique “V” profile allows for optimal load distribution and minimal hull pressure, making it one of the most efficient solid-type fenders in the marine industry.
Hongruntong’s Arch Rubber Fenders are designed for long-term performance in demanding port and offshore environments. Manufactured from high-strength natural and synthetic rubber compounds, they resist ozone, UV radiation, saltwater, and mechanical wear. The compact structure enables easy installation and alignment on both new and existing quay walls, piers, and jetties. The fenders can be installed vertically or horizontally and are often combined with UHMW-PE face pads or frontal panels for enhanced friction control and durability.
Case Study: Port Modernization Project – Southeast Asia
A busy cargo terminal in Southeast Asia was facing excessive hull damage and quay wall wear due to aging cylindrical fenders that could not handle frequent docking impacts from 30,000 DWT container ships. The port authority required a more compact yet highly durable fendering system with improved energy absorption and lower reaction force.
Hongruntong Marine designed and supplied Arch Rubber Fenders type V800H, installed along a 250-meter section of the berth. Each unit featured a high-density rubber body with a hardness rating of 65±5 Shore A and integrated steel backing plates. After 12 months of continuous service, port engineers recorded a 38% reduction in hull contact stress and no structural damage to the quay wall. Maintenance frequency dropped significantly, and the terminal achieved smoother, faster berthing operations.
The success of this installation demonstrated the superior reliability of Hongruntong Arch Fenders in high-traffic ports with limited maintenance opportunities, reaffirming their reputation as a durable and cost-effective solution for modern maritime infrastructure.

Features
Optimized Energy Absorption with Low Reaction Force
The curved V-shaped design efficiently transforms kinetic impact energy into controlled deformation, minimizing reactive loads on dock structures. This ensures stable berthing for vessels of varying displacements, reducing structural fatigue and protecting both ships and port assets. The fender maintains consistent energy performance even after thousands of compression cycles.
Reinforced Rubber Compound for Superior Durability
Each fender is manufactured from premium-grade rubber blended with synthetic polymers for enhanced tear resistance, elasticity retention, and environmental protection. The compound formulation provides exceptional resistance to ozone, UV radiation, seawater, and aging, extending service life even in tropical or polluted marine atmospheres.
Compact Design and Easy Installation
Arch Fenders are lightweight and modular, allowing quick and secure installation on both flat and curved quay walls. Standard anchor bolts and galvanized steel plates provide strong attachment, while optional UHMW-PE face pads reduce friction and surface wear. This compact structure makes them ideal for retrofit or expansion projects with limited space.
Consistent Performance Across Temperature and Tidal Variations
The rubber’s stable elasticity ensures reliable performance in extreme climates—from sub-zero Arctic temperatures to high tropical humidity. Even under tidal movement, the fender maintains consistent energy absorption and compression recovery, ensuring long-term protection with minimal maintenance requirements.
Applications
Commercial Ports and Container Terminals
Provides reliable impact protection during frequent docking of cargo ships, bulk carriers, and container vessels. The arch shape ensures efficient energy distribution, protecting quay walls from repetitive berthing stresses.
Fishing Harbors and Small Craft Jetties
Ideal for smaller vessels requiring compact, cost-effective, and durable fendering solutions. Its flexible installation options make it perfect for wooden or concrete docks with variable draft conditions.
Industrial Shipyards and Offshore Support Facilities
Used for dry docks, repair berths, and supply bases where frequent vessel contact occurs. The fender’s high abrasion resistance and stable performance make it suitable for demanding operational cycles.
