Dock Fender High Wear Resistance Superior Impact Absorption Durable Marine Grade Rubber
Description
Arch Rubber Fender is a robust marine fender system specifically engineered for medium to heavy-duty berthing operations where reliable energy absorption, structural stability, and long service life are critical. Designed with a curved arch profile, this fender effectively distributes reaction forces across a wider contact area, reducing localized stress on both the vessel hull and quay structure.
Manufactured from high-quality natural rubber compounds with enhanced elasticity and abrasion resistance, the Arch Rubber Fender offers excellent performance under repeated compression cycles. The material formulation ensures stable mechanical properties even under harsh marine environments, including exposure to saltwater, UV radiation, temperature fluctuations, and heavy mechanical impact.
The fender is available in a wide range of standard heights, lengths, and fixing configurations, allowing it to accommodate different vessel sizes and berthing conditions. Steel mounting plates and anchor bolts are integrated into the design to ensure secure installation and long-term structural integrity.
In practical operation, the Arch Rubber Fender provides an optimal balance between energy absorption and reaction force, making it suitable for shipyards, commercial ports, tug berths, and offshore facilities. Its simple yet highly efficient structure minimizes maintenance requirements while delivering consistent protection, contributing to safer berthing operations and reduced lifecycle costs.
Case Study
The Arch Rubber Fender system was applied at a coastal shipyard in Southeast Asia that regularly handles multipurpose cargo vessels with displacement ranging from approximately 8,000 to 12,000 DWT. The berth in question is used for frequent docking during vessel construction, repair, and pre-delivery inspection, resulting in repeated berthing impacts at variable approach angles. The shipyard previously experienced uneven wear on conventional fender units, leading to inconsistent energy absorption and increased maintenance requirements, as well as concerns over localized stress on the quay structure during peak operational periods.
To address these challenges, Hongruntong Marine supplied a series of Arch Rubber Fenders specifically configured for the berth’s operational conditions. The fenders were designed with optimized rubber hardness and reinforced steel mounting plates to ensure stable deformation behavior under repeated compression cycles. Installed along a 120-meter quay section in a modular arrangement, the system provided uniform load distribution and improved lateral stability during vessel contact.
Following installation, the shipyard reported a significant improvement in berthing safety and operational efficiency. Impact forces were effectively absorbed, reducing stress on both vessel hulls and quay structures. After more than 18 months of continuous operation, the fenders demonstrated stable elastic recovery with no abnormal wear or permanent deformation observed. Maintenance intervals were extended, and docking procedures became smoother, contributing to reduced downtime and overall cost savings. Based on the consistent performance and positive operational feedback, the same Arch Rubber Fender configuration has since been adopted for additional berths within the facility, confirming its reliability and repeatability for similar shipyard applications.

Features
High Energy Absorption with Controlled Reaction Force
The arch-shaped geometry allows the fender to deform progressively under load, absorbing high levels of kinetic energy while maintaining controlled reaction forces. This characteristic is particularly important for protecting quay structures with limited load-bearing capacity, ensuring effective impact mitigation without transferring excessive stress.
Durable Rubber Compound for Long Service Life
The rubber material is formulated to resist abrasion, fatigue, and environmental degradation. Even under continuous compression and shear forces, the fender maintains its elastic recovery, reducing permanent deformation and extending service life in demanding marine environments.
Structural Stability and Load Distribution
Compared to conventional block fenders, the arch profile provides improved lateral stability during berthing. The wide contact area distributes loads more evenly, reducing localized stress on both vessel hulls and mounting structures, which enhances overall system reliability.
Easy Installation and Low Maintenance
The simple structural design allows for straightforward installation using standard marine-grade fasteners. Minimal moving parts and robust material properties significantly reduce maintenance requirements, resulting in lower operational costs over the fender’s lifecycle.
Applications
Commercial Port Berths
Arch Rubber Fenders are widely used in general cargo, bulk, and multipurpose terminals where vessels of varying sizes berth frequently. Their ability to handle repeated impacts makes them suitable for high-traffic quay walls.
Shipyard Docking and Maintenance Areas
In shipyards, these fenders provide reliable protection during vessel construction, repair, and outfitting stages. They accommodate different hull forms and berthing angles, ensuring safe operations in confined docking environments.
Tug and Service Vessel Berths
For tugboats and service vessels that berth at higher frequencies and variable speeds, Arch Rubber Fenders offer consistent performance and durability, minimizing downtime caused by fender damage.
