Storm Resistant Marine Fenders Heavy Load Corrosion Resistant Flexible Design

Storm Resistant Marine Fenders Heavy Load Corrosion Resistant Flexible Design

Description

Roller fenders are advanced marine protective systems designed to safeguard both vessels and dock structures from impact during berthing operations. They feature a rotating cylindrical design that allows the fender to roll upon contact with the vessel, distributing kinetic energy evenly and minimizing lateral forces. Constructed from high-strength synthetic rubber reinforced with corrosion-resistant steel cores, roller fenders are engineered to withstand harsh maritime conditions including saltwater exposure, UV radiation, and extreme temperature fluctuations.

These fenders are particularly suitable for busy container ports, oil and gas terminals, ferry terminals, and bridge piers where frequent docking occurs. Their modular design allows individual rollers to be replaced without disassembling the entire system, ensuring minimal disruption to port operations. Dimensions, roller spacing, and mounting systems can be customized to accommodate different vessel types, berth sizes, and operational conditions.

Case Study

In 2019, a high-traffic container port in Australia sought to upgrade their dock protection system for ultra-large container vessels (ULCVs) with capacities exceeding 18,000 TEU. The port previously experienced significant hull wear and minor dock damage due to repeated high-speed berthing. Hongruntong Marine was contracted to provide a custom roller fender solution to improve vessel safety and operational efficiency.

The engineering team conducted a thorough site survey, analyzing vessel sizes, berthing speeds, tide variations, and dock geometry. Customized roller fenders with 1.8-meter diameter rollers and high-strength steel cores were fabricated. The rubber compound was specially formulated for superior elasticity and long-term UV and saltwater resistance.

During the first year of operation, the port reported a 65% reduction in minor hull damages and smoother docking operations, significantly reducing the need for tug assistance. The fender system maintained structural integrity despite heavy daily traffic and extreme weather including strong winds and storms. The modular design allowed rapid replacement of worn rollers without interrupting port operations. This project confirmed that roller fenders could provide reliable protection for large vessels while improving overall port efficiency.

Specifications

Features

High Energy Absorption

The rotating roller design ensures kinetic energy is absorbed efficiently and distributed evenly across the fender surface. Laboratory testing demonstrates energy absorption exceeding 95% for ultra-large container vessels. This minimizes localized stress on both the dock and vessel hulls.

Extreme Environmental Resistance

Marine-grade rubber and galvanized steel cores resist UV radiation, saltwater corrosion, and wide temperature ranges. The fenders maintain elasticity, resilience, and energy absorption performance over long-term operation even under harsh environmental conditions.

Modular and Low Maintenance

The fender’s modular construction allows individual rollers to be replaced without removing the entire system, reducing downtime and maintenance costs. Rolling action reduces wear on the rubber surface, prolonging service life.

Customizable Design for Vessel and Dock Types

Roller fenders can be customized in diameter, length, and spacing to accommodate different vessel types and dock configurations. Mounting systems are adaptable for fixed piers, floating docks, and bridge structures, ensuring optimal performance in various applications.

Applications

Ultra Large Container Vessel Berths

Suitable for high-volume container ports where large vessels dock frequently. Provides energy absorption and prevents hull and dock damage.

Ferry and Passenger Terminals

Protects smaller vessels in high-frequency docking scenarios, ensuring smooth alignment and safe berthing.

Bridge and Harbor Piers

Absorbs lateral and vertical forces from vessel contact, protecting structural integrity while maintaining vessel alignment.
