Rolling Fenders UV Resistant Saltwater Proof Easy Install Long Lifespan

Description

Roller fenders are engineered solutions designed to protect vessels and docking structures by efficiently absorbing kinetic energy during berthing. Unlike traditional fixed or rubber block fenders, roller fenders incorporate a rolling mechanism, allowing them to rotate with vessel movement. This design minimizes lateral forces on the ship hull, reduces friction, and distributes energy evenly across the fender body. Constructed from high-strength marine-grade rubber reinforced with galvanized steel cores, roller fenders demonstrate exceptional durability, environmental resistance, and low maintenance requirements.

The roller fender system is suitable for a wide range of applications, from high-traffic container ports to offshore oil terminals and bridge piers. Key performance attributes include high energy absorption, resistance to extreme weather conditions, and customizable dimensions to accommodate various vessel sizes. Their modular structure allows for easy replacement and repair of individual rollers, which is critical for maintaining uninterrupted port operations.

Case Study

In 2022, Hongruntong Marine supplied and installed a series of roller fenders at a major European oil terminal in Rotterdam, Netherlands. The terminal frequently handles crude oil tankers ranging from 50,000 to 150,000 DWT. Prior to the installation, the port experienced frequent minor damages to tanker hulls during docking, leading to increased maintenance costs and occasional operational delays.

The Hongruntong Marine team conducted an extensive site survey, considering berth structure, vessel dimensions, berthing speed, and environmental factors such as tidal variation and prevailing winds. Based on this analysis, customized roller fenders with 1.5-meter diameter rollers, reinforced cores, and specially formulated rubber compounds were designed to meet the terminal's high-impact and environmental resistance requirements.

Following installation, operational performance was closely monitored. Within the first year, the terminal reported a 50% reduction in docking impact forces, complete elimination of minor hull damages, and smoother vessel berthing with reduced tug assistance. The rolling fenders performed reliably under extreme conditions, including winter temperatures below freezing, high winds, and heavy rain. Port operators noted a significant reduction in overall maintenance costs and an increase in operational efficiency. This case highlights the roller fender’s ability to provide consistent, reliable protection even under heavy-use conditions, ensuring both vessel and dock safety.

Specifications

Features

Superior Energy Distribution

Roller fenders utilize a rotating cylindrical design to evenly distribute forces during vessel contact. This reduces localized stress points, preventing damage to both the dock and hull. Laboratory impact tests confirm that the system can absorb up to 95% of the kinetic energy from large vessels berthing at standard speeds. The energy distribution mechanism also ensures minimal rebound, maintaining vessel stability during docking.

Enhanced Environmental Resistance

The rubber formulation used in these fenders is engineered to resist UV radiation, saltwater corrosion, and extreme temperature variations. This ensures that the fender maintains elasticity, resilience, and overall structural integrity even after prolonged exposure to harsh marine conditions. The steel cores are treated with multi-layer anti-corrosion coatings to prevent rust and degradation over decades of operation.

Modular Low Maintenance Design

The modular nature of the roller fender allows individual rollers to be replaced without disassembling the entire system, significantly reducing maintenance downtime. The rolling mechanism minimizes friction and wear on the rubber surface, extending the fender’s lifespan. Routine inspections are simple and cost-effective, ensuring that port operations are not interrupted.

Customizable Dimensions and Mounting

Roller fenders can be tailored in terms of diameter, length, and mounting type to suit different berth configurations and vessel types. Options are available for installation on fixed piers, floating docks, and bridge piles. Customizable spacing and roller diameter allow ports to optimize energy absorption, ensure safe berthing, and protect dock infrastructure under varying traffic loads.

Applications

Oil Terminals and Tanker Berths

Roller fenders provide robust protection for large crude and product tankers, reducing impact forces and hull stress during berthing. Their environmental resistance ensures reliable performance even in extreme weather conditions.

Commercial Container Ports

Ideal for busy container terminals handling high-volume traffic, roller fenders allow faster turnaround by minimizing tug assistance and preventing vessel and dock damage.

Bridge and Harbor Piers

By absorbing lateral and vertical forces, roller fenders safeguard pier structures from repeated collisions while maintaining vessel alignment and operational efficiency.
