    Boat Fender Lightweight Structure Strong Flexibility Weather Resistant


    Description


    The Pneumatic Rubber Fender is a sophisticated air-inflated fender system specifically engineered to mitigate the impact between vessels and docking structures or other vessels. Its unique combination of an elastic rubber outer layer and a multi-layer high-tensile cord reinforcement provides excellent deformation capacity, energy absorption, and reaction force control. The fender’s air chamber acts as a compressible medium, enabling consistent cushioning even under repeated and heavy impact scenarios, making it suitable for both inland and offshore applications.


    Hongruntong Marine’s pneumatic fenders have been rigorously tested under ISO 17357-1:2014, ensuring compliance with international safety and quality standards. They are designed to function effectively under extreme environmental conditions, including high wind loads, waves, and temperature variations. The modular design allows integration with tire-chain protective nets, enhancing abrasion resistance while simplifying maintenance.


    Case Study – Container Terminal Upgrade in Rotterdam, Netherlands


    In 2023, a major container terminal in Rotterdam faced challenges accommodating larger Post-Panamax vessels. Existing fixed fender systems were unable to handle increased berthing loads and were causing hull scratches and minor structural damages. The port authority commissioned Hongruntong Marine to provide a customized solution using 1.8 m diameter, 60 kPa pneumatic rubber fenders.


    A team of engineers conducted extensive simulations, including Computational Fluid Dynamics (CFD) modeling of tidal movements and vessel sway during berthing. The fender system was optimized to absorb up to 2200 kN·m of kinetic energy while maintaining a low reaction force below 850 kN. Installation included a tire-chain protective net to withstand container loading equipment impacts.


    After six months of operation, data logging from integrated pressure sensors confirmed consistent performance under high-frequency berthing operations. Terminal operators reported a 30% reduction in hull impact incidents and minimal maintenance requirements. Due to the success of this deployment, the port authority expanded the installation across three additional berths, making Hongruntong fenders the standard for large container operations.


    This project demonstrates the adaptability, durability, and reliability of Hongruntong pneumatic fenders in modern high-density port environments, addressing both safety and efficiency challenges.

    Features


    High Energy Absorption with Controlled Reaction Force
    Hongruntong pneumatic fenders utilize optimized internal air pressure and geometric design to achieve a superior ratio of energy absorption to reaction force (EA/RF). This allows vessels to berth safely with minimal hull stress while maximizing impact mitigation. Laboratory and field tests demonstrate that even under repeated heavy berthing cycles, the fender maintains structural integrity and consistent performance.


    Durable Multi Layer Reinforcement
    The fender incorporates multiple layers of high-tensile synthetic tire cords arranged in cross-ply orientation, providing high resistance to internal pressure fatigue and preventing delamination. The design supports long-term exposure to cyclic loads without compromising structural integrity, ensuring service life exceeding 12 years under normal operating conditions.


    Integrated Tire Chain Protection Net
    Each fender comes equipped with a modular tire-chain protective net that safeguards against abrasion from docking equipment, floating debris, or accidental vessel contact. The net allows quick replacement of individual tires, reducing downtime and maintenance costs.


    Environmental and Operational Adaptability
    The rubber compound is formulated for resistance against ozone, UV radiation, saltwater, and extreme temperatures ranging from –40 °C to +70 °C. Additionally, optional smart pressure monitoring systems enable remote performance tracking, early detection of pressure loss, and proactive maintenance planning.


    Applications


    Large Container Terminal Operations
    Ideal for berthing high-frequency container vessels, pneumatic fenders provide high energy absorption and low hull stress, ensuring safe docking even during tidal variations or strong currents.


    Offshore Floating Storage and Production (FPSO) Units
    Suitable for dynamic offshore environments, the fenders maintain stability and cushioning for FPSOs and other floating platforms under wave action and variable loading.
