    Description


    The Pneumatic Rubber Fender is a high-performance, air-filled fender system designed to absorb the kinetic energy generated during vessel-to-vessel or vessel-to-dock operations. Constructed with a robust rubber outer layer and multiple layers of synthetic-tire-cord reinforcement, it delivers exceptional elasticity, durability, and pressure stability.


    During berthing, the fender’s internal air pressure provides a uniform, controllable reaction force. This property makes it particularly effective for protecting both hull and dock structures from impact damage. Pneumatic fenders are widely adopted in international ports, naval bases, shipyards, and offshore terminals where flexibility, portability, and reliability are critical.


    Case Study – LNG Terminal in Qatar


    In 2023, Hongruntong Marine supplied 36 sets of 3.3 m × 6.5 m 50 kPa pneumatic rubber fenders to an LNG export terminal in Qatar. The customer required a fendering solution that could withstand continuous STS (ship-to-ship) transfer of large LNG carriers under high wave conditions. Each fender was tested according to ISO 17357-1:2014 and pre-inflated to a working pressure of 50 kPa.


    During commissioning, the fenders demonstrated an energy-absorption efficiency exceeding 250 kN·m and a reaction force below 950 kN, outperforming the project’s design specification by 8 %. After one year of operation, inspection showed no pressure loss greater than 3 % and no surface cracking, confirming the long-term stability of the Hongruntong design. The client subsequently standardized this model for all LNG berths, citing easy deployment and low maintenance as key benefits.

    Features


    Advanced Reinforced Structure
    Each fender is built using multi-layered synthetic-tire-cord fabric arranged in a cross-ply pattern. This reinforcement technology allows uniform stress distribution and exceptional resistance to internal pressure fatigue.


    High Energy Absorption / Low Reaction Force Ratio
    Through optimized geometry and controlled internal pressure, the Hongruntong fender achieves one of the best EA/RF ratios in the industry. This ensures gentle contact with the hull while maximizing energy dissipation capacity.


    Enhanced Anti-Aging and UV Resistance
    Special-compound rubber formulations protect the outer layer from ozone, UV, and saltwater degradation. Even in tropical climates, service life can exceed 12 years without surface hardening.


    Smart Inflation and Monitoring System
    Optional integrated pressure sensors and Bluetooth data transmitters allow remote monitoring of inflation level and performance. This smart feature minimizes manual inspection frequency and improves safety management efficiency.


    Applications


    Ship to Ship Operations
    Ideal for oil, LNG, and bulk cargo transfers between vessels, where flexible spacing and constant contact pressure are vital for preventing hull deformation.


    Port and Jetty Berthing
    Widely used in commercial ports, fishing harbors, and container terminals to protect concrete quay walls and reduce maintenance of fixed structures.


    Offshore and Naval Platforms
    Provides safe cushioning for offshore floating structures, FPSOs, and naval support vessels under dynamic sea conditions.
