Yokohama Pneumatic Fenders are engineered marine energy absorption systems designed for emergency berthing operations, rapid-response offshore logistics, and temporary maritime infrastructure deployment where conventional fixed fender installations are unavailable or impractical.
The system is constructed using a cylindrical elastomer pressure body reinforced with multiple layers of high-tensile synthetic tire-cord fabric, forming a sealed pneumatic chamber that operates under controlled compressed air pressure to dissipate kinetic berthing energy.
The operational principle is based on progressive pneumatic compression behavior, where internal air pressure increases in response to external impact forces generated during vessel contact under non-standard or emergency docking conditions.
Location: Typhoon Recovery Port, Philippines
Following a major typhoon event in the Philippines, a regional coastal port experienced severe structural damage to its primary berthing infrastructure, resulting in reduced operational capacity and inability to accommodate medium and large displacement cargo vessels required for humanitarian relief logistics.
Hongruntong Marine supplied a set of Yokohama Pneumatic Fenders configured for emergency deployment and temporary port reconstruction support. The system was rapidly installed along improvised berthing zones using available mooring structures and floating support platforms.
During operational deployment, the fenders demonstrated stable energy absorption performance under irregular vessel approach conditions and non-standard docking geometries, effectively mitigating impact forces during repeated cargo vessel arrivals delivering relief supplies.
