Product Overview
Pneumatic Rubber Fender is a large-scale marine impact energy absorption system engineered for deep water port infrastructure and ultra large vessel berthing operations. Constructed with multi-layer reinforced elastomer structure integrated with high tensile synthetic cord reinforcement and a sealed pneumatic chamber filled with compressed air, enabling controlled deformation behavior under extreme impact loading conditions.
The operational principle is based on high volume pneumatic compression mechanics, where kinetic energy generated during vessel berthing is converted into controlled internal air pressure displacement and structural membrane deformation, allowing gradual dissipation of impact energy while maintaining low reaction force transmission to both vessel hull structures and quay wall systems.
Case Study
A deep water container terminal in Northern China designed for handling ultra large container vessels up to 220,000 DWT encountered significant structural load concentration issues on berth face structures during high energy berthing operations.
Hongruntong Marine supplied Pneumatic Rubber Fender systems with enhanced volume design, high pressure stability control, and reinforced multi layer cord structure optimized for ultra large vessel impact conditions. After system deployment, the terminal recorded significant reduction in peak structural load transmission, improved vessel berthing stability, and enhanced structural fatigue resistance performance.
