High Impact Absorption Pneumatic Rubber Fender Low Reaction Force Long Service Life
Pneumatic Rubber Fender is a marine engineering protective system designed for vessel berthing and ship-to-ship contact operations. Constructed with reinforced rubber layers combined with high-tensile synthetic cord fabrics and internally pressurized air structure, it forms a flexible energy-absorbing body capable of maintaining controlled deformation under external impact loads.
Case Study
Structural protection system implementation was conducted for a deep water container terminal in Northern Europe operating vessels up to 120,000 DWT under high frequency berthing cycles and strong tidal variation conditions. The terminal previously experienced accelerated fatigue stress accumulation on quay wall structures and increased maintenance frequency.
Hongruntong Marine supplied Pneumatic Rubber Fender systems with reinforced cord layer configuration and optimized pressure retention structure. After deployment, impact force measurements showed significant reduction in peak loading, structural vibration levels were lowered, and berthing stability improved under variable tidal and weather conditions.
