Marine Rubber Fender Heavy Duty Rubber Superior Shock Absorption Proven Reliability
Description
The V-type Dock Rubber Fender is designed to provide superior protection for berthing vessels while preserving dock infrastructure. Made from high-grade synthetic rubber, it offers excellent elasticity, wear resistance, and corrosion protection against harsh marine conditions. Its V-shaped geometry ensures effective impact energy distribution, reducing localized stress on both vessels and piers.
Case Study
At the Port of Hamburg, V-type fenders were installed along a cruise ship terminal. Within a year, terminal operators observed a significant decrease in minor hull scratches and dock wall damage, even under frequent docking of large cruise vessels exceeding 100,000 GT. The fender’s design provided reliable protection in high-traffic operations, ensuring safety and operational efficiency.

Features
Optimized Energy Absorption
The V-shape allows the fender to compress and dissipate energy evenly across the contact surface. Simulation tests indicate a 40–50% improvement in impact force reduction compared to traditional fenders.
Durable Rubber Material
Our premium synthetic rubber withstands abrasion, UV radiation, and saltwater corrosion. Lab tests confirm the material retains over 90% of elasticity after extended outdoor exposure.
Easy Installation and Maintenance
The modular design allows flexible vertical or horizontal installation. Sections can be replaced individually without dismantling the entire fender system, reducing downtime and maintenance costs.
Cost Effective and Eco-Friendly
Long lifespan reduces replacement frequency and operational costs. Environmentally safe rubber ensures compliance with marine ecological standards.
Applications
Cruise Terminals
Protects both vessels and pier structures from repeated berthing impacts.
Container Ports
Absorbs kinetic energy from heavy container ships, reducing stress on dock walls.
