High Fatigue Resistance Cone Type Fender Lightweight And Structurally Strong

High Fatigue Resistance Cone Type Fender Lightweight And Structurally Strong

Description

The Cone Rubber Fender is a high-performance marine fender designed to provide optimal energy absorption and low reaction force during vessel berthing. Its unique conical geometry allows for high deflection, distributing impact energy efficiently while minimizing stress on both the quay wall and the vessel hull. This combination of geometry and robust construction ensures durability, reliability, and long-term performance in demanding port environments.

Manufactured from premium natural and synthetic rubber compounds, Cone Fenders incorporate multiple reinforcement layers, offering excellent mechanical strength, flexibility, and resistance to ozone, UV, and saltwater corrosion. The conical shape allows a large energy absorption capacity relative to its footprint, making it suitable for limited dock space while still accommodating large displacement vessels. Its modular design enables integration with steel backing plates or UHMW-PE facing panels, improving friction reduction and load distribution.

Case Study: Southeast Asia Bulk Cargo Port Expansion

A major bulk cargo terminal in Southeast Asia faced challenges with older cylindrical fenders that often failed under frequent berthings of Panamax and Capesize vessels. The terminal required a solution that could handle high impact energy, reduce quay wall stress, and withstand a high frequency of berthings without frequent maintenance.

Hongruntong Marine supplied Cone Rubber Fenders with reinforced steel backing plates and UHMW-PE facing panels. The installation was carried out with minimal disruption to port operations and included professional supervision and alignment verification.

After 12 months of continuous operation, monitoring showed a 40% reduction in peak reaction forces on the quay wall. Vessels reported smoother berthing, and maintenance inspections revealed minimal rubber wear and no structural deformation. The fenders maintained elasticity and performance under high tidal variation, proving their durability and efficiency. Port engineers acknowledged the system’s effectiveness in extending quay service life and improving operational safety.

Features

High Energy Absorption with Low Reaction Force
The cone-shaped geometry maximizes energy absorption while keeping the reaction force low. By distributing impact across the conical body, the fender reduces localized stress on both the quay wall and vessel hull. This design ensures safe berthing for vessels of various sizes, prevents hull scuffing, and minimizes dock maintenance costs. Its high energy-to-volume ratio makes it ideal for ports where space is limited but high energy absorption is required.

Durable Material Composition for Harsh Marine Environments
Cone Fenders are made from a proprietary blend of natural and synthetic rubber enhanced with anti-aging, ozone, UV, and saltwater-resistant additives. The material is optimized for tensile strength, elongation, and fatigue resistance. Reinforced layers within the fender body prevent deformation under repeated high-energy impacts. This ensures consistent performance over many years, even in extreme weather conditions and high salinity environments, significantly extending operational lifespan.

Corrosion Resistant Reinforcement and Stability
Internal reinforcements, combined with optional steel backing plates, provide structural stability under vertical and horizontal forces. Galvanized or stainless steel mounting options prevent corrosion and ensure secure attachment, even under dynamic load conditions such as tidal changes or angled berthings. The robust structure guarantees that the fender maintains shape and energy absorption characteristics throughout its service life.

Modular Design and Easy Maintenance
The modular construction allows rapid installation and replacement without specialized tools. Optional UHMW-PE facing pads reduce friction and protect hull coatings. Standardized bolt patterns simplify alignment on concrete or steel docks. The smooth surface design facilitates inspection and cleaning, while reduced maintenance requirements result in lower operational costs over the fender’s lifetime.

Applications

Bulk Cargo and Ore Terminals
Designed for berths handling Panamax and Capesize vessels, Cone Fenders protect quay walls and vessel hulls by efficiently absorbing high impact energy during berthing.

Oil, Gas, and Chemical Terminals
The fender’s high energy absorption and low reaction force are ideal for sensitive tankers, reducing structural stress and preventing cargo transfer interruptions during docking.

Naval and Offshore Support Facilities
Cone Fenders provide reliable protection for military and offshore vessels, supply ships, and tugboats, ensuring safe berthing and long-term operational efficiency.
