Dock Mounted Fender Excellent Energy Absorption Corrosion Resistant Easy To Replace

Dock Mounted Fender Excellent Energy Absorption Corrosion Resistant Easy To Replace

Description

The D Type Fender from Hongruntong Marine is an advanced marine protection system designed for structures exposed to constant wave action, tidal changes, and vessel contact. It provides a reliable buffer between vessels and fixed installations such as bridge piers, floating docks, and offshore platforms, where both impact resistance and environmental durability are critical.

The fender’s distinctive D-shaped profile allows efficient energy absorption while maintaining structural stability. Its hollow core geometry balances elasticity and strength, offering consistent performance under compressive loads. Each fender is extruded from a specially engineered marine-grade rubber compound designed to resist ozone, UV, saltwater, and temperature fluctuations.

Case Study – Offshore Bridge Protection, Norway

A coastal bridge in western Norway faced frequent minor collisions from service boats and maintenance barges, especially during heavy tides and winter storms. The previous cylindrical fenders degraded rapidly, losing elasticity and tearing after two winters. Hongruntong Marine provided a customized cold-resistant D Type Fender using a low-temperature elastomer blend with enhanced tear resistance and anti-ozone additives.

Installed in 2020 along the pier faces, the D Type Fenders have since endured continuous exposure to freezing seawater, ice abrasion, and mechanical stress. After four years, inspection reports showed no structural damage, over 50% reduction in impact load on pier surfaces, and no performance loss even after temperatures below -25°C. The local marine authority recognized the system as a cost-effective, low-maintenance solution for coastal bridge protection.

This project demonstrated how Hongruntong’s D Type Fenders perform under extreme conditions—maintaining flexibility, adhesion, and shock absorption in harsh climates and corrosive marine environments.

Specifications

Features

High Energy Absorption and Low Reaction Force
The thick rubber body and hollow core design dissipate berthing energy efficiently while minimizing reaction stress on structures. Ideal for large-vessel docking where heavy impact loads are common.

Superior Fatigue and Compression Resistance
Formulated with carbon black reinforcement and advanced vulcanization technology, the fender maintains elasticity and shape even after years of continuous heavy-duty use.

Customizable Heavy-Duty Profiles and Mounting Options
Hongruntong Marine provides profiles up to D800, available in continuous extrusion or pre-cut modular sections. Mounting systems can be adapted for steel quays, concrete walls, or floating docks.

Extended Service Life and Cost Efficiency
The rubber compound resists oil, ozone, UV, and seawater, reducing material degradation and maintenance frequency. Long-term use minimizes total ownership costs and downtime.

Applications

Shipyards and Dry Docks
Provides continuous protection during vessel docking, repair, and launching operations, ensuring safe and stable hull alignment.

Industrial Cargo and Bulk Terminals
Protects quays handling tankers, heavy cargo, and container ships where repetitive high-energy impacts occur.

Heavy Offshore Construction Piers
Ensures safe berthing for heavy transport vessels, cranes, and support barges in offshore construction zones.

FAQ

1. How do D Type Fenders compare to pneumatic fenders in performance?
D Type Fenders require no inflation, offer stable performance, and need less maintenance over long-term use.

2. Can these fenders handle very large vessels or tankers?
Yes, our heavy-duty profiles (D500–D800) are designed for high-energy berthing and large displacement ships.

3. Is installation complex for industrial quays?
No, the flat-back design allows easy bolting or welding onto existing steel or concrete structures with minimal modification.

4. What is the expected lifespan in heavy-duty use?
Typically 12–15 years depending on berthing frequency, environmental exposure, and maintenance practices.

5. Can Hongruntong provide technical drawings and loading calculations?
Absolutely, every project includes detailed drawings, mounting layouts, and impact load analysis for engineering approval.
