Dock Bumper Strong Impact Resistance Long Lifespan Low Maintenance UV Protection
Description
The V-type Dock Rubber Fender is engineered to deliver superior protection for berthing vessels while safeguarding dock structures from impact damage. Constructed from high-quality elastomeric rubber, it combines resilience with long-lasting durability to withstand extreme maritime conditions such as strong waves, salt corrosion, and prolonged sun exposure. Its V-shaped design provides optimal deflection and energy dispersion during docking, minimizing the risk of hull deformation and structural damage.
Case Study
At the Port of Singapore, the V-type fender was installed along a busy oil tanker berth. After one year of service, operators observed a marked reduction in minor hull scratches and structural impacts, even during high tide and strong currents. The fender effectively absorbed kinetic energy from tankers exceeding 50,000 DWT, confirming its capability in high-stress environments.

Features
Enhanced Energy Dissipation
The V-type fender’s unique shape allows it to distribute berthing forces evenly across the contact surface. Testing under simulated berthing conditions shows that it can reduce the impact force by up to 45% compared to traditional rectangular fenders, ensuring both vessel safety and dock longevity.
Premium Rubber Composition
Hongruntong Marine’s rubber blend features superior elasticity and wear resistance. The material resists saltwater, UV exposure, and harsh temperatures, guaranteeing consistent performance over time. Laboratory testing confirms that the material maintains over 85% of its original elasticity after 7 years of continuous outdoor exposure.
Versatile Installation
The V-type fender can be installed on vertical or horizontal surfaces and is compatible with both new constructions and retrofit projects. Its modular design simplifies replacement and reduces downtime. Maintenance is straightforward, requiring only periodic inspections and cleaning.
Sustainable and Cost-Effective
The fender’s long lifespan minimizes replacement frequency, lowering overall maintenance costs. The environmentally friendly rubber meets international marine standards and does not release harmful substances into the water, supporting sustainable port operations.
Applications
Oil and Chemical Terminals
V-type fenders protect both vessels and piers from high-impact berthing while resisting chemical corrosion, making them ideal for oil and chemical ports.
Bulk Cargo Ports
These fenders are suitable for berthing bulk carriers, efficiently absorbing impacts from vessels loaded with heavy materials like coal, ore, or grains.
Ferry and Passenger Terminals
Repeated docking of ferries and passenger vessels can cause wear on docks. The V-type fender reduces impact stress, ensures passenger safety, and maintains dock integrity even during high-traffic periods.
