Cylindrical Rubber Fender with High Energy Absorption Low Reaction Force and

Cylindrical Marine Fenders are one of the most widely used and cost-effective protective solutions in marine operations, designed to absorb impact energy and reduce reaction forces during vessel berthing, docking, and launching. With a simple yet robust cylindrical geometry, these fenders provide uniform load distribution along the contact surface, effectively minimizing localized stress on both vessel hulls and quay structures.

Manufactured from high-performance natural rubber or synthetic elastomer compounds, cylindrical fenders are engineered to deliver excellent elasticity, high tensile strength, and long-term durability. Standard diameters typically range from 150 mm to 2000 mm, with lengths customizable to suit specific operational requirements.

These fenders exhibit outstanding resistance to abrasion, UV radiation, ozone, and seawater corrosion, ensuring stable performance in harsh marine environments. Their high energy absorption capacity combined with low reaction force makes them particularly suitable for handling vessels of various sizes, from small service boats to large cargo ships.

A commercial port in Vietnam handling 40,000-60,000 DWT bulk carriers experienced frequent issues with excessive berthing impact forces, especially during monsoon seasons with strong currents and crosswinds. The existing fender system showed rapid wear and insufficient energy absorption, leading to increased maintenance costs and safety concerns.

Hongruntong Marine provided customized cylindrical fenders with a diameter of 900 mm and reinforced wall thickness, specifically designed to handle higher energy loads. The fenders were installed vertically along the quay wall using chain suspension systems, allowing controlled movement and better energy dissipation during vessel contact.

After implementation, the port recorded a significant improvement in berthing safety. Impact forces were effectively reduced, minimizing stress on both the vessels and quay structures. Berthing operations became smoother and more efficient, reducing docking time by approximately 12%.

Additionally, the durability of the fenders resulted in lower maintenance frequency and cost savings over time. The client expressed strong satisfaction with the performance and reliability of the solution, and similar configurations were later adopted in adjacent berths.
