Cylindrical Marine Fenders are engineered to deliver high-performance impact protection in demanding marine environments, particularly where large vessels and high berthing forces are involved. Their robust cylindrical geometry enables efficient distribution of contact pressure while ensuring reliable energy absorption under extreme loading conditions.

Constructed from premium-grade natural rubber combined with reinforced synthetic elastomers, these fenders exhibit exceptional mechanical strength, high elasticity, and resistance to fatigue. Available in large diameters ranging from 500 mm to over 2000 mm, and with customizable lengths, they are suitable for heavy-duty applications such as bulk terminals, oil jetties, and industrial ports.

The design allows for progressive deformation during vessel contact, effectively reducing peak reaction forces while maintaining structural integrity. This characteristic is essential for protecting both high-value vessels and critical port infrastructure. Additionally, the fenders demonstrate superior resistance to abrasion, UV radiation, ozone exposure, and seawater corrosion, ensuring long-term durability even in harsh offshore conditions.

With flexible installation options and proven reliability, cylindrical marine fenders are widely used in high-impact berthing zones, shipyards, and offshore support operations. They provide a dependable solution for improving safety, reducing structural damage, and enhancing operational efficiency.

An iron ore export terminal in Western Australia required a high-capacity fendering system to accommodate Capesize bulk carriers exceeding 150,000 DWT. The primary challenge was managing extremely high berthing energy under strong tidal currents and heavy vessel displacement.

Hongruntong Marine supplied large-scale cylindrical fenders with a diameter of 1400 mm and reinforced internal structure to enhance load-bearing capacity. The fenders were installed vertically along the berth face, supported by heavy-duty chain systems designed to allow controlled movement during vessel impact.

Following installation, the terminal reported a substantial reduction in peak berthing forces. The fenders effectively absorbed impact energy, preventing structural stress on both the quay and vessel hulls. Operational safety improved significantly, particularly during adverse weather conditions.

The durability of the fenders also resulted in reduced maintenance interventions, contributing to lower long-term operational costs. The client confirmed that the solution met all performance expectations and has since standardized similar configurations for future terminal expansions.

• Exceptional Load Capacity for Heavy-Duty Applications: Cylindrical marine fenders designed for high-impact environments are capable of handling substantial berthing energies generated by large vessels such as Capesize bulk carriers and oil tankers. Their structure supports high compression loads while maintaining stability, ensuring reliable performance even under extreme operational conditions.
• Optimized Energy Absorption with Reduced Reaction Force: The fender's cylindrical form enables progressive compression, allowing energy to be absorbed efficiently over a longer deformation range. This reduces peak reaction forces transmitted to both the vessel and the quay structure, enhancing protection and improving safety during berthing operations.
• Reinforced Structural Integrity and Fatigue Resistance: Advanced rubber formulations combined with optimized wall thickness provide excellent resistance to fatigue caused by repeated loading cycles. The fenders maintain their mechanical properties over time, even under continuous heavy use, ensuring long-term reliability.
• Superior Environmental and Chemical Resistance: Designed for offshore and industrial environments, cylindrical fenders offer strong resistance to UV radiation, ozone, saltwater, and exposure to oils or chemicals. They maintain flexibility and strength across a wide temperature range, ensuring consistent performance in both tropical and harsh coastal climates.

• Heavy-Duty Bulk and Oil Terminals: Cylindrical fenders are widely used in terminals handling large vessels, where high berthing energy requires reliable impact absorption and structural protection.
• Shipyards Handling Large Vessel Construction: In shipyards building or servicing large ships, these fenders provide critical support during launching and docking operations, ensuring safety and stability.
• Offshore Mooring and Support Operations: They are also applied in offshore environments to protect vessels and structures during mooring and transfer operations, particularly under challenging sea conditions.
