Arch Rubber Fender Uniform Force Distribution Low Maintenance High Compression Resilience
Description
Arch Rubber Fender is engineered to meet the demanding requirements of offshore facilities and heavy marine operations where vessels with high displacement and variable berthing conditions are involved. The distinctive arch-shaped structure allows the fender to absorb substantial berthing energy while maintaining controlled and predictable reaction forces, ensuring structural safety for both marine infrastructure and vessels.
The fender body is manufactured using premium-grade natural rubber compounds specifically developed for high load-bearing capacity and long-term fatigue resistance. These materials retain stable mechanical properties under continuous compression, large deformation, and harsh environmental exposure, including salt spray, ultraviolet radiation, and temperature variations commonly encountered in offshore environments.
Structurally, the arch profile enhances lateral stability and prevents buckling under eccentric loads, which are frequently encountered during offshore berthing where vessels approach at non-uniform angles. The fender can be supplied with reinforced steel frames, frontal panels, and low-friction UHMW-PE facing pads to accommodate large hull contact areas and reduce shear forces during vessel movement.
In offshore terminals, service bases, and heavy-duty marine facilities, Arch Rubber Fenders provide a reliable protective interface that minimizes operational risk, protects critical infrastructure, and supports safe and efficient marine operations. Their robust design and proven performance make them suitable for long-term deployment in challenging environments with minimal maintenance intervention.
Case Study
An offshore supply base supporting oil and gas exploration activities required a fender system capable of accommodating frequent berthing of offshore supply vessels (OSVs), anchor handling tug supply vessels (AHTS), and construction support vessels with displacement ranging from 15,000 to 35,000 DWT. The berth was exposed to open-sea conditions, with significant wind, current, and wave influence, resulting in variable approach angles and high localized berthing loads.
Hongruntong Marine supplied a heavy-duty Arch Rubber Fender system designed to handle elevated berthing energies while maintaining acceptable reaction forces for the existing quay structure. The fenders were configured with increased section thickness and optimized rubber hardness to ensure stable deformation under high impact loads. Installation was carried out along critical berthing zones where vessels frequently maneuvered under dynamic environmental forces.
Following implementation, the offshore base observed a marked improvement in berthing safety and operational reliability. The fenders demonstrated consistent performance under varying approach conditions, effectively absorbing impact energy and reducing lateral movement during vessel contact. After extended service in a corrosive offshore environment, the fender system showed no signs of premature material degradation or structural instability. Operational feedback confirmed improved confidence during berthing operations and reduced risk of structural damage, leading to the adoption of similar fender configurations for additional offshore berths within the facility.

Features
High Energy Absorption for Heavy Vessels
The Arch Rubber Fender is designed to absorb high levels of kinetic energy generated by large displacement vessels. Its structural geometry allows deep and controlled compression, ensuring effective impact mitigation even during high-energy berthing events.
Stable Performance under Eccentric and Angled Loads
Offshore berthing often involves non-uniform contact and eccentric loading. The arch-shaped profile enhances lateral stability and prevents unpredictable deformation, maintaining reliable performance under complex loading conditions.
Enhanced Material Resistance for Offshore Environments
The rubber compound is formulated to withstand prolonged exposure to saltwater, UV radiation, and temperature fluctuations. This ensures long-term durability and consistent mechanical properties in harsh offshore settings.
Compatibility with Heavy-Duty Fender Systems
Arch Rubber Fenders can be integrated with steel frontal frames, large-area facing panels, and low-friction pads, forming a complete heavy-duty fender system suitable for offshore and industrial marine facilities.
