Marine Dock Bumper Corrosion Resistant High Impact Strength For Vessel Berthing
Marine Dock Bumper Corrosion Resistant High Impact Strength For Vessel Berthing
Product Overview
Cell Rubber Fender is a compression-type marine fender designed to absorb berthing energy and control reaction force between vessels and fixed marine structures. Its compact cylindrical geometry allows the rubber body to undergo controlled axial compression when a vessel approaches a quay wall, jetty, dolphin, berth face, or other supporting structure.
The main body is manufactured from specially formulated marine-grade rubber designed for high strength, durable performance, wear resistance, weather resistance, and repeated deformation. The rubber compound can be engineered according to the expected operating environment, including saltwater exposure, humidity, ultraviolet radiation, ozone, temperature variation, and frequent mechanical loading.
Case Study: Industrial Tanker Jetty in the Mediterranean
A representative industrial tanker terminal in the Mediterranean required replacement of aging berth protection equipment on a loading jetty used by medium-sized product tankers. The existing fender arrangement had experienced progressive rubber deterioration and wear on several contact surfaces, resulting in inconsistent vessel-to-berth contact conditions.
The Cell Rubber Fender arrangement was configured with reinforced rubber bodies, steel mounting components, and front contact panels incorporating UHMW-PE sliding surfaces. The rubber formulation was selected for long-term marine exposure, while exposed steel components were provided with appropriate corrosion protection for the salt-laden environment.

Key Features
Material Engineering for Stable Elastic Performance
The rubber compound is a critical component of Cell Rubber Fender performance because the material must repeatedly absorb mechanical energy without excessive permanent deformation. The rubber formulation provides a controlled balance between elasticity, hardness, tensile strength, tear resistance, and fatigue resistance.
Controlled Compression and Reliable Load Transfer
The cylindrical cell geometry is designed to provide controlled deformation when subjected to axial compression. As a vessel approaches the berth, the fender compresses progressively and generates a reaction force that counteracts the vessel movement.
Corrosion Protection and Durable Marine Accessories
Steel panels, chains, brackets, anchor bolts, washers, and other exposed components are protected against marine corrosion. Supporting steel components can be manufactured and protected according to project requirements with appropriate surface preparation and protective coating systems.
Precision Configuration for Long-Term Lifecycle Management
Cell Rubber Fender systems can be configured according to the dimensions and structural conditions of individual berths. This flexibility is particularly important during berth rehabilitation where existing anchor locations and structural dimensions may differ from newly designed installations.
Applications
- Industrial Tanker and Loading Jetties: Suitable for tanker berths where controlled reaction force and stable contact conditions are important
- Port Dolphins and Independent Berthing Structures: Compact and structurally coordinated fender systems for dolphins and similar marine structures
- Berth Rehabilitation and Replacement Projects: Customized configurations for existing ports and industrial marine facilities requiring fender replacement

Frequently Asked Questions
How is the required Cell Rubber Fender size determined?
The size should be selected according to vessel displacement, berthing velocity, berthing angle, available compression, required energy absorption, allowable reaction force, fender spacing, and supporting structure. Vessel size alone is not sufficient for final selection.
Can the Cell Rubber Fender be supplied with a front panel and UHMW-PE sliding face?
Yes. A complete system can be configured with a steel front panel and UHMW-PE sliding face where the project requires larger contact-area distribution or reduced friction during vessel movement.
How should steel components be protected against marine corrosion?
Steel flanges, panels, brackets, chains, and anchor components should receive corrosion protection suitable for the expected marine exposure. The coating or material specification can be selected according to seawater exposure, atmospheric conditions, and maintenance requirements.
What inspection is recommended after installation?
Inspection should verify rubber deformation, surface cracking or cuts, abnormal abrasion, front-panel alignment, UHMW-PE wear, anchor-bolt condition, chain and bracket condition, and corrosion of exposed steel components.
Can Hongruntong Marine provide project-specific testing and technical documentation?
Project-specific testing and documentation can be arranged according to the agreed technical specification and applicable project requirements. Documentation may include dimensional information, material data, inspection records, test results, drawings, and packing information.
