Maintenance and Operation of Cylindrical Rubber Fenders

This technical document focuses on the specifications, performance parameters, and maintenance guidelines for cylindrical rubber fenders used in maritime applications.

1. Specifications and Design Parameters

• The fenders are cylindrical rubber types designed to absorb energy during vessel berthing.
• Design deflection is specified at 50%, meaning the fender compresses to half its original thickness under load.
• Performance data provided is based on a standard fender length of 1000 mm.
• Key parameters include reaction force (R) and energy absorption (E), which are critical for ensuring vessel protection.
• The inside diameter (ID) of the fender is designed to be 50% of the outside diameter (OD), which influences performance characteristics.

2. Performance and Limitations

• Performance values and deflections are valid only for fenders with the specified ID to OD ratio.
• For deflections exceeding 50%, users are advised to consult the manufacturer or maritime contact for accurate performance data.

3. Maintenance and Operational Recommendations

• Regular inspection of fender condition is implied to ensure continued performance and safety.
• Proper installation and adherence to design parameters are essential to maintain energy absorption and reaction force capabilities.

4. Additional Notes

• The document includes graphical or tabular data illustrating the relationship between reaction force, energy absorption, and deflection, emphasizing the importance of maintaining design deflection limits.
• Profile fenders are mentioned, indicating possible variations or related products within the same category.

Critical Information: The fender's inside diameter must be 50% of the outside diameter for the provided performance data to be valid. Deflections beyond 50% require consultation with the manufacturer to avoid damage or failure.
