Top 5 Things to Consider Before Buying Rubber Fenders
Date:2025-05-07
1. Berthing Energy and Impact Resistance
The most important factor in selecting rubber fenders is its ability to absorb the energy from the vessels that dock at your port. Ships come in various sizes and travel at different speeds, meaning their impact force can vary greatly.
So we should:
Calculate the berthing energy based on the size of the ships using the dock.
Consider fendersenergy absorption capacity. This ensures the fender can withstand the impact without degrading or damaging the port infrastructure.
Don’t just go by size—make sure the rubber compound is tailored to the expected impact.

2. Type of Rubber Fender: Choose the Right Shape
Rubber fenders come in different shapes and types—cylindrical, D-shaped, and more. Each type is designed to handle specific types of impact and provide optimal protection.
Consider the shape of the vessel and the docking conditions to choose the most appropriate fender.
3. Material Composition and Durability
The rubber compound plays a major role in determining how long the fender will last under harsh environmental conditions. It affects factors such as UV resistance, aging, and chemical resistance.
Choose marine-grade rubbermaterial that can withstand saltwater exposure, UV rays, and temperature fluctuations.
Ensure the rubbermaterial is abrasion-resistant, as the constant impact of ships can lead to wear and tear.
Choose compounds that include reinforced materials like carbon black for enhanced strength.
4. Mounting and Installation Flexibility
Rubber fenders need to be mounted securely to the port structure or dock. The installation process should be straightforward, and the mounting system should be flexible enough to handle varying conditions.
Consider the mounting style.
Ensure compatibility with your existing port infrastructure and consider factors like dock height, water depth, and wave action.
Think about the ease of maintenance and whether the mounting system allows for easy inspection and replacement.
5. Cost vs. Longevity and Maintenance
While it might be tempting to choose the cheapest option, a low-cost fender may wear out faster, costing more in repairs and replacements in the long run. Balancing cost with durability is crucial.
Consider the total life-cycle cost of the fender, which includes purchase, installation, maintenance, and replacement.
Higher-quality materials may have a higher upfront cost but provide longer service life and lower maintenance needs.
