Dock Fender Weather Resistant Corrosion Free Low Maintenance
Description
The Floating Foam Fender is a versatile, high-performance fender system designed for ports, shipyards, and dry dock operations. Constructed from a closed-cell polyethylene foam core encased in a reinforced polyurethane or synthetic rubber skin, the fender delivers superior energy absorption, structural resilience, and durability. Its unsinkable floating design ensures continuous protection of vessels during berthing, docking, and maintenance operations without the need for inflation or pressurization.
Available in a range of diameters from 800 mm to 3,500 mm and lengths from 1 m to 5 m, these fenders can accommodate ships ranging from small tugboats to 50,000 DWT bulk carriers. The outer skin’s abrasion resistance, UV stability, and marine corrosion protection make it suitable for long-term operation in tropical ports, industrial shipyards, and high-traffic berths.
The fender’s design allows it to adapt to tidal fluctuations, providing consistent hull protection and minimizing structural stress on quays, dry docks, and floating pontoons. By reducing the risk of hull damage and infrastructure wear, it enhances operational safety, lowers maintenance costs, and improves overall port efficiency.
Case Study – European Dry Dock Facility
At a European dry dock servicing bulk carriers and chemical tankers, frequent vessel docking caused structural wear on traditional rubber fenders and minor hull damage. Floating Foam Fenders were installed with diameters of 1,200 mm and lengths of 3 m along the dry dock walls.
Results: The fenders successfully absorbed repeated berthing impacts, protected both hull and dock infrastructure, and reduced dry dock turnaround time by 20%. Operators highlighted the fenders’ long-term durability, maintenance-free design, and smooth energy absorption, leading to adoption across multiple docks and berths.
