Port Fenders Long Service Life Lightweight Construction Easy Installation
Description
The Floating Foam Fender is a high-performance marine fender specifically designed for extreme climate and offshore engineering applications. Constructed from high-density closed-cell polyethylene foam encased in a marine-grade polyurethane or synthetic rubber skin, the fender delivers superior energy absorption, exceptional durability, and consistent buoyancy, even in harsh weather, freezing conditions, or intense UV environments.
Engineered to withstand heavy berthing impacts and continuous wave and tidal forces, the fender maintains low reaction force to protect both vessels and structures. Its unsinkable design eliminates the risk of failure in critical offshore or extreme environmental operations. The outer coating provides UV, abrasion, and corrosion resistance, ensuring long-term performance and minimal maintenance.
Available in diameters ranging from 1,000 mm to 4,500 mm and lengths up to 5 m, the fender accommodates vessels from small service boats to 60,000 DWT cargo and offshore vessels. Its floating and adaptable design allows it to operate efficiently across tidal ranges, rough seas, and extreme weather, making it ideal for offshore platforms, wind farms, and exposed port facilities. By reducing vessel impact and structural damage, the fender significantly enhances operational safety and lowers overall maintenance costs.
Case Study – Offshore Wind Farm Berth
At a North Atlantic offshore wind farm, the installation of Floating Foam Fenders protected service and supply vessels ranging from 2,000 to 10,000 DWT. Previously, vessels experienced hull scratches and platform mooring wear during berthing in high waves and strong winds.
The installation of fenders with 1,500 mm diameter and 3 m length improved docking safety, reduced maintenance of both vessels and platform mooring points, and maintained consistent performance under sub-zero temperatures, strong UV exposure, and continuous saltwater spray. Feedback from operators confirmed that the fenders provided reliable protection and operational efficiency, making them suitable for replication across other offshore service berths.

Features
Extreme Climate Resistance
The foam core and outer coating are engineered to endure temperatures from -40°C to +80°C, UV exposure, ice, and heavy rainfall without losing structural integrity or energy absorption performance.
High Impact Absorption and Low Reaction Force
The high-density foam core uniformly dissipates impact energy, reducing peak stress on hulls and offshore structures. This enables safe berthing for heavy offshore vessels and equipment transport ships without excessive force on mooring points.
Long Term Durability and Corrosion Resistance
The polyurethane outer layer provides excellent resistance to saltwater corrosion, marine growth, and chemical exposure, ensuring a service life of 15–20 years even under extreme marine conditions.
Floating and Adaptive Design
The fender automatically adjusts to water level fluctuations and wave motion, maintaining continuous protective coverage, which is critical for offshore platforms, exposed ports, and floating pontoons.
