Floating Foam Fender High Energy Absorption Excellent Impact Resistance Unsinkable Structure
Description
The Floating Foam Fender is a high-performance marine protection solution designed for demanding port, shipyard, and offshore environments. It combines a closed-cell polyethylene foam core with a reinforced elastomer or polyurethane outer skin, providing reliable energy absorption, structural resilience, and long-term durability without the risk of air leakage.
The fender is engineered to deliver stable performance under repeated high loads. Its foam core offers consistent reaction force and energy absorption even after prolonged compression, while the outer protective layer ensures excellent resistance to abrasion, seawater, UV radiation, and harsh weather conditions. Unlike pneumatic fenders, the floating foam fender requires no inflation or pressure monitoring, significantly reducing operational risks and maintenance costs.
Available in a wide range of diameters and lengths, the Floating Foam Fender can be customized to match specific vessel sizes, berthing energies, and installation conditions. Optional fittings such as chains, flanges, or mounting brackets allow flexible integration into quay walls, dolphins, or floating structures.
From a functional perspective, the product is designed to protect both vessels and port infrastructure by minimizing berthing impact forces, reducing structural stress, and improving overall docking safety. Its unsinkable design ensures continuous protection even in the event of outer skin damage, making it a dependable solution for critical marine operations.
Case Study – Container Terminal Berthing Upgrade
A Southeast Asian container terminal handling 30,000–50,000 DWT container vessels experienced frequent quay damage due to outdated rubber fenders. Floating Foam Fenders with a diameter of 2.5 m were installed along the berth line.
After installation, vessel berthing impact was reduced by over 40%, maintenance downtime dropped significantly, and operators reported smoother docking even under tidal variations. The solution has since been replicated across three additional berths following positive feedback from terminal operators.

Features
High Energy Absorption Capacity
The foam core distributes impact energy uniformly, reducing peak stress on vessel hulls and quay walls. This design enables safe berthing for large displacement vessels without excessive reaction force.
Abrasion and UV Resistant Outer Skin
The reinforced elastomeric coating resists abrasion from repeated vessel contact and maintains structural integrity under prolonged UV exposure, ensuring long service life in tropical and offshore environments.
Unsinkable and Maintenance-Free Design
Even if the outer skin is damaged, the closed-cell foam prevents water ingress, eliminating sinking risk and minimizing maintenance requirements compared to inflatable systems.
Stable Performance Under Tidal Conditions
The floating design allows the fender to automatically adjust to water level changes, maintaining effective protection across varying tidal ranges.
