What Are Foam Filled Fenders?
Foam filled fenders are cylindrical or rectangular marine fenders composed of three primary layers:
Polyurethane Outer Skin: The tough and abrasion-resistant outer layer is commonly made from a polyurethane elastomer, which resists damage from harsh marine environments.
Closed-Cell Foam Core: The core is made from lightweight, high-density, closed-cell foam that cannot absorb water. This core compresses pressurized, absorbing impact energy effectively.
Internal Steel Structure (Optional): Some heavy-duty fenders include an internal steel core or axis to guide towing and handling.
These fenders are available in various sizes and configurations to match different vessel types, starting from small boats to large tankers and naval ships.
Advantages of Foam Filled Fenders
Foam filled fenders offer several benefits over traditional fendering systems:
High Energy Absorption: The closed-cell foam compresses upon impact, dissipating energy efficiently and minimizing vessel damage.
Unsinkable: Even if punctured, the fender remains functional due to non-water-absorbent foam core.
Durability: Resistant to UV radiation, saltwater, oil, and chemicals, foam filled fenders are made to withstand tough environmental conditions.
Low Maintenance: Unlike pneumatic fenders, they don’t require inflation or constant pressure monitoring.
Customization: Available in different shapes, sizes, and colors to fulfill specific application needs.
Long Lifespan: With proper use, these fenders takes years with minimal degradation.
Common Applications
Foam filled fenders are used across a variety of marine environments:
Ship-to-Ship (STS) Transfers: Ideal for energy absorption during lateral berthing between large vessels.
Ship-to-Dock (STD) Berthing: Installed on piers or docks to protect both ships and infrastructure.
Naval Operations: Frequently used by navies this can reliability and performance under extreme conditions.
Offshore Platforms: Provide protection for supply vessels during offshore loading or unloading.
Types of Foam Filled Fenders
Cylindrical Fenders: Commonly used for larger vessels and ship-to-ship transfers.
Donut Fenders: Designed to float freely around a mooring post or pile, ideal for guiding vessels.
Square or Rectangular Fenders: Suitable for docks or quay walls requiring flat work surface contact.
Foam filled fenders certainly are a versatile and reliable solution for marine impact protection. Their rugged construction, high end, and low maintenance requirements make them a preferred selection for commercial, industrial, and military maritime applications. As ports and vessel sizes carry on growing, the interest in high-performance fendering systems like foam filled fenders will only increase, ensuring safer and more efficient marine operations.
