Foam-filled fenders enhance the operational efficiency of wharves in the following ways:

  1. Efficient energy absorption to reduce equipment wear and tear

Foam-filled fenders utilize lightweight, highly elastic closed-cell foam materials (such as polyurethane or expanded EVA) internally. Through compression deformation, they efficiently absorb the impact energy from vessels, alleviating the stress on wharf structures and reducing the likelihood of damage to both fenders and wharves. This significantly lowers maintenance frequency. For instance, they maintain structural stability even when compressed by 60%, with energy absorption efficiency far surpassing that of traditional pneumatic fenders, thereby substantially extending equipment service life.

2. Maintenance-free design minimizes downtime

The external protective layer, made of polyurea or polyurethane, provides properties such as corrosion resistance, penetration resistance, and acid-alkali resistance. This enables a service life of 10-15 years, during which frequent inspections or replacements are unnecessary, reducing operational interruptions caused by maintenance.

  3. Flexible installation for complex environments

These fenders employ chain suspension or flange mounting methods and possess buoyancy, allowing them to operate unaffected by tidal ranges. They can be rapidly deployed in various wharf areas with different water depths, meeting diverse operational scenarios and enhancing wharf scheduling flexibility.

  4. Cost and environmental advantages

The materials are eco-friendly and offer low overall costs. Similar to new materials like foam concrete (which also demonstrates low cost and energy efficiency when used in revetments), long-term use of foam-filled fenders can save on repair and replacement expenses, supporting efficient and sustainable wharf operations.
