Structural composition
Foam fender usually consists of the following parts:
Inner core:
Adopt closed-cell polyethylene or other high-density foam materials with excellent resilience and compression resistance.
Reinforcement layer:
Usually, a reinforcement layer made of high-strength synthetic fiber or nylon is used to enhance the strength and tensile properties of the fender.
Outer coating:
The outer layer is usually a polyurethane material or a wear-resistant rubber coating with good impact, corrosion, and UV resistance.
Features
1. High resilience:
The internal foam material effectively absorbs energy and quickly restores its shape, reducing damage to ships and docks.
2. Low maintenance cost:
The outer layer's wear and corrosion resistance enable it to be used long in harsh marine environments without frequent maintenance.
3. Good buoyancy:
Fenders can float on the water and adapt to tidal changes due to the lightweight properties of foam materials. Flexible installation: The lightweight design makes installation easy and suitable for different docks and ships.
The application of foam fender
Application scenarios Port terminals: Protect dock facilities and absorb the impact of berthed ships.
Offshore platforms: These are used for impact protection in offshore oil drilling platforms, wind power generation platforms, and other scenarios.
Ship protection prevents direct collisions between ships during berthing, operation, or towing.
Temporary protection: Provide temporary protection in special operations such as floating docks, rescue ships, and other scenarios.
Advantages comparison
Compared with other types of fenders (such as rubber and airbags), foam fenders have the following advantages: No failure due to puncture and higher safety. Adapt to various environments, terrible weather, and complex sea areas. Long life and can maintain high-performance stability.
Precautions
The appropriate fender size and specifications should be selected according to the operating environment. Regularly check the integrity of the outer coating to avoid performance degradation caused by long-term wear. Avoid contact with sharp objects to extend the life of the fender.
Conclusion
Foam fenders have become an indispensable and essential facility in modern port and marine operations due to their efficient energy absorption and protection performance.
