Introducing the Mooring System Anode

Innovative Mooring System Anode: A Breakthrough in Cathodic Protection

The maritime industry constantly seeks advanced solutions to enhance the longevity and reliability of mooring systems. Recognizing the challenges posed by electrochemical corrosion, KATRADIS S.A., in collaboration with the National Technical University of Athens (NTUA), has developed an innovative Mooring System Anode. This new anode design ensures effective corrosion protection, simplifies installation, and meets environmental sustainability standards.

Research & Development Process

The Mooring System Anode is the result of extensive scientific research and testing. The development process began at KATRADIS’ R&D division and was further refined through a two-year study with NTUA’s Metallurgy and Materials Science Laboratory.

Key objectives of the research included:

• Eliminating cadmium from the anode composition to reduce environmental impact.
• Enhancing electrochemical efficiency to ensure uniform corrosion protection.
• Simplifying installation for seamless integration into marina mooring blocks.

To achieve these goals, researchers conducted:

• Electrochemical performance tests in controlled laboratory environments.
• Material composition studies to identify optimal alloy combinations.

Field tests in marina settings to validate real-world effectiveness.

Breakthrough in Material Composition

Traditional anodes contain cadmium, a heavy metal that poses significant environmental risks. The Mooring System Anode utilizes high-purity aluminum (99.99%) or zinc alloys, completely eliminating cadmium without compromising performance. This innovation aligns with international environmental regulations, making it a sustainable choice for modern marinas.

Technical Validation & Performance Testing

To ensure the highest standards, the anode underwent comprehensive testing:

• Stereoscopic Imaging Analysis: Evaluated corrosion patterns to confirm uniform material dissolution.
• Electrochemical Potential Measurements: Verified consistent cathodic protection across various marine environments.
• Saltwater Corrosion Simulations: Tested under different salinity and temperature conditions to assess long-term durability.

The results demonstrated superior protection capabilities, with minimal degradation over extended periods, proving its effectiveness in real-world applications.

Installation Innovation

One of the key advantages of this system is its ease of installation:

1. The anode fits into pre-drilled mooring concrete blocks, eliminating the need for specialized equipment.
2. Integrated cables allow for direct connection to mooring chains, creating an immediate corrosion protection system.
3. The system ensures efficient electrical potential distribution, reducing localized corrosion risks.

Environmental & Operational Benefits

• Cadmium-Free & Eco-Friendly: Fully compliant with environmental standards.
• Reduced Maintenance Costs: Prolongs the life of mooring chains, lowering replacement frequency.
• Adaptability: Suitable for various marine applications, including ports, marinas, and offshore facilities.

Conclusion

The Mooring System Anode by Katradis S.A. represents a significant leap forward in cathodic protection technology. Through scientific research, material innovation, and practical field testing, this anode delivers exceptional performance while meeting environmental sustainability standards.

By collaborating with NTUA, KATRADIS continues to push the boundaries of maritime safety and sustainability, ensuring that marinas worldwide benefit from cutting-edge corrosion protection solutions.
