Ecotoxicology of cathodic protections
Published on 16/04/2025
Cathodic protections – such as galvanic anodes (GACP) and impressed current (ICCP) – and anticorrosion paints are a widely used effective method to prevent the corrosion of metallic materials immersed in seawater. However, they lead to the chronic release of chemical elements into the marine environment, whose potential harmful effect is a concern for environmental authorities and civil society.
In this context, the recently completed ECOCAP R&D project worked on producing a knowledge base of the potential environmental impacts of anticorrosion protections commonly used in the offshore renewable energy industry
Final Webinar organised on 29 April
Key results of the project were presented during a webinar held on 29 April 2025. ECOCAP assessed the ecotoxicological risks of cathodic protections in marine environments by studying the chemical effects on various organisms and developing digital tools to simulate the dispersion and transfer of released elements.
