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.
On 29 April from 2:00 to 3:30 pm (CEST), a webinar will present key results of the project. 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.
Provisional programme:
- Introduction of the context of the project
- Nature of GACP releases
- Environmental aluminium concentrations from in-situ measures and modelling
- Ecotoxicology results on aluminium and chemical risk analysis
- Presentation of initial ICCP results
- Point of view from an offshore wind farm developer
- Conclusion and perspectives
