Simulation of microbiologically influenced corrosion in sediment/water interface in the monopile

Ensuring the safety of offshore wind structures (OWS) is critical to guaranteeing their long-term performance and supporting reliable green energy supply. Microbiologically influenced corrosion (MIC) presents a significant challenge, particularly for monopiles in seabed environments. This study investigates the behavior of microorganisms and their impact on the corrosion process of carbon steel within monopiles. To simulate MIC at the sediment/water interface, an in-house experimental column was developed and inoculated with sediment and water samples from the North Sea. The system was operated under varying flow rates to replicate seabed movement conditions. Multiple molecular
microbiological methods, surface analysis techniques, and other approaches were employed to assess the effects of different treatments. This study provides insights into MIC mechanisms in offshore environments and supports the development of strategies to monitor MIC in OWS infrastructure.
