The WILLOW project has released new insights into its work on monitoring pitting corrosion, a highly localised form of corrosion that poses a significant challenge for offshore wind structures. This effort brings together the expertise of CEIT, Sirris, and C‑Cube International, who are jointly investigating how pitting develops and how it can be more accurately assessed under real marine conditions.
Pitting corrosion is particularly relevant for offshore wind foundations, where exposure to changing environmental conditions can lead to substantial variations in corrosion behaviour. As part of WILLOW’s activities, Sirris deployed corrosion coupons on the Blue Accelerator – Maritime Innovation and Development Platform (POM West‑Vlaanderen). Early observations indicate that the position of each coupon on the monopile strongly influences pitting intensity, offering valuable insights into how environmental exposure shapes corrosion risk.
The consortium is combining experimental testing, field monitoring and advanced analytical methods to deepen understanding of pitting mechanisms and support improved risk assessment approaches within the project. Initial findings are already promising, and further results are expected as the monitoring campaign progresses.
