This project aims to provide companies with an independent means to assess the corrosion risks in their installations, to increase their awareness and to have them take appropriate preventive actions. To this end, we created a simple, rapid, in situ sensor system able to monitor a range of environmental markers over time to determine the risk of corrosion of steel submerged in water, as well as a statistical method to mine these data for an overall corrosion risk estimate –in short, the SOCORRO system, set at TRL 4. In this project, we will implement and demonstrate this whole set-up in several industrial case studies (wind turbines at sea, water desalination/sanitation, ship’ hulls and ballast tanks, harbour sheet piles, process water) and show the economic opportunities. In addition, we will augment the statistical analysis with an intuitive, practical dashboard tool to present the outflow of information and to convey that risk to the end users. This will raise the TRL to 6 or 7.
