Working for a major windfarm operator, we undertook a review of internal corrosion issues it was experiencing on some of its monopiles.
This included reviewing previous studies and measurements of internal cathodic protection (CP) usage, leak rates, pH, gas generation, microbiologically influenced corrosion (MIC), etc.
Having determined the relevant mechanisms in the different monopiles, we were able to review the proposed retrofit options the company was considering, and the potential side effects of each option. This included the development of a ventilation system for hydrogen and hydrogen sulphide from the internal air space below the airtight deck.
A key aspect of this project was linking in our structural team to provide advice on the client’s primary concern of remaining structural integrity.
