Abstract

Guidance on corrosion protection is currently being provided in DNV GL Guideline for the Certification of Offshore Wind Turbines, Edition 2012, DNV-OS-J101, or DNV-RP-B401. This guidance is updated and summarized in the upcoming DNV GL Recommended Practice on Corrosion Protection of Offshore Wind Farms. Our world wide experience leads to relevant information on cathodic protection systems design for typical foundation structures of wind farms, on the inside and outside of monopiles and jacket types. Recommendation will be given on choice of coating systems, corrosion allowance, the necessity of pre-qualification, and the effects of durability of these. Also the danger of microbiologically induced corrosion or the effects of high (tidal) currents will be presented. Guidance and justifications for the recommended approaches will be given.
