We are concerned with the question of which corrosivity categories for Fe-sheets can be found at an offshore wind turbine and where they are comparable with our offshore locations. The preliminary results indicate that the extreme corrosivity of class CX is only given in splash water-affected exposure, which is not a real atmospheric exposure condition. The results of the exposure at the SP show that the corrosivity category changes into C4, only a few meters above the splash water zone. Compared to the marine environments at Helgoland or OSS-Platform, the corrosivity is higher. The offshore environment is not as corrosive as originally expected, no atmospheric corrosion attack could be determined that would form the corrosivity category C5.
