Abstract
Functional corrosion protection systems are absolutely essential for ensuring the durability of offshore wind energy converters. As an alternative to conventional corrosion protection systems, a thin layer of high performance mortar could be applied around the turbine tower to protect it from the harsh maritime conditions. A flowable mortar with a high density is required in order to prevent a chloride penetration that could potentially damage the steel structure. In this context, the Institute of Building Materials Science in Hanover applied special test specimens under real maritime conditions on an existing wind energy converter in the North Sea. The test specimens represent the mineral corrosion protection system and were exposed for about five years to the maritime conditions. Since the aggressiveness of offshore conditions varies with the position along the wind energy converter, the test specimens were applied in three different altitudes (atmospheric zone, splash zone and underwater zone). This paper presents an innovative concept for a mineral corrosion protection layer for offshore applications. Different mortar systems were investigated with regard to their penetration resistance against chlorides and their corrosion protective capacity in general. The offshore exposure was accompanied by additional laboratory investigations.
