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 chloride penetration that could potentially damage the steel structure. However, such mortars have a relatively high tendency to shrink, which might lead to the formation of cracks in the mineral layer. These cracks increase the possibility for the ingress of water and chlorides penetrating through the mortar, thereby raising the risk of corrosion. To reduce these cracks respectively, the maximum crack width and to ensure an adequate layer thickness, the high-performance mortar (HPM) has to be applied by using textile reinforcement and suitable formwork. This paper presents concepts for a possible realization of a textile reinforced mineral corrosion protection system for offshore wind energy converters (OWEC). To this end, different textile reinforcements were investigated with regard to their suitability for application and crack width limiting properties by using a model steel tower.
