Solution for longterm and sustainable corrosion protection for offshore wind farms

During this project, corrosion issues related to offshore wind farms were investigated, including the potential impact the current approach of mitigating these issues has on the marine environment.
Offshore wind farms

Offshore wind farms have a major problem with corrosion of the steel structures. The problem is that the corrosion mitigation methods tend to have a significant impact on the environment. The purpose of this research was to quantify the environmental impact of cathodic protection attached to offshore wind structures to prevent corrosion.



Different corrosion mitigation methods were evaluated, supported by a literature study. The study substantiated the expected negative impact of the traditional methods on the marine environment. It became clear that from the perspective of the environment, a fully effective coating system which would work without the need for additional cathodic protection would be preferable.
