Corrosivity Control Inside Offshore Wind Power Turbines by Combined Dehumidification and Overpressure

Abstract

The contribution explores the significance of employing dry‐air technology as an efficient method for controlling and mitigating corrosion inside offshore wind turbine nacelles and towers. The article describes a dry‐air approach that curtails the necessity for costly corrosion protection measures and it explains its ability to diminish and regulate relative humidity. Additionally, it is outlined how the utilization of a dry‐air strategy results in the creation of an internal overpressure within the wind turbine structure. This overpressure effectively serves as a barrier against the ingress of moisture‐laden, salt‐infused air. Comparative site‐sensor data are presented and discussed for two dehumidification techniques. Finally, practical solutions are presented.
