Abstract
    In this contribution the first results in the development of a SHM approach for the foundations of an offshore wind turbine will be presented. Key problems are the operational and environmental variability of the resonance frequencies of the turbine. This paper suggests a (non-)linear regression model to perform data normalization. Real-life data obtained from an offshore turbine on a monopile is used to validate the used model and to demonstrate the performance of the presented approach.
