_____________

Substructures of offshore wind turbines have to reliably withstand environmental conditions, operational and extreme loads during their design lifetime that may exceed the time period of 25 years. Within their lifetime, they may experience damage and structural changes. This study proposes a novel, data-driven approach for the quantification of probability of detection (POD) for the structural change due to scour on a monopile substructure. To achieve this aim, numerical analyses with finite elements are combined with real measured vibration data from an offshore wind farm.

Probabilistic Approach for Detection of Scour on Monopile Substructures Using Measured Structural Health Monitoring Data
