Digitalisierung und Verarbeitung von Sensordaten für die Zustandsbewertung von Oberflächenschutzsystemen stählerner Türme von Onshore‐Windenergieanlagen.

Digitalization and the use of sensor data for the condition monitoring of surface protection systems of steel towers of onshore wind power structures The paper describes the concept of a fully data‐based, mainly automated, procedure for the condition monitoring of surface protection systems on steel structures. Acquisition, processing and evaluation of relevant data as well as their implementation into a mathematical‐empirical condition monitoring model are discussed. The monitoring model is based on the definition and assessment of a local deterioration degree, which is characteristic for pre‐defined reference areas at the structure. The creation of the reference areas by means of In‐situ Virtual Twin Computation is introduced. The data‐based assessment procedure is practically exemplified on a steel tower of an onshore wind power structure in a rural corrosive environment. The procedure can be applied to steel structures with similar geometries (storage tanks, silos, chimneys) as well as to offshore conditions. [ABSTRACT FROM AUTHOR]
