An online platform for the management of digital visual data for the condition monitoring of protective coatings on marine steel structures The paper presents an online platform for the annotation and management of visual digital data, which allows for the condition monitoring and maintenance modelling of protective coatings of marine steel structures by means of digital image data only. A 10‐step procedure is introduced which includes the data acquisition, transfer of the data into the online platform, the annotation and management of the data by means of special tools and methods, and the modelling for condition monitoring and maintenance purposes. Some special applications of the platform are exemplary illustrated. [ABSTRACT FROM AUTHOR]

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]
