Methods and tools for the preactive maintenance of offshore wind turbine generators
The growing number of plants at sea, a varied demand for electricity and possible downtimes require an optimisation of the maintenance of offshore wind turbine generators (WTG) in the future. Especially unplanned downtimes lead to additional maintenance effort and thus to higher maintenance costs.
Duration of project:
04/2013 – 09/2016
Contract number of project:
The objective of the project is to research comprehensive methods and tools taking several data sources into account that can be used for a proactive maintenance strategy of the service of WTG. To enable an accurate prognosis about the condition of a component, a variety of data sources such as sensor values, statistic data, maintenance data from the maintenance history file, externalised staff know-how, weather data as well as stock inventory and personnel planning are analysed and automatically linked to a relevant event. The prioritisation of the detected errors, the dynamical planning of the scope of maintenance and the scheduling into the work flow with corresponding logistics using decentralised controlling systems are aspects of the project that are to be researched. These points of research should enable a proactive maintenance strategy for WTG.
Automated decision support
Offshore maintenance processes are recorded and data sources for an automated decision support are identified. Based on this, a basic concept will be developed and the required methods analysed or researched. This will enable an automated prioritisation of detected errors. The acquired knowledge will flow into the development of a software module. The developed methods and data are validated with real data as far as possible using a demonstrator which will be developed.
