The prestigious PES (Power&Energy Solutions) magazine has published the article " Failure modes in offshore wind turbines: pitch systems" written by the DOCC-OFF partners HINE, XABET, SIRRIS and Basque Energy Cluster. The article highlights the importance of determining and understanding the failure rates of an offshore wind turbine in order to model and reduce operation and maintenance costs.
The relevance of the hydraulic pitch system in the reliability of the wind turbines, pushed DOCC-OFF project partners to design a data monitoring and analysis system to increase the probability of detection of the critical failure modes.
DOCC-OFF is an EU-funded project led by the Basque Energy Cluster (BEC), in which HINE, XABET, SIRRIS and Basque Energy Cluster are working to outline a condition monitoring strategy which may reduce the impact of some hydraulic pitch system failure modes on the wind turbine´s design load cases.
In that sense, the consortium will be devoted to identifying otherwise critical failure modes on the hydraulic pitch subsystem which may be made non-critical, or whose criticality may be reduced, via condition monitoring, and to develop a digital platform to capture and manage the operating data to detect and predict the identified failure modes in time.
The experiences and developments acquired in the monitoring of the failure modes in a specific subsystem can be applied to other critical subsystems of wind turbines, positioning DOCC-OFF as a best-practice that can be replicated and scaled up to other systems within the wind turbine.
