Condition monitoring of offshore wind turbines

In this chapter, vulnerable offshore wind turbine components, which could lead to long downtimes, are discussed based on the reliability data observed. As the failures of these components can potentially lead to long downtimes and significant revenue loss in the offshore environment, their operation and health condition should be properly monitored. In this chapter, the significance of monitoring these vulnerable components is further emphasized through discussing the consequent economic impacts of their failures. Following this, the relevant wind turbine condition monitoring techniques and commercially available wind turbine condition monitoring systems are discussed. Finally, the chapter ends with a summary of the existing challenges and issues as well as the future research tendencies in the field of offshore wind turbine condition monitoring.
