Operation and Maintenance of Floating Offshore Wind Turbines

Abstract

This chapter starts by shortly addressing the statistics of accidents and component failures of wind turbine structures based on a comprehensive dataset publicly available. The distribution of the types of offshore wind turbine structures installed in European waters is given. The operation and maintenance of fixed structures foundations is discussed. Then, the failure data of main subassemblies of wind turbines are presented and discussed, followed by a description of available and important condition monitoring systems, techniques and methods for operation and maintenance of wind turbines. Finally, the knowledge on modelling, simulation and optimization of operation and maintenance actions of fixed offshore wind turbines is discussed as a basis for the application in the operation and maintenance of floating offshore wind turbines.
