The objective of this project was to develop and establish a database for collecting reliability and reliability-related data, for assessing the reliability of wind turbine components and subsystems and wind turbines as a whole, as well as for assessing wind turbine availability while ranking the contributions at both the component and system levels. The project resulted in a software package combining a failure database with programs for predicting WTB availability and the reliability of all the components and systems, especially the safety system. The report consists of a description of the theoretical foundation of the reliability and availability analyses and of sections devoted to the development of the WTB reliability models as well as a description of the features of the database and software developed. The project comprises analysis of WTBs NM 600/44, 600/48, 750/44 and 750/48, all of which have similar safety systems.
