Practical wind turbine reliability

This chapter has demonstrated how WT reliability data can be used to benchmark WT performance for organising and planning future operations and maintenance, particularly offshore. Data need to be collected carefully and the taxonomy of WTs and wind farms must be defined in a common way, for which standards exist in other industries and are being prepared for the wind industry. It is also clear that the definition of failures, or indeed stoppages, need to be standardised to ensure that data can be compared in a useful engineering and management way.
