DNV GL has been chosen by Gamesa, to certify its wind turbine lifetime extension programme for the design of its G47 wind turbine, extending the lifetime to up to 30 years.
The turbine lifetime extension programme aims to maximise the profitability of ageing wind farms by reducing the lifecycle-based costs of energy of existing turbines and keeping them operational for a longer period of time. The life extension programme consists of a series of structural upgrades and monitoring features which allow owners to lengthen the useful lives of their turbines from 20 to 30 years of guaranteed safety and availability. The certificate awarded by DNV GL was based on detailed analysis of the design, specifications and applied calculations over the entire life of a Gamesa G47-660 kW wind turbine, from the year in which it is installed until year 30.
