Position on Turbine Reliability Risk Assessment: Proven and Qualified Turbine Designs and Turbine Availability in North America
Technical Memo, document: 104776-AM-01, date: 5 January 2011
In its role as leading consulting engineer for wind energy projects worldwide, DNV GL has had the opportunity over the years to closely observe evolving trends in wind farm performance. DNV GL uses this vantage point to develop and refine methods of assessing wind turbine reliability, quantifying risk, and projecting future performance.
This memo will also outline DNV GL’s updated methods for projecting turbine availability levels and assessing the design of a turbine model as “commercially proven” or “qualified”.
