Design of warranty extension model for wind turbine blades

Mature industries like Automotive, Electronics and Industrial equipment already have proven concepts of extended warranty offerings. However, Energy/Renewables being a maturing industry, warranty extension offering is still in its nascent stages. As the industry is becoming more and more competitive, it is expected that extended warranty may become a norm to protect customers' high capital investments. This paper explores application of various life data analysis techniques to calculate warranty extension risk at a granular level like for a particular failure mode or a specific customer based on historical trends. By doing this, the management is being provided with some fair understanding of the risk that arises out of extended warranty.
