When producing increasingly larger fibre composite turbine blades the wind power industry is facing major challenges of consistent quality and sufficient robustness.
A major concern in the wind power industry is the long time it takes to establish internationally recognised standards. DNV has therefore launched a Joint Industry Project (JIP) to develop a Recommended Practice for defects and damage in composite structures and components.
The Recommended Practice will contain a catalogue of production defect types and observed in-service damage.
