Costs of repair of wind turbine blades: Influence of technology

An out-of-service turbine can cost $800–$1600 (USD) per day, with most repairs taking 1–3 days. If a crane is required to repair or replace a blade, the cost can run up to $350 000 per week. An average blade repair (offshore) can cost up to $30 000 (for onshore blades, it can be two times less) and a new blade costs, on average, about $200

Polymer Matrix Composites for Wind Turbine Blades

blades is that on the thickness of the composite the strength is ensured by the strength of the matrix. As presented in the literature, there are different sections and models of blade stiffening [16–20]. Some researchers [20] studied the problem of delamination of T-type joints between the cover and the stiffening elements inside the blade.
