This report contains the results of a cost-benefit analysis for the use of embedded sensors for damage detection in large wind turbine blades - structural health monitoring - (in connection with remote surveillance) of large wind turbine placed off-shore. The total operating costs of a three-bladed 2MW turbine placed offshore either without sensors or with sensors are compared. The price of a structural health monitoring system of a price of 100 000 DKK (per turbine) results in a break-even time of about 3 years. For a price of 300 000 DKK the break-even time is about 8 years. However, the cost/benefit analysis has large uncertainties.
