We must innovate in the use of drones to service offshore wind farms cheaper, faster and more efficiently. The research project FOD4Wind between Energy Cluster Denmark, ESVAGT, Upteko, University of Southern Denmark (SDU) and Siemens Gamesa can reduce downtime and eliminate fixed costs for servicing offshore wind. Based on estimations of the project team, with 70 installed charging stations with drones, the annual effect in 2030 will be reduced downtime of 12,250 hours, 13,000 tons of CO2 reduction, increased energy production by 39,200 MWh, reduced costs for service by 57 million Euros and additional employment of 180 employees.
