Abstract
The offshore wind industry is developing quickly with an average yearly market development rate of nearly 7% in the next five years [4]. Services of wind turbines has ended up being costly and hard, in terms of safety, to be performed, especially the offshore ones. Denmark was the first nation to introduce a business offshore wind farms 30 years back and has been first mover in the wind business for a considerable length of time [2]. Standardization as a part of Danish Legislations are being established, these are to maintain a certain standard if UAVs produced and used in Denmark [6]. Danish legislation concern is on conducting risk assessment to apply for UAV exemption. The thesis in-hand does not include any type of quantitative data because of the lack access to same. Therefore, SORA was chosen to be a supporting risk assessment tool used since it can handle qualitative inputs. The purpose of this thesis was to identify and assess the operational risks in implementing UAV into supporting a maintenance crew in offshore wind turbine. A case study on Rødsand II was conducted where an application for UAV operator is proposed, using SORA, to identify the risks. The result of the SORA analysis was found to be with medium robustness for the proposed threat and harm barriers according to the inputted criteria.
