Decommissioning of Offshore Wind Farms
After a useful life of 20 to 25 years of existing offshore wind farms, the decommissioning will be a challenging task. In this context, an optimized planning of decommissioning enables savings of energy costs. Due to the lack of sufficient empirical data about decommissioning of offshore wind farms, simulation techniques represent a suitable analysis tool to investigate such planning problems. The present contribution examines the effects of tactical decisions in the decommission phase of offshore wind farms by the use of a discrete-event, agent-based simulation study. The variation in the number of used vessels as tactical decision in connection with weather conditions is investigated. The results show that adapting the number of vessels can reduce about 6% of the decommissioning duration.
