Zusammenfassung: | Owing to the burgeoning offshore wind energy sector and ensuring its safe coexistence with existing maritime traffic, this study addresses the collision risks between ships and offshore wind farms. The maritime traffic routes around the Ulsan floating offshore wind farm project site off the coast of Korea, a region heavily reliant on maritime traffic, were analyzed. We devised a model to simulate the traffic distribution by considering various ship sizes and ship sizes. The collision probabilities between ships and wind farms were assessed along with ship-to-ship collision risks. The results showed that by designing the route width by considering the overall ship length below the 90% confidence interval, the probability of collisions can be considerably reduced. Because ship-to-ship collision probability significantly influences the overall collision probability, the maximum possible route width must be employed. The most appropriate route width according to the results of this study was 8943 m when considering future traffic volume increase based on a 90% confidence interval of the traffic distribution. The methods elucidated in this study can help stakeholders make decisions to set proper safety separation distance based on historical Automatic Identification System (AIS) data, to ensure safe ship and offshore wind farm operations.
