| Abstract | Electricity production costs of offshore wind power plants are high compared to other energy sources. The costs of offshore wind power have to be reduced to be attractive as a renewable energy source. The operational costs, especially logistics costs, have a great potential for cost reduction. In this thesis a modular simulation model for the operation of offshore wind power plants is developed by using the software Enterprise Dynamics. The model is able to represent offshore-based and onshore-based logistics concepts. The output is logistics and opportunity costs (revenue losses). The model is used to gain new findings on the correlation between different influencing factors (e.g. weather conditions), parameters (e.g. number and type of equipment) and the logistics concept performance (economic viability). Based on the developments in the German North Sea, multiple simulation experiments have been conducted on three different logistics concepts (with four variants each) and nine offshore wind power plant scenarios. The validity of the results has been demonstrated through sensitivity analyses for selected input parameters. The investigation shows that for most German offshore wind power plants an onshore-based logistics concept is the most cost efficient option. An offshore-based concept only becomes the most cost efficient option for a large offshore wind power plant scenario with 90 wind turbine generators located 100 km away from the base station. The success of onshore-based concepts is related to the high additional equipment and personnel costs of offshore-based concepts. Other important findings are that no logistics concept is superior throughout the whole year, and that a combination of concepts leads to the best cost efficiency. The investigation also identifies that the influence of weather downtime (no mission possible because of bad weather conditions) on the availability of the offshore wind power plant is significantly higher compared to the downtime resulting from travel or repair works. The developed model distinguishes itself from other approaches by the event-discrete simulation character, transparent processes and the ability for monthly analysis. |
