| Sumario: | ABSTRACT: Nowadays, wind energy is one of the most competitive and reliable renewable sources for power generation. The use of floating platforms, proved by few pilot systems, could open up vast potential markets and help offshore wind reaching a relevant role in the renewable energy mix worldwide. Operation, inspection and maintenance represent critical activities for a cost-effective implementation of offshore wind energy. This is mainly due to the difficulty of working at sea, far from the coast and in harsh weather conditions. This dissertation aims at reducing the risks and uncertainties associated to the long-term operation and maintenance (O&M) of floating wind farms. Four specific problems were studied: the relationship between operational stops and energy yield, the temporal and spatial variability of accessibility, the risk of walk-to-work transfer and the impact of failures on electricity generation. Several innovative methodologies were developed in order to quantify long-term energy production, accessibility and safety of personnel transfer at sea. This work highlights the importance of using long-term metocean data when designing O&M strategies for offshore wind. In addition, it offers suggestions for improving current access procedures and “walk-to-work” personnel transfer. Finally, it provides recommendations to optimize existing strategies and adjust them for future floating farms. |
