Book excerpt: Offshore wind energy is rapidly advancing as one of the cutting-edge renewable energy sources towards the global decarbonization goal. However, offshore wind energy is still twice as expensive as onshore wind. The Operational Expenses (OPEX) are responsible for a substantial portion. They constitute 25 to 30% of the total costs. Therefore, it is essential that market-leading operators like Ørsted redefine their maintenance strategies to make the sustainable technology more competitive. Digitalization has opened the doors to monitor the health state of the wind turbines and apply maintenance based on the risk to failure, but little investigation has been conducted to understand what is the actual impact of shifting to a condition-based maintenance strategy. This thesis develops a decision support tool for identifying the most cost-effective solutions for the medium to long-term maintenance planning of offshore wind farms. The model is based on time domain Monte Carlo simulations that analyze weather conditions, i.e., wind speed and wave height, models wind turbine failures and transportation systems such as Crew Transfer or Jack-up vessels, and schedules corrective, preventive and condition-based tasks. The model is tested on a hypothetical 80 wind turbine wind farm in the North Sea for a 10 years operation. The results show that Time-based Availability and Energy-based Availability increase more than 2% with a condition-based strategy. Production losses are reduced 10.72%.
