“…As given in (2), the WT extracted power 𝑃 𝑤 is related to 𝑃 𝑘 through the power coefficient 𝐶 𝑝 , which is defined by ( 3)-( 4) and is related to the blade pitch angle 𝛽 and the tip-speed ratio 𝜆. The tip-speed ratio is given in (5), where 𝑙 [m] is the blade length and 𝜔 𝑤 [rad/s] is the turbine angular speed. The WT torque is given with the expression in (6) [28], [29].…”

“…Typically, 80% of the cost of offshore O&M is attributable to accessibility during inspection and the requirement to transport engineers to remote sites for asset inspection to evaluate a problem and decide on the remedial action to undertake [9]. Advancements in fault detection methods utilizing advanced sensing technologies, data analysis and modelling, has reduced the need for logistically expensive and time-consuming human interventions, which require specific transport windows due to weather conditions [10], [11].…”

“…Advancements in fault detection methods utilizing advanced sensing technologies, data analysis and modelling, has reduced the need for logistically expensive and time-consuming human interventions, which require specific transport windows due to weather conditions [10], [11]. This has resulted in operators achieving a reduction of 17% per MW in O&M, which maximizes the potential and minimizes the associated costs of offshore wind energy generation [9], [12], [13].…”

“…As wind increases its share in the overall generation, its reliability becomes more important for reasons such as power system stability and cost-effect of failures [1]. Additionally, reliability is an important driver of the Levelized Cost of Electricity (LCoE) for power generation assets [2], [3].…”

“…A crucial sub-assembly in this category is the power converter. The high rate of occurrence of failures is a bigger issue for WTs comprising offshore wind farms where the access for intervention is more expensive and difficult, thus increasing the resulting downtime [2].…”
