In view of the significance of fatigue reliability in wind turbine structural integrity, reliable probabilistic fatigue theories are necessary for design scheme optimization.

Among typical failure modes of wind turbines, fatigue is a common and critical source. Consequently, the core concerns for wind turbine manufacturers and operators are to increase its reliability and decrease costs, therefore enhancing commercial competitiveness. However, wind power is only one of the options, together with other renewable energy sources. Wind, as a sustainable and affordable energy source, represents a strong alternative to traditional energy sources. We employ a case study and sustainable reuse scenario for a site in the vicinity of Porto, Portugal. The framework proposed identifies an optimized reuse plan that incorporates metocean data analysis, structural analysis, life-cycle evaluation, and revenue optimization. We outline a study that employs a fatigue reliability-based framework to aid in such sustainable reuse planning and optimization. To maximize the benefits of such reuse of assets, what is needed is a rational optimization strategy that considers the remaining life of a repurposed platform, associated retrofit and construction costs, and a future period of gross renewable energy generation following installation of the wind turbine. The potential for sustainable reuse of decommissioned offshore jacket platforms to support wind turbines is being considered as an attractive proposition in such a transition.

An offshore energy transition, even if only a gradual one, from carbon-emitting fossil fuel extraction to cleaner sources is recommended, if we are to slow the harmful impacts of climate change.
