“…The wave energy is being investigated as an alternative to fossil fuels (Falcão, 2010;Ozkop and Altas, 2017). In this sense, a number of authors have focused on investigating the hydrodynamic performance of Wave Energy Converters through numerical models (Teixeira and Didier, 2021;Trivedi and Koley, 2021;Gang et al, 2022;Trivedi and Koley, 2023) and experimental approaches (Howe et al, 2020;Liu et al, 2022;Rodríguez et al, 2023). Notwithstanding, wave energy conversion technology is not competitive yet.…”

A computational tool is developed to investigate the trade-off between the energetic response and the structural integrity in Wave Energy Converters (WECs) for irregular waves. The computational model takes into account the environmental parameters and the properties of the WECs, and calculates the extracted wave power and the accumulated fatigue damage in a specific incident sea state. The hydrodynamic and the structural problems are solved using analytical and structural-finite element models, respectively. The methodology is exemplified for a specific bottom-fixed Oscillating Water Column with an optimal configuration and different energetic content sea states. The results reveal the importance of taking into account the trade-off between the extracted wave power and the accumulated fatigue damage to support decision-making in the predesign stage to provide better solutions for marine renewable energy applications. In the framework of the structure monitored using Internet-Of-Things, this computational tool can lead to a digital twin within the context of structural integrity.
