A probabilistic risk assessment framework for the impact assessment of extreme events on renewable power plant components
Sánchez Pozo, Nadia Nathaly; Vanem, Erik; Bloomfield, Hannah; Aizpurua Unanue, José Ignacio (Elsevier, 2025) -
Assessing heavy maintenance alternatives for floating offshore wind farms: Towing vs. onsite replacement strategies
Centeno-Telleria, Manu; Penalba, Markel (Elsevier, 2025)This paper presents the first comparative study evaluating towing and onsite replacement strategies for heavy maintenance of floating offshore wind (FOW) turbines. The towing maintenance strategy is characterised by a ... -
Blind Efficient Method for Optimizing Jiles-Atherton Model Parameters
Conde Garrido, Juan Manuel; Ugarte Valdivielso, Jone; Aizpurua Unanue, José Ignacio; Barrenetxea, Manex; Silveyra, Josefina María (IEEE, 2026)We introduce a novel blind optimization method for determining the parameters of the Jiles-Atherton model of hysteresis, eliminating the need for user-provided initial guesses or search spaces. A carefully designed ... -
An interpretable operational state classification framework for elevators through Convolutional Neural Networks
Olaizola Alberdi, Jon; Izagirre, Unai; Serradilla Casado, Oscar; Zugasti, Ekhi; Mendicute, Mikel; Aizpurua Unanue, José Ignacio (Wiley, 2025)Ensuring the safe, reliable, and cost-efficient operation of transportation systems such as elevators is critical for the maintenance of civil infrastructures. The ability to monitor the health state and classify different ... -
