Descrizione
Despite significant advancements in offshore wind turbines (OWTs), effective life cycle assessment remains a critical challenge. An emerging limiting factor in the lifespan of these structures is vortex-induced vibrations (VIV), which may occur during the installation process, before the towers are commissioned in offshore wind farms. Over several weeks, VIV can cause substantial oscillation amplitudes, potentially leading to significant fatigue damage before the OWTs are fully operational. This issue is becoming increasingly crucial as OWTs grow in size and reduce in weight. In this context, the VIV-WISE project aims to develop and verify a new multi-physics numerical framework to address this issue. This tool seeks to (1) surpass the accuracy of current state-of-the-art by integrating novel fluid-structure interaction methodologies with recent advancements in damage mechanics, specifically the Phase Field model for fracture, to provide insights into fatigue damage caused by VIV in metals - particularly cylindrical shells and welds. (2) Establish a guide for identifying cracks induced by VIV in pioneering wind tunnel experiments, and (3) assist in the OWT tower installation process, thereby preventing significant failures before operation. Hence, VIV-WISE addresses a complex, multi-disciplinary phenomenon that encompasses both solid and fluid mechanics. The proposed methodology will not only be valid for OWTs, but also for other industrial sectors where VIV-induced fatigue damage is a concern, such as chimneys, marine risers and bridges.
