    Accurately simulating atmospheric boundary layer flows is challenging because of their complex, multi-scale turbulence, limiting the reliability of wind predictions used in applications such as wind-energy planning and turbine design. CEEC used extreme-scale computing to perform high-resolution simulations with up to 100 billion grid points, providing more detailed atmospheric-flow information that could support improved wind-resource…

    Uncertainty in suction bucket installation can increase the risk of localized soil erosion and foundation failure, with potential consequences for installation time and offshore wind project costs. Using HPC-powered, grain-scale fluid–soil simulations, CEEC improved the accuracy of engineering models for predicting erosion and suction behaviour, helping reduce installation uncertainty and support more cost-efficient foundation installation.…

    Uncertainty in aeroelastic predictions forces aircraft manufacturers to rely on conservative design margins, increasing weight and certification costs. Using exascale fluid–structure simulations, CEEC demonstrated how high-fidelity modelling can improve load prediction, reduce development risk, and support more efficient aircraft designs.

    Suction bucket foundations offer significant advantages for offshore wind applications, enabling fast and cost-efficient installation. However, installation failures due to piping erosion remain a critical challenge, particularly in loose or highly permeable seabeds. Understanding the interplay between seepage flow, soil properties, and foundation geometry during suction installation is essential for improving design guidelines and installation…
