Abstract

The offshore wind industry increasingly considers vibro-driving as an alternative to traditional impacthammeringfor monopile installation. However, uncertainties persist regarding the post-installation performance of vibro-driven piles. This study addresses these challenges by: (i) Developing a minivibro-driver for a geotechnical centrifuge; (ii) Analysing vibro-installation response in sandy soils; (iii)Evaluating lateral loading response of vibro-driven and impact-hammered tests. Results show the importance of different vibro-driving and soil parameters during installation, particularly the dynamic/static force ratio. On lateral loading, a higher number of vibro-driving cycles correlates with improved response. This research enhances understanding of vibro-driving, aiding optimisation of offshore wind turbine foundations
