In the present study, a three-dimensional coupled numerical model is developed to investigate the excess pore pressure development around a monopile foundation and the accompanying changes in the effective stress of the seabed soil. In addition to the coupled hydrodynamic-geotechnical analyses, physical model tests have been performed at the Coastal & Ocean Basin (COB) in Ostend (BE), to better characterise the seabed response around on a monopile foundation based on pore pressure measurements. The experimental setup and the first results will be presented at the conference.
