Liquefaction Around Marine Structures: Development of a Numerical Modelling Framework in OpenFOAM®

Wave-induced liquefaction results in significant seabed dynamics and can lead to a complete loss of the bearing capacity of the soil. With the increasing use of marine space for energy harnessing, geotechnical challenges move into focus during the development and planning of such installations. To date, a lack of comprehensive modelling tools for wave-induced liquefaction around marine structures has been observed. This paper documents the efforts in the framework of the NuLI-MAS project to provide such a modelling tool. In particular, this paper presents a numerical implementation of the hydro-geotechnical processes together with a detailed overview of the calibration and validation strategy employing small-and large-scale experimental data, respectively.
