A comparative study between the monitored and simulated response of a monopile located in the Belgian North Sea
This paper presents the results of a comparative study between the monitored and the simulated response of a monitored wind turbine monopile located in the Belgian North Sea, subjected to operational lateral loading. A 3D Finite Element model of the monopile is de-veloped in ABAQUS in which the soil is simulated using advanced constitutive models for sands and clays that are calibrated to advanced laboratory test data. It is found that using a stiffness profile that is calibrated from laboratory tests only induces the most mismatch when compared to the monitoring data. The effect of CPT-based correlations was also investigated, it was concluded that it was not the main reason behind the observed mismatch between the numerical models and the monitoring data.
