Temporal evolution of stiffness for offshore monopile foundations

Onderzoeksoutput: Poster


Since 2011 OWI-lab has been conducting acceleration measurements on an offshore wind turbine with a monopile substructure at the Belwind wind farm. A site with layers of clay and sand. The main goal of the campaign was to validate the design with in-situ measurements on the operational turbine. Initial results confirmed that the actual resonance frequency was well above the as-designed values. Other researchers noted similar observations at different wind farms, concluding that in design the soil-stiffness was underestimated.
