Predicting foundation response for offshore wind turbines Supervised by Britta Bienen, Conleth O’Loughlin
The aim of this research is to predict the installation and in service response of suction buckets supporting offshore wind turbines. This foundation concept is now being adopted in offshore wind farm designs. Following self-weight penetration into the seabed, the bucket is installed by pumping water out of the bucket, which creates a pressure differential across the lid and drives further penetration. In service, the foundation needs to resist the cyclic loading imposed on the turbine from the ocean environment. The mechanisms of suction installation (in layered soils in particular) and the effects of the installation process on the soil state are poorly understood. The evolution of foundation stiffness and displacement underpin the design. The research will be predominantly experimental, utilising recently developed purposedesigned experimental facilities. The project is a collaboration with Lloyd’s Register EMA and Melbourne University.

In support of the research programme related to the safe disposal of nuclear waste, KU Leuven, SCK•CEN and PSI are looking for a PhD candidate for following topic:
Diffusion of gases in desaturated clay-based materials
The main aim of the PhD is to investigate how desaturation influences the diffusive properties of the samples for gases. This will be accomplished by performing diffusion experiments on different clay-rich materials (e.g. Boom Clay, Opalinus Clay, bentonite, sand-bentonite mixtures, …) at different degrees of saturation (but still highly saturated to avoid a continuous gas pathway), using different gases (He, Ne, CH4, C2H6). Different methods to perform transport experiments under desaturated conditions exist (e.g. osmosis method, saturated salt method …), but none of them has been used to measure diffusivity of dissolved gases. Diffusivity data will be complemented with a full petrophysical characterisation of all samples in order to assess the effect of changing petrophysical properties on diffusivity, and to compare the observations to those of fully saturated samples. The PhD will be executed in the international context of the EC-EURAD project, with close collaboration between SCK-CEN and the Paul Scherrer Institute (PSI, CH) and other partners involved in EURAD.
