NTNU PhD Scholarship Description :
- Three PhD Research Fellowship positions within foundation of offshore wind turbines The Faculty of Engineering Science and Technology at Norwegian University of Science and Technology ( NTNU ) invites applicants for three PhD Fellowships within Geotechnical Engineering Applied to Foundation of Offshore Wind Turbines.
- Research topics for the PhD Fellowships are to the following :
- PhD 1 : Numerical modelling of soil – wind turbine interaction an important design criterion for offshore wind turbines is to ensure that the eigenfrequencies are sufficiently far from the main excitation frequencies. The stiffness of the foundation gives an important contribution to the global stiffness and the eigenfrequency.
- The aim for this study will be to improve the calculation methods for stiffness and damping of the foundation – soil interaction. The study will include finite element modelling, development of constitutive models for practical Norwegian University of Science and Technology PhD Scholarship application to wind energy foundations and modelling of stiffness and damping applicable for fatigue life evaluations. Low strain stiffness of the soil will be addressed in particular the study may also include accumulation of plastic strains during cyclic loading.
- PhD 2: Revision of the p – y curves to improve their applicability to monopile foundations the p – y curves defined in current design standards ( API, DNV ) are based on field tests on more flexible and smaller diameter piles than the typical monopiles for wind turbine foundations. Applying the conventional p – y curves may result in over conservative foundation design.
- The main focus of this study will be to evaluate and improve the current p – y curves based on back calculation of instrumented full scale wind turbine foundations. The study may also include model tests on piles with length – diameter – stiffness ratios representative for typical monopile foundations. In addition the study may include the effect of scour on stiffness and capacity of wind turbine foundation.
- PhD 3 : Soil variability and Norwegian University of Science and Technology PhD Scholarships application of statistical methods the aim with this topic is to develop statistical methods to determine characteristic soil properties with a reliability level comparable to the other parts of the design and improve on the current costly over – design practice.
- The study may include soil data evaluation to identify soil properties and aspects of soil variability that affect the performance of offshore wind turbine foundations. The study may also involve developing probabilistic models that encompass important soil variability. The probabilistic models may further be integrated in to design methods using for instance the First Order Reliability Method or Monte – Carlo simulation.
