Postdoc Numerical Modelling of Cyclically Loaded Monopile Foundations for Offshore Wind Turbine

Updated: 3 months ago
Deadline: 09 Jan 2024

We invite applications for a Postdoctoral position within the Offshore Engineering Group at TU Delft's Civil Engineering faculty. In this role, the successful candidate will contribute to advancing our understanding of the cyclic behaviour of offshore foundations both under environmental (wind-wave) and seismic loading conditions.

The selected applicant will explore and advance our understanding of cyclic soil-monopile interaction, working with state-of-the-art experimental data (geocentrifuge) and numerical modelling. Within this domain, there are scientific challenges in comprehending the fundamental nature of cyclic behaviour in both cohesive and cohesionless soils. Equally intriguing is the translation of this understanding into practical engineering models.

The role will involve the meticulous development, set-up, and calibration of 3D Finite Element monopile models, coupled with the implementation of constitutive models. The candidate will be immersed in projects with strong industrial support.

As a post-doctoral researcher, you will:

  • Lead research on cyclic soil-monopile interaction in offshore wind turbines using state-of-the-art numerical modeling.
  • Tackle fundamental challenges in understanding and conceptualizing cyclic behaviour of monopiles in cohesive and cohesionless soils. Translate this understanding into engineering models, including cyclic soil reaction modeling.
  • Explore the cyclic behaviour of laterally loaded monopiles in cohesionless, cohesive soils, and soil mixtures under various loading conditions (wind, wave, and seismic).
  • Develop, set up, and calibrate 3D Finite Element (FE) models. Implement constitutive models and finite elements for simulating geotechnical problems of offshore monopiles.
  • Contribute to projects involving experimental elements, including participation in centrifuge testing. Numerically reproduce and expand upon experimental results.
  • Collaborate on research projects, pushing the boundaries of offshore foundation design. Projects include MIDASclay (cyclic behaviour of laterally loaded monopiles in cohesive soils), DONISIS (seismic modelling of monopile-supported wind turbines in liquefiable soils), and GeoWin (tool development for soil investigation and offshore foundation design).
  • Engage with industrial partners, demonstrating excellent communication skills. Deliver project reports.

Candidates shall meet as many of the following requirements as possible:

  • PhD degree in Civil/Geotechnical Engineering or related areas;
  • High skills in 3D FE modelling and developing/using (open-source) FE software - such as, e.g., OpenSees. Experience in the implementation of constitutive models and finite elements is a big plus;
  • Proven experience in finite element analysis and constitutive modelling, especially regarding soil-structure interaction problems and cyclic loading conditions;
  • Excellent knowledge of soil mechanics (including dynamics) and foundation engineering. Acquaintance with offshore wind geotechnics is also appreciated (but not mandatory);
  • Experience in implementing and calibrating constitutive models preferably in the framework of bounding surface plasticity;
  • Interest in contributing to the global success of research projects, liaising with other team members responsible for different segments of the research;
  • Appreciation of team work, good social skills, and ability to function in international circles involving experts from academia and industry;
  • High proficiency in spoken/written English, and proven experience in preparing technical publications and project reports;
  • Interest in contributing to educational activities, including occasional teaching, student tutoring and co-supervision of BSc/MSc graduation projects.

Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities. The duration of the contract is 3 years with a possibility of extension. The TU Delft offers a customisable compensation package, discounts on health insurance, and a monthly work costs contribution. Flexible work schedules can be arranged.
