Multi-scale Laboratory and Numerical Investigation of Offshore Pile Foundations under Operational and Extreme Loading


   Department of Civil Engineering

  ,  Wednesday, January 04, 2023  Competition Funded PhD Project (European/UK Students Only)

About the Project

Offshore wind energy plays a key role in advancing UK’s Net Zero CO2 roadmap and tackling global energy crisis. Foundation system supporting or anchoring wind turbines are evolving to meet the critical needs for harnessing wind energy in deeper waters, difficult grounds, and seismic areas. This PhD project aims at optimising the design of offshore pile foundations under operational and extreme (storm, earthquake) loading by employing a multi-scale experimental and numerical approach to: (i) investigate how sands and transitional soils respond to monotonic, cyclic and dynamic loading considering variable loading rates and partial drainage conditions through laboratory testing; (ii) further develop available soil models to capture non-uniform cyclic loading behaviour and enable coupled hydro-mechanical 3D FE simulation; (iii) understand soil-structure interaction mechanisms under complex loading scenarios through benchmarking large-scale pile tests in heavily instrumented grounds.

The project capitalises on the supervision team’s expertise in advanced laboratory/field testing and numerical modelling. The successful applicant will benefit by working in close collaboration with vibrant research projects at the newly established UKCRIC Soil-Foundation-Structure Interaction (SoFSI) Laboratory and other ongoing projects such as the ESPRC-SFI ROBOCONE project that develops a new site investigation tool for offshore geotechnics. The University of Bristol further offers development schemes that train competent PhD candidates to undertake hourly-paid graduate teacher roles and pursue Higher Education Academy Fellowships.

Candidate Requirements

The candidate must have a first class, or a strong upper second class, honours degree in civil, mechanical, or relevant subjects, as well as excellent written and spoken communication skills. Recent graduates and those with relevant industry experience are welcome. Please note, acceptance will also depend on evidence of readiness to pursue a research degree.

Scholarship Details

Candidates are recommended to apply for the CAME EPSRC Doctoral Training Partnership (DTP) Scholarship. The selection process is competition-based across the School and this project is granted priority.

The DTP scholarship is open to UK students and EU applicants who have been resident in the UK for at least 3 years and have UK settlement or pre-settlement status under the EU Settlement Scheme. The scholarship covers tuition fees at home rate, tax free stipend (£16,062 pa for 2022/23) and travel/consumables budget of in total £4,900 for 3.5 years. The successful candidate is expected to enrol before 31st March 2023.

For eligibility and residence requirements please check the UKRI UK Research and Innovation website.
