PhD CASE Studentship with Ryder Geotechnical: Assessing the impact of scour on the capacity of foundations for floating offshore wind turbines
Number of awards
Start date and duration
September 2020 for four years
Scour can have a significant effect on the capacity of offshore foundations¸ reducing the available holding power¸ and risking failure. Scour is typically assessed by making an allowance for a scour pit around the pile during the design process¸ or by carrying out ground improvement measures post or prior to installation. These options are considered reasonably conservative¸ and the latter can have environmental effects. Within the oil and gas industry where a single large structure is installed with a small number of mooring piles¸ the consequence of conservatism is considered negligible; however¸ when considering floating wind farm arrays¸ which will use a significant number of piles¸ the consequence of scour will be significant.
This study aims to assess the effects of scour using 3D finite element analysis with advanced soil constitutive models¸ able to capture the combined effects of scour and cyclic loading. Scour effects on design loads will be quantified through pile rotation accumulated with increasing numbers of load cycles and cumulative pore-water pressure over time as plastic strain develops.

The award is available to UK/EU applicants only. Depending on how you meet the EPSRC’s eligibility criteria, you may be entitled to a full or a partial award.
It is anticipated that the successful applicant will have a first degree at 2:1 or 1st class (or equivalent relevant experience) in civil engineering¸ science or related discipline. A relevant Master’s degree and/or employment experience is an advantage. Experience in numerical modelling in geotechnical engineering and in particular with the use of advanced constitutive models would also be desirable. A minimum IELTS score of 6.5 or equivalent.
