Durham University is one of the world's top universities with strengths across the Arts and Humanities, Sciences and Social Sciences. We are home to some of the most talented scholars and researchers from around the world who are tackling global issues and making a difference to people's lives.
The University sits in a beautiful historic city where it shares ownership of a UNESCO World Heritage Site with Durham Cathedral, the greatest Romanesque building in Western Europe. A collegiate University, Durham recruits outstanding students from across the world and offers an unmatched wider student experience.
Less than 3 hours north of London, and an hour and a half south of Edinburgh, County Durham is a region steeped in history and natural beauty. The Durham Dales, including the North Pennines Area of Outstanding Natural Beauty, are home to breathtaking scenery and attractions. Durham offers an excellent choice of city, suburban and rural residential locations. The University provides a range of benefits including pension and childcare benefits and the University’s Relocation Manager can assist with potential schooling requirements.
Durham University seeks to promote and maintain an inclusive and supportive environment for work and study that assists all members of our University community to reach their full potential. Diversity brings strength and we welcome applications from across the international, national and regional communities that we work with and serve.
The Department of Engineering is consistently one of the very best UK engineering departments with an outstanding reputation for excellence in teaching, research and employability of our students. We have a long history and tradition of Engineering. Engineering has been taught at Durham University since 1838 making it the first course of its kind in England. The Department provides outstanding course content that equips young engineers with the problem solving skills of the 21st century, is committed to an ethos of research-led teaching at all levels of its taught programmes, and is ranked 4th in the Complete University Guide 2022, 4th in the Guardian University Guide 2021 and 6th in The Times and The Sunday Times Good University Guide 2021 in the UK for General Engineering. Ranked 4th in the UK for Research impact at REF 2014, where 90% of the Engineering outputs were graded 3* or 4*, this dynamic department is an excellent place to work. We have helped to shape the past and continue to shape the future. The strategic vision for the Department includes a growth plan of over 50% over the next five years, with a significant enhancement of the research challenge portfolio, and a drive to enrich our undergraduate, postgraduate taught and postgraduate research provision. It is an exciting time to join this expanding Department and make your mark. The Department has an Athena SWAN Bronze Award, recognising our commitment to diversity in STEM academia and reflecting the supportive and positive environment within the Department.
Research in computational solid mechanics has been a strength of the Department of Engineering for many years, encompassing development of methods (such as finite elements, boundary elements, meshless methods, etc.) and their application to engineering problems. The Department also has a strategic focus on growing offshore geotechnics and renewable energy related research going forward, including the appointment of two new academic staff in 2021/22. Professors Coombs and Augarde lead an internationally recognised group of researchers developing the Material Point Method for problems involving large deformation, coupled non-linear material behaviour and contact, with a particular focus on problems relating to offshore geotechnics. If successful in your application you would be joining a growing group of researchers solving fundamental issues in the Material Point Method, building on the success of previously funded research and development.
Offshore Wind (OSW) is critical for the UK's economy and energy security. It is also an area of huge investment, for example £14bn has been committed up to the end of 2021 for new OSW sites - the 4th largest construction programme in the UK. Beyond this, the UK's current 2030 OSW installed capacity targets will require £48bn of investment and provide direct employment for 27,000 people. However, despite the growing maturity of the OSW sector, certain elements of the installed infrastructure remain problematic. Principally, problems associated with subsea power cables that transport and distribute the electricity generated offshore in wind turbine generators to the onshore transmission system currently account for 75% of the cost of all insurance claims and faults typically take 100+ days to rectify. This leads to breaks in supply and loss of revenue for the windfarm operator which in the long term can lead to longer pay back periods and reduced investment elsewhere in their renewables portfolio. In shallow waters these cables must be protected from anchors and fishing gear and the primary protection method is to bury the cable below the seabed.
The cable burial depth is a compromise between economic cost of burial (going deeper takes longer, requires larger ships and may require more complex operations) and risk to the cable being damaged by anchors/fishing gear penetrating the seabed. Within this context, anchor-cable interactions currently account for 85% of power cable failures. The planned rapid expansion of offshore wind around the UK - installed capacity increasing 7.5 times over the next 30 years - will require new cable installations within some of the busiest shipping/fishing waters in the world and it is essential that these new cables are installed at the appropriate depth. However, the industry currently lacks appropriate scientific tools to determine anchor penetration depths in different soil conditions. Instead, they use simple look-up tables based on very broad descriptive classifications of the soils on the seabed that basically split the huge spectrum of real soil conditions into two categories – soft or hard. This approach has been shown to be highly conservative in some soils leading to unnecessarily deep (and costly) burial. However, it is clearly non-conservative in other conditions (soft clay seabeds) as anchor-cable interactions dominate cable failures. This collaborative research project between Durham University, the University of Dundee and the British Geological Survey (BGS) will tackle the lack of sound anchor penetration models head on and, through physical testing and computational modelling, develop a toolkit to assess anchor penetration in different soil conditions
Applications are invited for a Postdoctoral Research Associate in Computational Solid Mechanics with a particular emphasis on large deformation modelling of soil-water-structure interaction problems using the Material Point Method. The EPSRC-funded research project (EP/W000970/1) is led by Professor Will Coombs in collaboration with Professor Charles Augarde in the Department of Engineering. The project aims to provide the fundamental scientific basis to allow engineers to estimate the likely penetration depth of drag anchors based on routine site investigation data. This will allow specification of appropriate cable burial depths in a variety of different soil conditions that balances risk to cable damage with installation cost.
The successful applicant will be expected to develop a Material Point Method-based digital design environment to assess the penetration potential of existing and new anchor designs across a spectrum of soil conditions, including layered soils. They will be expected to implement complex numerical algorithms within a high-performance computing environment as well as run parametric studies to understand the physical process. They will also be expected to collaborate with researchers from the University of Dundee and the BGS and interact with the industrial partners as well as disseminate the research findings via journal and conference publications. The successful applicant will report to Professor Willl Coombs and Professor Charles Augarde, including attendance at weekly project meetings. They will also be expected to engage in STEM outreach activities to promote the research project and inspire the next generation of engineers/scientists.
