About this project
The UK is committed to the use of offshore wind energy to reach net-zero carbon emissions by 2050. The EPSRC-NERC Aura Centre for Doctoral Training (CDT) in Offshore Wind Energy and the Environment will enable delivery of this target by developing environmental and engineering solutions to key offshore wind sector challenges; thereby supporting a sustainable energy supply. In partnership with Offshore Renewable Energy Catapult (ORE Catapult), a 4-year taught and research industry-sponsored Aura CDT PhD is offered. The PhD directly addresses sector needs to understand power cable sensor design.
Failure and repair of array and export cables represent one of the largest costs for wind farm operators and are a focus for extensive research interest. There are varied root causes for cable failures, including stresses caused by seabed movement and free spans, overheating as a result of excess burial depth and excessive curvature during installation and burial, but these are poorly understood.
Fibre optic sensing schemes are an attractive solution for through-life distributed measurement of temperature and strain, making use of the existing optical fibres embedded in the cables for communication purposes. However, there are limitations on the spatial resolution and the resolution of temperature, strain and curvature that can be achieved. This PhD will consider a range of fibre optic sensing schemes and associated interrogation techniques to assess their capabilities in measuring temperature, strain and curvature when incorporated into different cable cross section structures.
A particular focus will be on improving spatial resolution and resolving strain/curvature in 2 dimensions; which is important for understanding cable loading but is not currently possible. The research will develop a sensing approach, possibly combining distributed or discrete sensing schemes, to address the aforementioned issues. Research project activities will include modelling, design and fabrication of prototype sensors or sensing schemes and the cable structures needed to achieve the aims of the project. These potential solutions will be evaluated experimentally.
The post is available from September 2020 as a full-time position. You will join Cohort 2 of the Aura CDT in Hull, in the heart of the UK’s Energy Estuary – the global centre for research, innovation and development for the sector. Initially, you will study for a Postgraduate Diploma in Offshore Wind Energy and the Environment, followed by a 3-year PhD supported by ORE Catapult.
