Postdoctoral Researcher in Environmental Research
University College Cork

Post-Doctoral Researcher, MaREI Centre, Environmental Research Institute


Position summary

Institute background

MaREI is a key research centre within UCC’s Environmental Research Institute (ERI) which is an internationally recognised Institute for environmental research dedicated to the understanding and protection of our natural environment and to developing innovative technologies, tools and services to facilitate a transformation to a zero carbon and resource efficient society. The MaREI Centre is an SFI-funded research centre headquartered in the ERI in UCC. The MaREI Centre includes 12 other Universities and Third Level Institutes, has 50 industrial partners and has research funding of approximately €55m. It combines the expertise of a wide range of research groups and industry partners, with the shared mission of solving the main scientific, technical and socio-economic challenges across the marine and renewable energy spaces. MaREI is also funded by SEAI, EI, EPA, ERDF, EU, HEA, Marine Institute, DCCAE and IRCSET IRC, as well as through contributions from our industry partners. Researchers in the MaREI Centre have over 30 years of experience in conducting fundamental and applied research supported by competitively won national and international funding, and commercial contracts with government agencies and industry. MaREI’s strengths lie in the multi-disciplinary nature of its research teams, allowing it to combine insights across areas such as MRE Technologies, Materials & Structures, Observations & Operations, Coastal & Marine Systems, Bioenergy, Energy Policy & Modelling, and Renewable Energy Management.

Project background

This project is a joint industry project between Supernode and UCC_MaREI. The SuperNode concept is centred on providing a single superconductor connection to offshore renewable energy sources. Existing land based superconducting cables are not fit for purpose for offshore deployments. Super conducting cables require extreme cooling to operate HVDC efficiently. The primary issue is that over the length of pipes heat ingress reduces performance of the superconducting material. To operate under deep sea high pressure conditions a new type of conduit will have to be developed. This project aims to characterise these superconducting conduit concepts into physical prototype designs and test them to determine if they are potentially suitable for deep sea operation. This will be achieved through a range of numerical modelling and physical testing activities. The proposed conduit concepts to be examined are based on a superconducting material cooled by circulating Liquid nitrogen (LN2) through a Pipe in Pipe system that includes a vacuum sealed annulus. This conduit concept is known as a “Cryostat”.
During the project it is planned to develop a set of numerical models of various Cryostats. The modelling will include analysing thermal and structural performance. The performance of the cryostats will be characterised for both insitu operational and installation/mobilisation cases.

Role description

MaREI wishes to recruit a Post-Doctoral Researcher with experience in FEA and CFD numerical modelling of pipe and subsea related activities. The successful candidates’ role will include:

  • CFD Thermal Performance Model development of Cryostat
  • Liaison with engineering team and Supernode on model requirements
  • Undertaking validation and operation of CFD modelling activities.
  • Designing generic cases for testing as well as pilot case studies to examine various specimens for thermal performance assessment
  • Completion of weekly progress reporting
  • Production of Interim and Final modelling reports to acceptable standard as laid out by PI
  • Contribute to publication process during project including drafting and editing manuscripts
  • The candidate should have significant and demonstrable research experience in CFD and Thermal performance modelling. Cryogenic cooling and offshore cable/pipeline modelling an advantage. An understanding of the key challenges developing subsea superconductor cryostats, particularly thermal issues. Knowledge of appropriate modelling packages and approaches to undertake CFD thermal modelling of the required nature. Competency in Matlab and Ansys Fluent and Workbench or similar.
