Irish National Doctoral Research Cohort on Floating Offshore Wind Dynamic Cables is formed

Sustainable Energy Authority Funded Project FlowDyn RDD/966 on Floating Offshore Wind Dynamic Cables brings together the largest group of researchers around this topic in Ireland and the first national doctoral research cohort.  This timely project addresses robust and niche training around the current and future needs in renewable energy, with a focus on offshore wind and collaborates extensively with academic and industry within and outside Ireland in a strategic manner, to deliver maximum impact.

The project is overall led by Vikram Pakrashi, University College Dublin and comprises of University College Dublin (UCD), Munster Technological University (MTU) and University College Cork (UCC). “FlowDyn allows us to demonstrate how fundamental ideas with rigour can be assimilated with industrial needs of the time in an interdisciplinary manner”, says Vikram, who is also the Director of UCD Centre for Mechanics and the lead of Offshore Wind strand of Science Foundation Ireland funded NexSys project.

“Dynamic Cables are one of the key elements that allows offshore wind power back to land. It is also one of the more vulnerable elements, leading to more frequent failures with large consequences around power generation and uncertainty around them. Overall, there is a strong need to better understand flexible cables in the marine environment in terms of materials, design and lifetime performance. ” adds Vesna Jaksic, research lead from Munster Technological University.

“Addressing the challenges of dynamic cables is difficult due to the fundamental complexity of these cables not just in terms of their modelling but also in terms of lack of evidence in testing and monitoring in controlled and natural environments.  We should try and close this gap between fundamental insights in this area and having adequate tools at hand to eventually absorb them into industrial practice.”, says Jimmy Murphy, the research lead from University College Cork.

FlowDyn approaches these challenges by creating a doctoral cohort of six researchers to understand complex static and dynamic responses of these cables over their lifetime exposure conditions, failures, monitoring, design, control and other challenges. The idea is to concurrently create fundamental insights, authoritative numerical/experimental tools and benchmarks while demonstrating best practices for industrial adaptation, as well as for doctoral research.

“FlowDyn is privileged to have some of the best researchers in Ireland to address this topic at various stages of their career. This includes Kevin Nolan (UCD) in experimental fluid dynamics, Mert Celikin (UCD) in experimental material science, Abdollah Malekjafarian (UCD) in monitoring, Aasifa Rounak (UCD) in fundamental nonlinear dynamics, Philip Cardiff (UCD) and Alojz Ivankovic (UCD) in computational mechanics for solids/fluids, Jennifer Keenahan (UCD) in computational fluid dynamics modelling, Rui Teixeira (UCD) in probabilistic engineering mechanics, Jimmy Murphy (UCC) in wave basin testing and offshore engineering, and Vesna Jaksic (MTU) in structural engineering and design of offshore and composites. I think it will be an amazing experience for the new researchers working with this team and with each other., concludes Vikram Pakrashi.
