AWS Ocean Energy from Concept to Sea
Charles Taylor, Quoceant Director and co-founder, shares his experience of working to support AWS Ocean Energy on their Waveswing development programme.
I started working with our client, AWS Ocean Energy, in late 2016, at the start of their journey through the Wave Energy Scotland funded Novel Wave Energy Converter programme. Since then, I have been fortunate enough to be part of the engineering development process of the Waveswing across all stages; from feasibility and concept design to detailed design, build and demonstration. As a consultant, I often focus on one stage, or one detail of a project so getting to be part of the full project cycle from drawing board to demonstration always brings added satisfaction.
AWS Ocean’s Waveswing is a 16kW prototype, weighing 50 tonnes, and is 7m tall and 4m in diameter. It is a submerged spar buoy which works by reacting to changes in the pressure caused as waves pass by. This iteration of the design is focused on remote power applications such as subsea oil fields and oceanographic monitoring equipment.
Our involvement in the AWS project spanned a variety of specialties including input into power take-off systems, environmental control, structural hull design and analysis, and the O&M planning and availability analysis. Quoceant worked with AWS Ocean Energy and their other sub-contractors to approach the design in a risk managed way, following DNV codes and standards. Design assumptions were where possible confirmed by Finite Element Analysis or OrcaFlex simulations (both of which we can do in house) and AWS carried out a series of tank tests which we supported.
The prototype device was built and commissioned in Malin Marine’s fabrication yard in Glasgow in 2021. It was then transported to Orkney where it began testing at the European Marine Energy Centre (EMEC) in April 2022.
