Turbulence in Marine Environments (TiME) reduces risk for tidal energy

Turbulent effects map

The TiME project consortium (consisting of partners Partrac, Ocean Array Systems, ABPmer, and IT Power). has announced today that the Guidance formulated from the TiME (Turbulence in Marine Environments) project has now been released. The project, funded by the Scottish Government and managed by the Carbon Trust through the Marine Renewables Commercialisation Fund (MRCF) Array Technology Innovation Programme, was developed to improve the understanding of the effect of marine turbulence on tidal arrays in Scottish waters.

Turbulence was measured by Partrac in the challenging tidal environments of both the Sound of Islay and the Inner Sound, Pentland Firth, using novel methods and technologies so that each can be evaluated, and turbulence could be mapped across differing tidal energy development sites. ABPmer then incorporated the data in resource characterisation, Ocean Array Systems (OAS) has provided turbulence characterisation and hydrodynamic analyses, and IT Power has contributed their knowledge of engineering design, device performance and tidal turbine array modelling. The project team used this wealth of information and research to develop Turbulence Guidance through extensive engagement with the tidal energy industry. 

Dr Tom Clark of Ocean Array Systems added “The project has mapped in detail the effects that marine turbulence has on tidal power installations. We demonstrated a practical and efficient end-to-end process for measuring, characterising and simulating the effect of site-specific turbulence. Finally, assessment of its impact on engineering design considerations highlighted the importance of properly accounting for turbulence – especially in considering yield and fatigue lifetimes”.

Full details are in the Guidance documents, which can be obtained at the wave and tidal knowledge network, a platform hosted by the ORE Catapult. The TiME project will also be represented in a pre-conference workshop at the International Tidal Energy Summit (ITES) at the Hilton Tower Bridge, London, UK, on Monday 23rd November, 2015.
