Abstract

The Turbulence in the Marine Environment (TiME) project, for the Carbon Trust, part-funded by the Scottish Government has delivered “Turbulence: Best Practices for the Tidal Power Industry” in three documents: 1. Measurement of turbulent flows 2. Data processing and characterisation of turbulent flows 3. Turbulence and turbulent effects in turbine and array engineering The project mapped the effects that marine turbulence has on tidal power installations and demonstrated a practical and efficient end-to-end process for measuring, characterising and simulating the effect of site-specific turbulence. Assessment of the impact of turbulence on engineering design considerations highlighted the importance of properly accounting for it – especially in considering yield and fatigue lifetimes. Part 1, Measurement of turbulent flows, addresses: • Commercially available (acoustic and non-acoustic) instruments for measurement of marine turbulence; • Instrument selection and limitations; • Instrument set up for turbulence investigation; • Site characterisation; • Survey planning and operations; • Data pre-processing, quality control and management. The project team comprised Partrac (measurement); ABPmer (resource characterisation); Ocean Array Systems (turbulence characterisation and hydrodynamic analyses) and IT Power (device design and performance, array modelling).
