Client: Andritz Hydro Hammerfest
Project: Tidal Resource Assessment at EMEC in Orkney

Andritz Hydro Hammerfest is a tidal turbine developer based in Glasgow. Digital Engineering worked in partnership with the client and experts at Cranfield University to evaluate an innovative methodology for tidal resource assessment. The work formed part of a study related to Andritz Hydro Hammerfest’s tidal energy test bay, at the European Marine Energy Centre (EMEC) test site in Orkney.

The Tidal Resource Assessment combined the hydro-acoustic measurements of current velocities at the site, gathered by an Acoustic Doppler Current Profiler (ADCP), with high-resolution computational fluid dynamics models of the channel and tide characteristics.The modelled results were found to be in line with the ADCP measurements at the measuring locations.

Our tidal resource maps helped to augment Andritz Hydro Hammerfest’s understanding of the current patterns in the channel and explained some of the observed trends in the measured data. The study also provided useful guidelines for modelling tidal flows in challenging bathymetries and complex coastal lines.

Sample models from the project can be seen below.
