HYD2M

Alderney Race hydrodynamics: measurements and modelling

Context

Improving energy production estimation is a key aspect of research in the field of offshore renewable energy. The typical error in tidal current prediction at tidal energy sites is about 10%, which results in a 30% error for the tidal power estimation. To reduce these errors, wave-current interactions need to be correctly taken into account in hydrodynamic numerical models.

Objective

To determine the yield of different turbines at a tidal farm in the Alderney Race, taking into account local hydrodynamics and sea states

Main achievements

In-situ and high-frequency radar observations to obtain a better understanding of wave-current interaction processes, and thus fine-tune the configuration of numerical models

Construction of a numerical platform for the prediction of hydrodynamics in the Alderney Race

Main outputs

Mapping of hydrokinetic resources by HF and VHF radar
Three-dimensional, high-resolution maps of currents calculated taking into account the sea state
Current database from ADCP measurements and video images of the nature of the sea bottom
New algorithm for processing radar data acquired in extreme environments
High-resolution configuration of the circulation and sea state models for the simulation of the hydrodynamics of the Alderney Race
Improvement of numerical models for the representation of three-dimensional dynamics
New algorithm for the simulation of the producible at tidal turbine and farm scales

Conclusion

HYD2M provides a wealth of data and knowledge on the hydrodynamics of the Alderney Race area, which is conducive to the deployment of tidal turbine systems. The data acquired during the project have been integrated into a model that is now available to support the actors of the hydrodynamic sector in the estimation of the hydrodynamic production in the Alderney Race area.
