Seabed cable stability and hydrodynamics
The development of tidal turbine arrays requires managing the costs of stabilising electric cables on the seabed in the presence of strong currents. Existing methodologies are suitable for sites where cable instability is mainly related to wave action. The very specific nature of strong currents found at tidal sites requires an adaptation of these methodologies taking into account turbulence in the currents combined with waves and chaotic bathymetry.
STHYF has enabled the development of models to study the stability of cables in a tidal environment, whihch means on rocky ground and with high current speeds in the water column. These models have been integrated into software tools which are available to support the actors of the tidal sector in the design of future farms.
This project was led by EDF and France Energies Marines.
This project received French State funding managed by the National Research Agency under the Investments for the Future Programme (ANR-10-IEED-0006-20).
This project was certified by the maritime cluster Pôle Mer Bretagne Atlantique.
