Recovery of D10 tidal turbine

During the night of April 10th-11th, 2019, in the Fromveur Passage, the D10-1000 turbine was successfully lifted from its gravity-based foundation. 

After a very satisfactory operating period of the tidal turbine following its redeployment in October 2018, as part of the European ICE project led by Bretagne Développement Innovation and its partners, and a continuous electricity production over several months at the end of last year, SABELLA's team focused on testing new control methods at the beginning of 2019 in order to significantly improve the efficiency of the turbine and contribute to the competitiveness of this emerging sector. In parallel, a defect was detected in the nacelle’s cooling system that allows the various components integrated into the nacelle to be cooled. This defect did not prevent the operation of the turbine but limited its operating conditions due to the possible rise in temperature of the components, which could cause greater damage on the electrical chain.  

SABELLA thus seized the opportunity of the nearby presence of Olympic Zeus and chose to retrieve its turbine for a short maintenance operation of approximately 3 months at the port of Brest.
