French renewables developer Sabella has removed its D10-1000 tidal turbine from the Fromveur Passage off the coast of France to perform maintenance.
The recovery work was carried out by Inyanga Maritime using the Olympic Zeus vessel.
Sabella said the removal followed a “very satisfactory operating period” after redeployment in October 2018, as part of the European ICE project led by Bretagne Developpement Innovation.
However, during the tests a defect was detected in the nacelle’s cooling system that allows the various components to be cooled.
Sabella said the defect did not prevent the operation of the turbine but limited its operating conditions due to possible temperature rises of the components, which could cause greater damage on the electrical chain.
The D10-D1000 will undergo servicing for about three months at the port of Brest to resolve the problem and also to review the conditions of the device's other components.
Sabella said the technology will be redeployed and connected to Ushant Island grid at the beginning of the summer for operation until 2021.
