Sabella, a pioneering tidal and ocean stream turbine developer, has partnered with QOS Energy to improve the performance monitoring of its ground-breaking Ushant tidal energy project.
The first 1MW tidal turbine of the plant, immersed 55 metres under water off the west coast of France, is equipped with more than 100 sensors gathering data every 5 minutes. It now uses QOS Energy’s powerful data intelligence platform to identify, assess and anticipate potential failures.
Sabella’s 1MW D10 turbine was initially commissioned in 2015 in the Fromveur Passage, a strait that lies between Ushant Island and the Molène archipelago, off the coast of the French region of Brittany.
After undergoing key technology upgrades, the tidal turbine was redeployed for the second time in October 2018. Once again, the 400-tonne machine lies on the French seabed and captures the tide to provide renewable power to the 800 inhabitants of Ushant island. To optimise the turbine’s operation, QOS Energy and Sabella closely collaborated to develop specific data acquisition techniques and innovative analytics tailored to the constraints of the demanding sub-marine environment.
“Operating and maintaining a utility-scale tidal turbine at such depth is particularly challenging, and data collection and analysis plays a vital role in doing so successfully. QOS Energy’s data intelligence platform enables our O&M team to visualise critical KPIs such as water pressure, temperature, swell energy prediction, rotor speed or torque compared to power produced. We need this cutting-edge monitoring capability to be able to fully understand performance, and effectively control potential failures,” explained Jean-François Daviau, CEO of Sabella.
“Tidal turbine technology has great potential for off-grid islands that can now harvest their abundant tidal resources,” said Daviau. “Unlike most other sources of clean power, tidal energy produces renewable power in a regular and predictable manner, enabling operators to reliably forecast power production over the full life-cycle of a project.”
as in Southeast Asia and North America. With its innovative technology backed by successful pilot projects, the French company has acquired strong international recognition on the 75 to 100 GW global tidal market, which is expected to take off by 2020.
