NORWAY  Windstaller Alliance, the joint venture between Aker Solutions, DeepOcean and Solstad Offshore, has been subcontracted to deliver the FEED for the subsea installation scope of the FloWatt Tidal Pilot to be installed offshore Normandy, France.

The study is financed by “The Tidal Stream Industry Energiser Project” (TIGER) EU program.

The FloWatt project incorporates 7 x 2.5 MW tidal turbines of Hydroquest technology – 17.5 MW in total – which will make it the world’s most powerful tidal power farm, Windstaller says. It is located in the Raz Blanchard passage at the northwestern tip of France.

To deliver its FEED installation scope, Windstaller Alliance will draw upon the experience of Aker Solutions’ subsea power distribution, DeepOcean’s subsea power cable installation and Solstad Offshore’s installation of tidal water turbines. The FEED covers installation of a subsea HV power collection system, which connects seven of the 2.5-MW tidal turbines to a subsea connection hub, interarray cables and power export cable to shore.

Windstaller will deliver its FEED installation scope as a subcontractor to Aker Solutions, which has been appointed by HydroQuest to deliver the complete FEED study for Subsea Interconnection System of the FloWatt project. The FEED will be completed in the summer of 2023. 

The FloWatt project, developed by HydroQuest and Qair, expects final investment decision in 2024, with potential EPCI contract award the same year. 

“There is a lot of cross-over between installation of subsea power equipment for tidal power and offshore wind. In principle, it is about safely and cost-effectively making the necessary installations to connect the subsea equipment offshore and install the equipment required to bring the power to shore. This is what Windstaller Alliance does,” said Guro Høyaas Løken, head of the Windstaller Alliance.
