The Dounreay Trì is a commercial demonstration project to be installed within a site approximately 9 km off Dounreay, Caithness off the north coast of Scotland. The design hosts two 5 MW wind turbine generators.
The platform turns into free wind around the third column of the triangular platform using a turret bearing and an electrical swivel. The turret is a solution being widely used in the oil and gas industry, where it has been proven for decades on e.g. FPSOs (Floating Production Storage and Offloading) vessels.
The electrical power is transported ashore by a single dynamic cable. It is subject to a Connection Offer from Scottish and Southern Energy Power Distribution, the associated onshore electrical infrastructure to connect the newly constructed substation at, or near, the existing Dounreay 33 kV substation. The substation include switchgear, protection, and local control.
Project Delivery Team
Dounreay appointed several well-respected parties in the renewables industry to execute the project such as Atkins, RES Offshore, ABS together with Hexicon.
Planning and construction started in March 2017 but the project is currently on hold. There is strong commitment from the project’s key suppliers to re-start the project and commissioning is planned for Q1 2020.
