The Dounreay Trì project is a commercial demonstration that will be installed off the North coast of Scotland within a site about 9 km off Dounreay, Caithness. Hexicon has developed a semi-submersible foundation for offshore wind power that is intended to support any turbine. The Dounreay design hosts two 5-MW wind turbines.
The platform pivots on a third column of the triangular platform using a turret bearing and an electrical swivel.

A single dynamic export cable brings the power ashore. 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 will include switchgear, protection, and some local control.
