SeaAngel foundation work begins

First concrete is being poured today for the foundation of the flagship 7MW Mitsubishi SeaAngel being erected at Scotland’s quasi-offshore Hunterston test centre.

The prototype, which had its original date slip from last autumn after knock-on delays linked to “difficult ground conditions” at its foundation location at the SSE-run coastal demonstration site in Clydeport, is now slated for June installation.

Turbine components for the SeaAngel should begin arriving in mid-May with erection planned for completion the following month.

The 7MW turbine flies 81.6-metre-long Eurus blades, which turn a drive-train based around hydraulic “digital displacement transmission” technology and a brushless synchronous generator.

The lead-off turbine being installed at Hunterston, Siemens’ 6MW SWT-6.0-154 machine, is curently being connected to the grid. Final commisioning is “anticipated by the end of next month”, according to the utility, and first generation should start in March.

Scottish Enterprise is inviting expressions of interest for leasing of the last berth, targeting switch-on by July 2015.

Hunterston has a wind resource that mirrors offshore conditions, making it well-suited to testing offshore turbine prototypes while having easy 24-hour access for modifications and repairs.
