General Information Name Argyll Array Other names Tiree Array Country name United Kingdom Region Scotland, Highland Comments Water Depth Mostly 35m. Rotor diameter 108-175m. Hub height 80-115m. 4 to 6 Offshore Substations. If the AC/DC converter station is offshore, there will be 2 converters. If placed onshore (Tiree) there will only be 1 converter station. SPR is currently targeting an offshore converter as onshore is unlikely to get consent. Up to 4 met masts. Round (or category) Scottish Territorial Waters 1 Development status Concept/Early Planning Comments on the status In December 2012 it was announced that project development would be on hold for a year. The position will be reviewed at the end of 2013. The surveys have identified two key species that the project has the potential to impact; basking sharks and sea birds called Great Northern Divers that feed on the site in winter. Both species favour the shallow water around the Skerryvore Reef. In order to minimise potential impacts on birds including the Great Northern Diver, SPR are considering a revision to the design of windfarm to exclude either part or all of the Skerryvore Reef area, reducing the overall size of the windfarm. Doing this would also avoid the area where basking sharks are present as well as avoiding Skerryvore Lighthouse. Power & Turbines Notice any Errors?

Export Cables Please note that export cables connect the offshore transformer (substation) to either; shore or an offshore HVAC-HVDC converter station for onward transmission via HVDC cabling. Please see the converters page for planned converter stations and transmission cables. The export cable length does not generally include the onshore component. The exception is when the onshore substation is close to shore.

	Project parameters as given, seem perfect for TITAN, mobile self installing platform foundation. Big Turbines, 6 and 10MW's in waters 35 to 45 meters deep, in an environmentally sensitive area.
