Name Hywind Scotland Pilot Park correct
Other names Hywind II, Hywind 2, Buchan Deep correct
Country name United Kingdom correct
Region Scotland, Grampian correct
Comments Statoil Wind Limited (SWL) has been awarded an Exclusivity Agreement by The Crown Estate (TCE) for the deployment of floating wind turbine gererator (WTG) units in an area known as the Buchan Deep which is an area of deep water (95 to 120 m) located approximately 25 km off the coast at Peterhead, north east Scotland just outside the 12 nm territorial water limit. tyjtj

The Exclusivity Area is split into a northern and a southern part by the Forties to Cruden Bay pipelines which pass through the Exclusivity Area from north east to south west. The Pilot Park will be located either to the north or south of these pipelines. Electricity generated from the Pilot Park will be exported onshore to the local grid network via a new export cable to Peterhead.

The WTG units will be positioned approximately 720 to 1,600m apart. The WTG units will be attached to the seabed by a three-point mooring spread. The anchor types currently under consideration are drag embedded (fluke or plate), torpedo, suction embedded plate anchors, suction anchors and gravity anchors. Three anchors (or possibly six ) will normally be required per WTG unit. The mooring lines are likely to be composed of combinations of wire and chains and possibly synthetic fibre rope, and may include the use of clump weights and/or buoyancy elements. The radius of the mooring systems extending out from each of the WTG Units will be between 600 to 1,200 m. The WTG Units will be connected by inter-array cables which may require anchoring in some locations.

In addition to the proposed AfL Area and associated onshore and offshore infrastructure, the Hywind Scotland Pilot Park Project will use a deep water inshore area, the location of which is still to be determined, to assemble the

WTG Units prior to installation. Once assembled, the WTG Units will be towed in an upright position from the assembly point to the Buchan Deep.

The maximum life of the park is 25 Years.
