Atlantic Array

Developer: RWE

Site Size: Covering an area of approximately 200km².

Site Location: The wind farm would be located in the ; around 16.5km from the closest point to shore on the North Devon coast, 22.5km from the closest point to shore on the South Wales coast and 13.5km from Lundy Island. Predominant swell in this area is south westerly, caused by low pressure in the mid-Atlantic. The areas most affected will be along the welsh coast; including surfing beaches Tenby South Beach (49km) to Porthcawl (51km). Other nearby surf spots that are less affected are between Lynmouth (35km) to (38km) Barley Bay to on the North Devon Coast.

Technology: The proposed project would have a maximum of 240 generators, 4 offshore substations, 5 meteorological stations and other associated infrastructure. The maximum installed capacity would be 1200MW, enough to meet the average energy needs of up to 900,000 homes. Last Update 12/09/2013

The turbines will be one of three sizes; 5MW, 6MW or 8MW capacity. The proposed design envelopes for the turbines are:

Indicative Turbine Max.Number Indicative Hub Max Rotor Max blade tip Size (MW) Height (m*) Diameter (m) (m*) 5 240 110 140 180 6 200 115 165 200 8 150 125 180 220 *m above LAT(Lowest Astronomical Tide)

Foundations for the turbines are yet to be confirmed and will be of the following:

• Multiple and Jacket Foundations (piled lattice towers) - A typical foundation would consist of 4 legs held together by lattice framework, penetrating to 19m. However there is the possibility of the foundation being 3 legged or having a ‘twisted’ jacket function.

• Tripod and braced column structure variants – Differ from jackets in that they comprise a number of tubular membranes that are pinned to the seabed, the legs support a single column to support the tower and turbine. A braced column structures are all based on a single large column, with variation in bracing geometry and founding method.

• Gravity Based Structures – Several GBS designs have been suggested, such as conical, flat, buoyant and hybrid structures. Material will be a mix of reinforced concrete and steel. It is likely that seabed levelling and input of material to form a stable base will occur. The worst case scenario will see an area of 105m² will be affect by seabed preparation.

• Suction Monopods – Utilises a single suction caisson to support a steel/concrete columnar structure. Each monopod will have a maximum diameter of 20m and the caisson height above seabed will be 2m with a penetration depth of 19m.

• Floating concepts – Comprise of a submersible platform, attached to the seabed by a variety of different mooring systems.

The foundations for the substations and meteorological stations are likely to be from the same range as presented for the wind turbines.

One large export cable will be used to connect the offshore substations to the onshore cables at the landfall point. The cable will be buried where feasible to do so; otherwise cable protection will be layed. The export cable landfall is located to the south of Westward Ho! At Cornborough Range. Using Horizontal Directional Drilling the export cable will be installed in ducts beneath the exposed rock structure and will exit in the seabed at a depth of 5m (LAT).

Development Stage: The application was withdrawn by the developer on 26/11/2013 due to technical issues.

Surfers Against Sewage have concerns due to the proximity of the proposed project to significant surf beaches in North Cornwall, North Devon and South Wales. Jacket foundations have been highlighted as have the biggest impact on wave resources.

This Project has now been halted due to technical issues.
