Located in the East Irish Sea around 14km from the nearest coast on Walney Island, Cumbria, the project will feature 108 Siemens 3.6MW wind turbines and generate enough electricity to power over 300,000 UK households.

The offshore work includes installation of foundations and wind turbines, export and array cables, and offshore substation, while the onshore work includes the onshore substation, grid connection in Heysham, Lancashire, and building new bespoke O&M facilities for the project in Barrow-in-Furness.

Swire Blue Ocean’s Pacific Orca and A2SEA’s Sea Installer are undertaking offshore work of the project and expect to complete foundation installation by the end of October 2013.

The critical components, stored at a pre-assembly facility at Belfast Harbour, are all set to sail out to the construction site in the East Irish Sea.

ScottishPower Renewables project director Charlie Jordan said that the installation of the first turbine at the project is the result of the hard work of developers, as well as the contracting teams and suppliers.

"The operations at Belfast Harbour have been working well, and we are delighted with progress on the project," Jordan added.
