The Irish Sea wind farm will use 108 Siemens 3.6MW machines, with completion scheduled for next year.

Iberdrola’s UK subsidiary ScottishPower Renewables is developing the project in partnership with Denmark's Dong Energy.

The work is being carried out by Swire Blue Ocean’s Pacific Orca and the A2SEA-owned Sea Installer.

Components are being shipped from the project's pre-assembly facility in Belfast.
