A2Sea's Sea Installer is heading for port after completing installation of the last turbines at the 389MW West of Duddon Sands wind farm.
The jack-up, working in water depths of 17-24 metres in the eastern Irish Sea, erected 108 Siemens 3.6MW turbines, along with 30 foundations for the project, being developed by Dong Energy and ScottishPower Renewables.
The vessel installed the first turbine in late September 2013, before ramping up to put in 44 in the last 63 days of the assignment as the Sea Installer transited to and from Belfast.
“This is an outstanding performance by the crew onboard Sea Installer, the project team and our colleagues at Siemens. It is a true example of our team-built culture at A2Sea, ” says chief executive Jens Frederik Hansen.
The Sea Installer, which can operate in waters down to 60 metres, will now mobilise for Dong's Borkum Riffgrund 1 project off Germany, where it will erect 77 Siemens 4MW turbines.
West of Duddon Sands, 14 km from Walney Island, northwest England, is slated to be producing power at full spate by the end of the year.
