Finish line for Galloper

Posted by innogy on


innogy SE has confirmed that the last of the 56 Siemens Gamesa SWT-6.0-154 wind turbines has been installed at the Galloper offshore wind farm located 27km off the coast of Suffolk.

The 336MW project achieved financial close in November 2015 and over the last two years innogy has led construction of the project on behalf of project partners Macquarie Capital, Siemens Financial Services and Sumitomo.

Commenting on the milestone, Project Director Toby Edmonds said: “We only installed the first turbine in May of this year so it’s great to get it wrapped up in time for Christmas.  At 180 metres tall, these are the biggest offshore wind turbines we’ve installed to date plus we’ve installed them in water up to 36 metres deep, so quite a feat of engineering and construction.  This is a superb achievement made possible by a great team and great contract partners.  Our focus now is to finish off commissioning works and get to full power in  2018.”

Offshore construction kicked off in 2016 and saw the foundation installation campaign commence and the first export cable installed. The offshore substation, which was manufactured by Heerema at its fabrication base in Hartlepool on behalf of Alstom Petrofac Consortium, was completed in early May, along with the first turbine installation, and second export cable installation.

Swire Blue Ocean's jack-up installation vessel Pacific Orca was originally deployed to install the turbines at the site, operating from the Outer Harbour of the Port of Great Yarmouth. Fred. Olsen Windcarrier's jack-up vessel, Bold Tern was also mobilised to the site to ensure the timely completion of the project.

The wind farm represents an expected investment of around £1.5bn and is estimated that the average annual generation expected at the site will be equivalent to the approximate domestic needs of around 380,700 average UK households.

The Power Boost  feature incorporated into the 56 turbines increases the power output of each turbine by 5%, from 6.0MW to 6.3MW, and is enabled by increasing the rotational speed of the turbine during certain conditions, most notably when the wind speed is at its strongest.  This improvement to the turbine power curve can increase the power output of the wind farm from 336MW to 353MW.
