GeoSea will install its largest-ever monopile foundations at RWE’s 336MW Galloper offshore wind farm in the UK.

The DEME company has been appointed as EPCI contractor for foundations at the 56-turbine project in a deal worth €340m.

Each of the monopiles at Galloper will total more than 1100 tonnes, said GeoSea.

Installation of the substructures is due to kick off at the end of 2016.

Scour protection will be undertaken by Tideway, another part of the DEME group.

RWE is joined by Siemens, the UK Green Investment Bank and Macquarie in a four-way equity split at the wind farm.
