DEME subsidiary GeoSea’s jack-up vessel Innovation has installed the first monopile at the 396MW Merkur Offshore wind farm in the German North Sea.

The Steelwind-manufactured foundations were loaded out in Vlissingen, Netherlands.


The vessel (pictured) will also be deployed for installation of transition pieces, supplied by Spanish shipyard Idesa. 

Internal cabling is scheduled to start in September. DEME’s new subsea cable installation and trenching vessel Living Stone will install Nexans inter array cables.

The jacket for the Iemants and Engie Fabricom-Tractebel-built substation will be installed in November, followed by the topside in January 2018. 

Jack-up Seafox 5 will install 66 Haliade 150-6MW machines at the construction site some 45km north of the island of Borkum. 

TSO TenneT is expected to connect Merkur Offshore to the Dolwin gamma grid hub in August 2018.
