ZWIJNDRECHT, Belgium – DEME Offshore’s cable lay vessel Living Stone has installed the DolWin6 high voltage DC (HVDC) cable in the German North Sea.
This is the first time a cable laying vessel has installed cables while powered on LNG, according to the company.
At the beginning of June, the Living Stone picked up the cables from the Nexans manufacturing facility in Halden, Norway, and transported them to the offshore site in the German Bight.
The DP-3 vessel has two turntables. The HVDC cable pair was bundled together with the fiber optic cable onboard the Living Stone and installed.
DolWin6 has a transmission capacity of 900 MW and is owned and operated by TenneT. The HVDC cable runs from several offshore wind farms in Germany via Norderney to the German mainland.
