DEME Offshore has completed the installation of the 900MW DolWin6 high voltage direct current (HVDC) cable in the North Sea.
The marine contractor deployed its DP3 vessel Living Stone, powered by liquified natural gas to cut emissions, to install the cable that will connect to offshore wind farms.
Living Stone picked up the cables directly from the Nexans factory in Halden, Norway at the beginning of June and transported them to the offshore site in the German Bight.
DEME’s dedicated vessel has two turntables for installing bundled HVDC cables.
The HVDC cable pair was bundled together with the fibre optic cable on board Living Stone and installed.
DolWin6 is owned and operated by transmission system operator TenneT.
The HVDC cable runs from several offshore wind farms in Germany via Norderney to German mainland.
Bart de Poorter, general manager DEME Offshore Renewables, said: “We are pleased to see another campaign successfully concluded by our cable installation vessel ‘Living Stone’.
“Carrying out the project on LNG is another major milestone, highlighting once more the unrivalled technical capabilities of ‘Living Stone’ and its crew.”
