Jan De Nul Group has been contracted to carry out repairs of TenneT’s offshore high-voltage cables in the German Bight.
The scope entails repairs of all of TenneT’s existing HVAC cable systems connecting individual wind farms to the offshore convertor stations or directly to the onshore grid as well as repairs of all of TenneT’s HVDC cable systems connecting the offshore convertor stations to the onshore grid.
The contract covers a period of 24 months with two additional extensions of 12 months each.
Jan De Nul has already initiated the preparatory engineering works required to perform the cable repairs. In the event of an HV cable system fault or failure, the company will mobilise one of its offshore cable laying vessels, either Willem De Vlamingh (pictured) or Isaac Newton.
