Dutch offshore service provider Jan De Nul has been awarded a framework agreement by TenneT for offshore high-voltage cable repair works in the German Bight.
The scope of the contract entails repairs of all 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 TenneT’s HVDC cable systems connecting the offshore convertor stations to the onshore grid. In addition, any future connections commissioned within the duration of the agreement will be added to Jan De Nul’s scope. The contract covers a period of 24 months with two optional extensions of 12 months each.
Jan De Nul Group has already initiated the preparatory engineering works and it will mobilise one of its offshore cable laying vessels, either Isaac Newton or Willem de Vlamingh, in the event of a HV cable system fault or failure.
Last year, Willem de Vlamingh installed HV cables to connect the Trianel Windpark Borkum and Borkum Riffgrund II wind farms to TenneT’s DolWin Gamma and Alpha offshore convertor stations.
“We are delighted for Jan De Nul Group to be selected as the cable repair contractor for TenneT’s HV cable system. This agreement continues our trusted relationship with TenneT and furthers Jan De Nul’s position as a reliable and experienced cable installation contractor,” said Wouter Vermeersch, manager of offshore cables at Jan De Nul Group.
