Prysmian to build the COBRAcable interconnector

25 February 2016


Prysmian Group has won the €250 million contract to build the COBRAcable HVDC submarine interconnector that will link Denmark and the Netherlands. The contract was awarded by TenneT and Energinet.dk SOV, the Dutch and Danish TSOs.
The COBRAcable ('COpenhagen BRussels Amsterdam') is intended to increasing security of supply in both countries and enabling the further integration of renewable energy into the electricity grids. It will therefore contribute to the realisation of a sustainable international energy landscape, a key aim of the European Union, who is to support the project through the EEPR (European Energy Programme for Recovery).
Prysmian's role involves the turnkey supply and installation of the HVDC bipole, using single core cables with extruded insulation technology, operating at ±320 kV with a rating of approximately 700 MW. It will run along a total route of around 325 km, from Eemshaven in The Netherlands to Endrup in Denmark via the German sector of the North Sea, and will include two onshore lengths of 1 km on the Dutch side and 25 km on the Danish side to link to the onshore converter stations, which are to be provided under separate contract by Siemens. Delivery of the cable system is scheduled for the 3Q 2018.
All cables will be produced in Arco Felice (near Naples, Italy) and Pikkala (near Helsinki, Finland). Prysmian is currently building on recent investments made at its Pikkala factory with a further €10 million upgrade to existing production lines, to significantly increase its manufacturing capacity of extruded HV submarine cables.
The marine cable laying, which will be undertaken by Prysmian's own cable-laying vessels, the Cable Enterprise and the Giulio Verne, will also see the use of their newly acquired barge. Following the completion of its conversion in the next few months this barge extends Prysmian's range of installation capabilities by virtue of its suitability for shallow water cable installation.
