The COBRA cable project consists of the power link between Denmark and The Netherlands and it has been developed by Energinet.dk and TenneT TSO B.V. The purpose of COBRA Cable is to allow for the integration of more renewable energy into the Dutch and Danish power systems and to increase the security of supply. The power link will also help to intensify competition in the north-west European power markets. Strong power links between the European countries make it possible to integrate markedly more wind energy into the European power systems.

The cables system that was installed is composed by:

  • 2 High Voltage Direct Current (HVDC)
  • 1 Fiber Optic (FO) cable

Prysmian Group has awarded Assodivers Group the cable installation and protection operations (Simultaneous Laying/Burial) of German offshore sections of the route.
