Cobra IS To Build Two Windfarm Energy Converter Platforms In The North Sea

The consortium made up of Dragados Offshore, a subsidiary of Cobra IS and Siemens Energy, has been awarded a contract by Amprion Offshore to design, build and install the LanWin1 and LanWin3 offshore windfarm energy converter platforms in the North Sea.

The converter platforms will collect the alternating current generated by several wind farms and convert it into high voltage direct current (HVDC), which will then be reconverted into alternating current at onshore stations approximately 400 km away. The onshore stations are also covered by the contract.


The construction of these platforms will take place at Dragados Offshore’s yard in Cádiz, Spain, and will generate over 2,000 jobs, providing workload until 2029.

With transmission and transport capacity of 2 GW each, i.e. a total of 4 GW, these platforms will be able to power a major city of 4 million people like Berlin. They are among the first of such capacity to be developed in northern Europe and are scheduled to be commissioned in 2029 and 2030.

Dragados Offshore is already executing four other offshore converter projects of this nature for German operators, under contracts that involve design, procurement, construction, transportation, installation and commissioning in the North Sea.
