Bringing power-from-shore to the platform complex in the North Sea lowers CO2 emissions, gives a reliable power supply, safer and better work environment on the platforms and reduced costs for operation and maintenance.
For equinor, Hitachi ABB Powergrids delivers the equipment for two ±80 kilovolt 100 MW HVDC Light® converter stations. One station is situated on-shore at Haugsneset, near the Statoil Kårstø plant on the Norwegian west coast, the other on the platform situated 200 km west of the Norwegian coastline.
The Johan Sverdrup installation located at Utsira Height is expected to become the largest producing oil field in the North Sea by the time it reaches its peak. In the first phase of the development plan four platforms will be built and production startup is in 2018.
Hitachi ABB Powergrids has won all four HVDC power-from-shore orders ordered in the world so far: Statoil’s Troll A 1&2, delivered in 2005, BP’s Valhall, delivered in 2011, Troll A 3&4, currently under delivery and now Johan Sverdrup. All are located in the North Sea.
