ABB has been selected to supply High Voltage Direct Current (HVDC) converters to electrify the first phase of the Johan Sverdrup field development project located 160km west of Stavanger in south-west Norway.
The Johan Sverdrup offshore field will have an estimated production peak of around 660,000 barrels of oil equivalent per day.
For the initial phase of the oil field development, which consists of four platforms, ABB’s HVDC system has a capacity of 100 megawatts (MW).
This phase of the project is set to cut emissions equivalent to 70,000 passenger cars per year.
ABB Norway Oil, Gas and Chemicals senior vice-president Borghild Lunde said: “The good cooperation between operator Statoil, engineering, procurement, and construction contractor Aibel, and ABB has contributed to excellent progress in the project.
“The onshore converter station is now online and ready for use.”

Once the offshore field is operational, a large amount of power will be transmitted, which will be primarily derived from renewable energy sources such as Norwegian hydropower.
The power will be enough to run 100,000 1,000W electric heaters at maximum heat.
According to operator Statoil, power from the shore to Johan Sverdrup offshore field through the 200km subsea cable is estimated to minimise greenhouse gas emissions by 80% to 90% when compared with an onboard generation of power by gas turbines.
The company estimates total CO2 reductions equivalent to 200,000 cars when the entire 300MW power from shore HVDC systems for the first and second phase of the project will be operational by 2022.
For the first phase of power from shore to Johan Sverdrup, ABB provides design, engineering, purchasing, installation, and commissioning of the HVDC systems onshore and offshore.
Set to operate at +/- 80 kilovolts (kV), the power link is scheduled for operation by the end of this year.
