Johan Sverdrup

Statoil has awarded a Nkr1.1bn ($155m) contract to Switzerland-based ABB for land-based power supply to the first phase of the Johan Sverdrup oil field development in Norway.

ABB will supply systems and equipment to two HVDC converter stations connecting the field with the onshore grid.

The company will design, engineer, supply and commission the equipment for two 80kV 100MW high-voltage converter stations.

The onshore station at Haugsneset will turn alternating current (AC) from the grid into high-voltage direct current (DC), which can be transmitted over 200km to the second station, which is on one of the oil platforms.

The DC current will then be converted back into AC and distributed to the rest of the field.

ABB process automation division president Peter Terwiesch said: "We are very pleased to be continuing our successful relationship with Statoil by delivering a third HVDC power-from-shore link.

"Using onshore electricity to run these oil platforms will eliminate the need for local gas-turbine power generation, significantly lowering CO2 emissions."

"Using onshore electricity to run these oil platforms will eliminate the need for local gas-turbine power generation, significantly lowering CO2 emissions, as well as operating and maintenance costs."

The Johan Sverdrup field, which is expected to cost in the range of Nkr170bn ($22.3bn) to Nkr220bn ($28.8bn), is estimated to hold 1.7 billion to three billion barrels of oil equivalent.

At plateau production, the field will account for approximately 40% of the total oil production on the Norwegian continental shelf. Operations are expected to start in late 2019.

Statoil will operate all phases of the field development and operation. The company’s partners include Lundin Norway, Petoro, Det norske oljeselskap and Maersk Oil.
