Equinor operates the Johan Sverdrup field, which is in the North Sea around 155 kilometres west of Karmøy in Rogaland county. The field is in development and production is planned to start in 2019.
Johan Sverdrup is one of the five largest oil fields on the Norwegian continental shelf. With expected resources of between 2.1—3.1 billion barrels of oil equivalents, it will also be one of the most important industrial projects in Norway in the next 50 years. The development and operation of this enormous field will generate revenue and provide jobs for coming generations.
In order to supply power to the field, PSA Norway allowed Equinor to use a facility. Electrical power will be obtained from the onshore grid and converted to DC at a transformer station at Haugsneset close to the Kårstø facility in Rogaland.
From there, a submarine cable will carry it through the Boknafjord, over the Norwegian Trench and out into the North Sea to the riser platform on the Johan Sverdrup field, where it will be converted to AC.
The field will be operated by electrical power generated onshore, reducing offshore emissions of climate gases by 80%—90% compared to a standard development utilising gas turbines on the NCS.
When in peak production, Johan Sverdrup will be supplying 25% of all Norwegian petroleum production at the time.
