Norwegian energy firm Equinor, alongside partners Vår Energi, LOTOS and KUFPEC, has made an investment decision to partially electrify the Sleipner field in the North Sea, offshore Norway.
To do so, the partners have filed a revised plan for development and operation to the authorities.
According to Equinor, the solution for the Sleipner field centre will require laying a new power cable from Sleipner to the Gina Krog platform, which will be tied into power from shore on the Utsira High by the end of 2022.
During the time when the power requirement is higher than the capacity in the area solution, Sleipner will use gas turbines to meet the demand.
Equinor noted that an investment decision has also been made on the Gina Krog electrification.
The Norwegian company estimates that the combined investment for the electrification of the Sleipner and Gina Krog will total approximately Nkr1.5bn ($160.4m).
Equinor Technology, Projects and Drilling executive vice-president Anders Opedal said: “Today, we are pleased to submit development plans for Sleipner electrification that will provide both ripple effects and major new emission cuts on the Norwegian continental shelf.
“This investment will contribute to further develop the NCS toward the goal of zero greenhouse gas emissions in 2050.
“Yesterday’s gratifying news that broad political agreement has been reached on temporary adjustments in the petroleum tax will provide the industry with the predictability it needs to continue work on planned projects that will stimulate new investments and maintain activity in a challenging period.”
Last October, oil and gas services firm Aibel secured a front-end engineering and design (FEED) contract to electrify Sleipner.
Equinor noted that this contract has now been expanded to an EPCIC contract.
In June 2019, Equinor announced plans to disclose datasets from the Sleipner offshore carbon capture and storage (CCS) plant to advance development and innovation in the CO2 storage field.
Operational since 1996, the Sleipner field is the world’s first offshore CCS plant.
