STAVANGER, Norway — Equinor and its partners plan to replace two gas turbines on the Statfjord C platform in the North Sea.
The measure is designed to cut the facility’s annual CO2 emissions by 95,000 metric tons with a new steam turbine producing electricity based on surplus heat from two gas compressors.
It will be the first such application on the Norwegian Continental Shelf (NCS), said Camilla Salthe, Equinor’s senior vice president for Field Life eXtension (FLX), and should help prolong production from Statfjord through 2040.
“Heat recovery for electric power production has been used on new fields, both on the NCS and internationally,” added Ketil Rongved, vice president for FLX projects. “Now, for the first time, the solution is introduced on a mature field in production. This is possible due to the development of low-weight solutions.”
The re-vamp will include electrification of water injection and emission cuts related to other energy-intensive processes on Statfjord C. Last month the Statfjord partnership dubbed the project “FLX Future Energy,” and the company said the "low weight bottoming cycle" solution does not require a power supply from shore.
Measures already implemented to clean up production at Statfjord include a heat recovery system installed on the Statfjord B platform in 2021, said to have cut CO2 emissions by 20,000 metric tons per year.
The partners in the Statfjord Unit are Equinor Energy (40.17028%), Okea (23.93123%), Vår Energi (21.36717%) and Equinor UK (14.53131%).
