Aker BP expects to reduce CO2 emissions from Edvard Grieg and Ivar Aasen production platforms by 200,000 tonnes/year (tpy) now that the two North Sea Utsira High area platforms are operated with electric power from shore.
Two gas fired turbines have been shut down, thus reducing greenhouse gas emissions by some 3.6 million tonnes over the life of the field as well as reducing operating costs since the company no longer operates its own power plant on the platform, said Kari Nielsen, asset manager Edvard Grieg and Ivar Aasen, Aker BP, in a release Dec. 7.
The gas-powered turbines on the Edvard Grieg platform have supplied both fields with the necessary power and heat since start-up in 2015 and 2016, respectively (OGJ Online, Nov. 30, 2015; Dec. 30, 2016).
Edvard Grieg was prepared to receive electricity from shore from the construction phase in 2012 to fulfill requirements from authorities. In 2014, Parliament decided that a solution for power supply from shore should be developed for Johan Sverdrup, and the other installations in the Utsira High area should be connected in conjunction with phase two of Johan Sverdrup development.
The project has been carried out as two sub-projects—one for seabed cable installation between Johan Sverdrup and Edvard Grieg, and one for development and installation of a solution with electric boilers for heat required in the process plant (OGJ Online, Sept. 29, 2020).
