Edvard Grieg reduces emissions by 200.000 tonnes CO2

Lundin Norway will together with licensees modify the Edvard Grieg platform so that both power and heat needs are met with electricity from shore. This will yield a CO2 emission reduction of approximately 200,000 tonnes per year.

The plan is for the platform to be supplied with power from shore starting from 2022. Today, power is generated using a gas turbine equipped for heat recovery. When the platform is supplied with power from shore, electric boilers will cover heating needs in the process plant on the platform.

In connection with Phase 2 of the Johan Sverdrup field development, a power from shore solution will be established for the installations in the southern part of the Utsira High in the North Sea. A subsea cable will be laid from the Johan Sverdrup field centre to Edvard Grieg.

“It’s a substantial investment, but we see many advantages in supplying the platform with power from shore,” says Managing Director Kristin Færøvik.

“By shutting down the gas turbine on board we can reduce CO2 emissions by a volume corresponding to 100,000 private vehicles. This also reduces operating costs since we will no longer have to operate our own power plant offshore, and we will achieve more stable production,” says Færøvik.

The Edvard Grieg platform was prepared to receive electricity from shore all the way from the construction phase in 2012. This was also a requirement set by the authorities. In 2014, the Storting (Norwegian Parliament) decided that a power from shore solution would be built for Johan Sverdrup, and the other platforms in the area would be connected to this solution in conjunction with Phase 2 of the Sverdrup development.

“Receiving power for a platform via cable has been done before. But producing the heat needed in the process facility has required qualification of technology”, says Operations Director Kari Nielsen.

“We are confident that electric boilers will be a good solution, and it is also what the Edvard Grieg license parnership recommendes,” says Kari Nielsen.

When the area solution for power from shore is fully in place by 2022, oil and gas production from the Utsira High will have among the lowest emission rates in the world, with less than 1 kilo CO2 per produced barrel.
