The Sleipner area embraces the gas and condensate fields Sleipner Øst, Gungne and Sleipner Vest. The Sleipner installations are also processing hydrocarbons from the tie-in fields Sigyn, Volve, Gudrun and from 2017 also rich gas from Gina Krog.
Sleipner consists of the following installations:
- Sleipner A - Processing, drilling and Living quarter platform
- Sleipner R - Riser platform for gas export and condensate export
- Sleipner T - Processing and CO2 removal platform
- Sleipner B - Unmanned production platform
Sleipner T and Sleipner R are both connected permanently with a bridge to Sleipner A platform.
Sleipner B is unmanned and is periodically operated by operations and maintenance personnel transferred from Sleipner A in helicopter.
Sleipner has since 1996 performed removal of CO2 from produced gas, and injected and stored more than 16 million tonnes of CO2 in the Utsira formation.
The production from the subsea field Sigyn and gas export from Volve installation is processed on Sleipner A.
In 2014 the processing of Gudrun rich gas and unstable condensate started up at Sleipner.
Start-up of the processing of Gina Krog rich gas at Sleipner is planned in 2017.
Start-up of the processing of Utgard well stream to Sleipner is planned in ca 2020.
Transport and gas-hub:
Sleipner delivers dry gas into Gassled pipeline infrastructure (Area D) and unstable condensate to Kårstø for further processing and export.
Sleipner R is also a gas hub for gas from Kollsnes (Zeepipe II) and from Nyhamna (Langeled) for further transport to Draupner, Zeebrugge and Easington.
