As on Statfjord, the transport solution was to load oil on the field while transporting gas in a pipeline tied into the Statpipe system at Statfjord B.
From there, the gas was piped for processing at the Kårstø plant north of Stavanger and then exported on to continental Europe via Ekofisk. As the satellite fields were brought on stream, however, gas production expanded substantially and created the need for a new export system.
The Gullfaks gas export pipeline system became operational on 16 March 2001. According to Harald Vandbakk, director for phase two of the Gullfaks satellites project, it would be able to handle the growing gas output from the whole area.
Export capacity from Gullfaks C was to be quadrupled to deal with gas from the Gullfaks South and Rimfaks satellite developments. The gas would be processed on the A and C platforms before being piped directly to Statpipe rather than by the earlier route via Statfjord.
As a result, the existing gas transport link from Gullfaks to Statfjord for connection to Statpipe was decommissioned. The new solution meant that Gullfaks gas deliveries could be stepped up from 13 million cubic metres per day to around 20 million, split roughly 50-50 between the A and C platforms. Peak daily output was about 25 million cubic metres in 2004.
