The Gassled joint venture has approved a project to reroute the Norpipe gas pipeline.

The Gassled joint venture has approved a project to reroute the Norpipe gas pipeline, from Ekofisk in the North Sea to Emden in Germany, so that it bypasses the H7 riser platform. Subsea7 has been awarded a letter of intent for the main contract for planning and executing this operation. The job is worth NOK approximately 250 million NOK.

Running for 440 kilometres, Norpipe has been transporting gas from the Norwegian continental shelf to Germany since 1977. The system includes two compression platforms, H7 and B11, used to boost pressure in the pipeline and thereby drive more gas to market.

The need for pressure support was reduced and the H7 compression facilities were taken out of service in 1999. A project to remove this platform has been initiated as part of Gassled’s improvement programme, with the bypass as the first step.

“Plans call for the rerouting to take place in the summer of 2007,” says Atle Jan Gundersen, project manager in Gassco. “It will be coordinated with activities planned by operator ConocoPhillips on the Ekofisk field.”

The plans anticipate that H7 will be removed as part of the ConocoPhillips-operated project to dispose of other redundant installations in the Ekofisk area in the period 2006-13. A final decision on its removal will be taken next year.

Gassled owns Norpipe and H7, with Gassco as operator. ConocoPhillips serves as technical service provider for the platform, and employs the personnel working on it.
