Norway: Oil Channel Laying of Norway’s Largest and Longest Oil Pipeline in Progress
The work of connecting the pipeline to the Johan Sverdrup field began outside Mongstad, north of Bergen.
Norway – Soon the tip of the first pipe of what will become Norway’s longest and largest oil pipeline will be pulled into the Mongstad terminal, north of Bergen. The pipeline which will extend more than 280 km out to the Johan Sverdrup field once installed, is being pulled through a pre-drilled hole at the bottom of the Fensfjord into the oil terminal. When the Johan Sverdrup field produces at peak up to 600,000 barrels of oil will flow daily into Mongstad.
The costs for phase 1 of the Johan Sverdrup development have been reduced by more than 4 billion dollars since the plan for development and operation was approved by Norwegian authorities. The original plan was to route the pipeline onshore 10 km from the oil terminal. At the time, it was not assessed as technically feasible to lay the pipe through the Fensfjord due to other existing pipelines in the area and possible subsurface instability.
Statoil commissioned a study in 2015 which showed that a subsea pipeline route was possible as long as infill support for existing pipelines was in place. After thorough preparations, the conditions have been put in place for the pipelaying operations now underway.
