Norpipe constitutes an underwater pipeline network in the North Sea designed to transport crude oil from the Norwegian Ekofisk and nearby fields to the United Kingdom, while simultaneously conveying natural gas to Germany.

Oil pipeline

The Norpipe oil conduit commences at the Ekofisk 2/4-J installation. It facilitates the transfer of oil from Ekofisk—including Cod, West Ekofisk, Tor, Albuskjell, Eldfisk, Edda, and Embla—as well as from Norwegian sites such as Valhall, Hod, Gyda, Ula, Tambar, and Oselvar. Additionally, it serves UK fields like Fulmar and Judy. A connection point for UK fields is situated approximately from Ekofisk. The pipeline terminates at the Teesside Refinery located in England.

Extending over , the pipeline has a diameter of . It is owned by Norpipe Oil AS, a joint venture comprising ConocoPhillips Skandinavia AS (35.05%), TotalFinaElf Exploration Norge AS (34.93%), Statoil (18.5%), Eni Norge AS (6.52%), and SDFI (5%). Operational control lies with ConocoPhillips Skandinavia AS. Since its commissioning in 1975, regulatory permissions allow its operation through to 2028. The booster pump platforms located in the UK sector were decommissioned by 2010 as part of the Ekofisk field shutdown activities.

UK fields linked to Norpipe

Numerous UK oil fields utilize the Norpipe system for exporting their production:

This infrastructure enables streamlined exportation of North Sea hydrocarbons through Norpipe into the UK market.

Throughput

Between 1998 and 2021, annual oil output (measured in 1,000 tonnes) experienced a reduction from 7,619 in 1998 to 1,772 in 2021. By the conclusion of 2021, the terminal's cumulative oil throughput had reached 104.585 million tonnes.

Natural gas pipeline

The Norpipe natural gas pipeline, spanning 440 kilometers, links the Ekofisk field to a reception facility located in Emden, Germany. Featuring a diameter of 36 inches, this pipeline possesses an annual capacity of 16 billion cubic meters of natural gas. Commissioned in 1977, it is projected to remain operational until 2028. The initial capital expenditure amounted to 26.4 billion Norwegian krone. Ownership is held by Gassled, with Gassco responsible for operations and ConocoPhillips providing technical support.

On September 30, 1995, the German cargo vessel Reint collided with the Norpipe H7 platform situated on the German continental shelf. The incident resulted in minor damage and no casualties. The H7 platform was decommissioned in 1999, and in 2007 a bypass pipeline was constructed to circumvent it.
