Project Details

  • Operator: Gassco
  • Parent Company: Gassled
  • Current capacity: 25.5 billion cubic meters per year
  • Proposed capacity:
  • Length: 725 miles / 1,166 kilometers
  • Status: Operating
  • Start Year: 2006

Background

The Langeled pipeline (originally known as Britpipe) is an underwater pipeline transporting Norwegian natural gas to the United Kingdom. Before the completion of the Nord Stream pipeline, it was the longest subsea pipeline in the world.[2][3]

History

The project was launched under the original name Britpipe. In October 2003, Royal Dutch Shell, ExxonMobil and Statoil signed agreements to supply natural gas through the Britpipe.[4] The pipeline's construction began in 2004.[5] The largest part of the pipeline was installed by Acergy Piper, a pipe-laying ship of Acergy.[6] Other pipe-laying ships, which were used, are Solitaire (ship) of Allseas, and Saipem 7000 of Saipem.[7]

The pipeline was opened in two stages. The southern section (Sleipner Riser platform to Easington, East Riding of Yorkshire, began piping gas on 1 October 2006, and the northern section (Nyhamna to Sleipner Riser) opened in October 2007. The official opening of the project was held in London on 16 October 2006 by then-Prime Minister of the United Kingdom Tony Blair and his Norwegian counterpart, Jens Stoltenberg.[8]

Route

The pipeline runs 1,166 km through the North Sea from the Nyhamna terminal in Norway via the Sleipner Riser platform in the North Sea to Easington Gas Terminal in England.[6][9] The pipeline is designated to bring natural gas from the Ormen Lange gas process terminal to the UK, but through the connector at Sleipner Riser it provides also an opportunity to send gas through Gassco's existing network to continental Europe.

Technical description

The annual capacity of the Langeled pipeline is 25.5 billion cubic meters per year. That equates to some 20% of Britain's peak gas demand.[5] .

The Langeled pipeline supplements the Vesterled system with annual capacity about 12 bcm, which runs from Heimdal Riser platform in the North Sea to St. Fergus in Scotland.

The project cost £1.7 billion.[5]

Nyhamna-Sleipner Riser section

The Nyhamna-Sleipner Riser leg has a diameter of 1067 mm (42 in) and can operate with a pressure of 250 bar.[10]

Hub at Sleipner Riser

At Sleipner Riser the Langeled has a connection to the existing Gassled transport system.

Sleipner Riser-Easington section

The Sleipner Riser-Easington leg has a diameter of 1118 mm (48 in), which makes it the largest submarine pipeline in the North Sea.[10] Its pressure is 155 bar.

Ownership and operation

The owner of the Langeled pipeline is Gassled. The operator for Langeled is Gassco and technical service provider is Statoil. Statoil also runs the gas export project.[10] The principal funding of the project was provided by the syndicated loan structured by ABN AMRO and mainly subscribed by several banks, among them Barclays Bank, Royal Bank of Scotland, and Defoe Fournier & Cie.
