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.
The pipeline runs 1,166 kilometres (725 mi) 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.

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 Europe.

The annual capacity of the Langeled pipeline is 25.5 billion cubic metres (900 billion cubic feet). That equates to some 20% of Britain’s peak gas demand. With the energy content of natural gas at 39 MJ (megajoules) per normal cubic meter, the capacity energy flux is 31.5 GW (gigawatts).

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.
