The FLAGS (Far North Liquids and Associated Gas System) pipeline is a natural gas pipeline in the North Sea which is used to transport liquids and associated gas from the following fields:

• Cormorant A
• North Cormorant
• North West Hutton
• Ninian Central
• Ninian North & South
• Brent 'A', 'B', 'C' and 'D'
• Tern
• Magnus
• Thistle
• Murchison
• Statfjord
• Heather
• Gjøa
• Gas exported from West of shetland oil fields (Foinaven, Schiehallion/Loyal and Clair)
• Knarr

The pipeline is a 36-inch (910 mm) steel pipe to API 5L, X60 specification and is 450.6 kilometres (280.0 mi) long. It starts at Brent 'A' and terminates at St. Fergus near Peterhead in Scotland. Pipe laying was completed in April 1978 and finally commissioned in May 1982. The pipeline was laid by SEMAC 1.

At Brent A, the pipeline is connected with the Northern Leg and Western Leg transmission systems, carrying gas from a number of nearby fields. Natural gas from the Norwegian Statfjord field is fed through the Tampen pipeline, linking Norwegian and UK gas trunkline networks.
