The 36 inch diameter, 447 km FLAGS Pipeline delivers gas from the Brent platforms in the North Sea to the St. Fergus Gas Terminal in Northwester U.k. Since the FLAGS Pipeline was commissioned in 1982, the use of the line has has incrementally increased due to the incorporation of additional gas sources into the offshore network, increased production from the existing fields and completion of the onshore gas treatment facilities.[6]

In 2007, The 25 million cubic meters of gas a day, 23.1 kilometer-long Tampen pipeline was commissioned. The pipeline ships gas from StatoilHydro's ASA (STO) Statfjord B field on the Norwegian continental shelf to the U.K. Flags pipeline and onto Scotland's St Fergus gas receiving terminal. The pipe cost 1.5 billion Norwegian kroner ($276 million).[7]
