Gassco said that gas exports from Norway's continental shelf to Europe were 3.1bn cum higher than last year for the period ending 1 October, 2006. Jan Hauge, vice president for product management at Gassco, attributes the rise in sales to the start-up of the Kristin gasfield in the Norwegian Sea, and an expansion in capacity at the Karsto gas-processing plant north of Stavanger. Gas exports are likely to increase even further in the 2006 gas year, as new Langeled pipeline comes into operation. "The southern leg of Langeled (pipeline)... became operational on 1 October, expanding our export capacity to the UK. And we expect a rise in gas deliveries via Karsto," Mr Hauge said. The pipeline will have a capacity of 20bn cum/yr once it is connected to the Ormen Lange field. The UK's National Grid said that the southern leg currently has an import capacity of 68m cum/d of gas, roughly 16 % of the UK's daily peak gas demand. At 8.2bn cum, December was the peak month for Norwegian gas exports over the past year. Production of NGL and condensate from Karsto and the Kollsnes processing plant near Bergen, both operated by Gassco, was 9.7m tons in 2005, a 200,000-ton increase from the previous gas year. Gassco manages Norway's gas infrastructure system for Gassled, whose owners are Statoil, Norsk Hydro, ExxonMobil, Conoco Phillips, Royal Dutch/Shell, ENI, Total , and state-owned Petoro.
