Norway's natural gas exports were almost back to normal on Tuesday after several days' disruption due to the cold weather in Europe, Norwegian pipeline operator Gassco said. 'The situation has pretty much returned to normal,' Gassco spokesman Kjell Varlo Larsen told selfnews. A gas treatment plant in Kaarstoe in southwestern Norway and a processing facility for the offshore gas field Ormen Lange resumed operations after a weekend closure attributed to a build-up of ice in their pipes. 'The Kaarstoe plant has resumed production and is producing almost at full capacity,' Larsen said. Anglo-Dutch oil and gas company Shell said meanwhile that production at Ormen Lange, Norway's second-biggest gas field which normally supplies Britain, was 'slowly ramped up' after resuming operations on Monday. According to Gassco, Norway is the world's second-biggest gas exporter behind Russia. In 2009, the Scandinavian country exported some 96.6 billion cubic metres of gas by pipeline, primarily to Britain, Germany, France and Belgium.
