Arriving from temperature, before being transported further through the Baltic Sea from Russia, and exit at offshore in the Bay of Greifswald, Nord Stream’s twin the OPAL (Baltic Sea Pipeline Link) and NEL (North the German mainland at the Lubmin pipelines reach land near Lubmin’s harbour area. The European Gas Pipeline) connecting pipelines. The landfall facility. Here, gas from Nord natural gas that is transported through Nord Stream 472 kilometre OPAL pipeline runs south from Lubmin Stream is prepared before being starts its journey in Portovaya Bay, near Vyborg, to Brandov in the Czech Republic, while the 441 Russia – some 1,224-kilometres away. When the gas kilometre NEL pipeline runs westward across northern transported onward through the reaches the landfall facility in Germany, it is cleaned Germany to Rehden in Lower Saxony. Combined,the European pipeline grid. of potential impurities in special filters, and heated three interconnected pipeline systems are capable of for further pressure reduction. At the landfall, the transporting about 55 billion cubic metres of gas to incoming and outgoing gas streams are also checked European users.
