Nord Stream is a pair of offshore natural gas pipelines in Europe that run under the Baltic Sea from Russia to Germany. It comprises the Nord Stream 1 (NS1) pipeline running from Vyborg in northwestern Russia, near Finland, and the Nord Stream 2 (NS2) pipeline running from Ust-Luga in northwestern Russia near Estonia. Both pipelines run to Lubmin in the northeastern German state of Mecklenburg-Vorpommern. Each pipeline comprises two pipes, denoted A and B; each of the four pipes is approximately 1,200 kilometres (750 mi) long and with approximate diameters of 1,220 millimetres (48 in). The combined capacity of the four pipes is 110 billion cubic metres per annum of natural gas.
