The gigantic Nord Stream pipe, with two same-sized parallel ones, runs from Vyborg in Russia through the Gulf of Finland and the Baltic Sea to Lumina in Germany. It will be able to secure supplies of electricity and heat to 26 million households in Europe for 50 years to come. The 1,224 kilometre-long pipe (approximately 760 miles) is currently located on the bottom in three lengths. Norwegian subsea expertise will be called upon to weld together the lengths of pipe on the seabed. The gas pipes’ diameters are 48 inches, thus making it larger than any other one placed on the seabed to date.
