The pipe-laying vessel Pioneering Spirit in the Black Sea completed the offshore laying of the Turkish Stream gas pipeline.
The command to weld the closing joint of the second gas pipeline was given by Russian President Vladimir Putin and Turkish President Recep Tayyip Erdogan. “We welcome you. Please, start! ”- Putin said at the beginning of the ceremony, addressing the heads of Gazprom and Botash, Interfax reports.
Gazprom CEO Alexei Miller told the presidents of the Russian Federation and Turkey: “Together with the Botash CEO, we are 2.5 km from the Turkish coast on the ship Pioneering Spirit. The length of the vessel is 477 meters, it is the largest construction vessel in the world, with a displacement of 1 million tons. The construction of the Turkish Stream is a unique project – for the first time a pipe with a diameter of 813 mm was laid to a depth of 2.2 km. Two gas lines are constructed between the Russian Anapa and the Turkish settlement of Kiyik. The length of each of the threads – more than 930 km. The capacity of the pipeline is 31.5 billion cubic meters. meters of gas per year. This is enough to supply gas to 15 million households. ”
Oleg Aksyutin, a member of the board of Gazprom, added that the welding of the closing joint of the offshore section of the Turkish Stream gas pipeline has been completed.
“I ask you to give a command to launch the Turkish Stream gas pipeline into the sea by closing the junction,” Miller addressed the leaders of the two powers. “Start!” Putin answered.
Miller explained that after welding, an ultrasonic control of the seam is carried out, and an anti-corrosion coating is applied to the junction of the pipes. “This is exactly what makes it possible to ensure high reliability and environmental safety of the operation of the offshore gas pipeline,” he added.
“The average speed of pipe laying by ship is 4.8 km, but in August of this year, during the construction of the Turkish Stream, a new world record for laying large offshore gas pipelines was set at 6.330 km,” said the head of the Russian gas company.
“The closing joint is already on the stinger,” Miller said. “The pipe of the“ Turkish stream ”is closed by a closing joint into the water area of the Black Sea,” he concluded.
“Congratulations!” Putin answered. “Congratulations! Good luck! ”- Turkish President Recep Tayyip Erdogan said.
The Turkish Stream is a gas pipeline project from Russia to Turkey through the Black Sea and then on to the Turkish border with neighbouring countries. The first line of the gas pipeline is intended for the Turkish market, the second – for the countries of Southern and South-Eastern Europe. The capacity of each line is 15.75 billion cubic meters. m of gas per year. Work on the offshore section of the gas pipeline is carried out by South Stream Transport BV.
