Laying of the second line "Nord Stream" in Russian waters has ended, said the operator of the project — the company Nord Stream AG, RIA Novosti reported.
Today, the largest in its class vessel Allseas’ Solitaire has completed the laying of the second leg of the pipeline "Nord Stream" in Russian waters of the Gulf of Finland, and has continued to work in the waters of Finland. In total, more than 230 have already been laid second line kilometers, of which about 124 kilometers — in Russian waters. At the same time leads and pipe laying vessel Castoro Sei company Saipem. The first line is stacked full and will be put into operation in autumn 2011.
On the Russian shore in Portovaya near Vyborg in June also completed construction of the onshore facilities of both pipelines are built and successfully tested for strength. Thus, the complete basic set of construction work on the Russian section of the "Nord Stream", which consists of a coastal stretch of about 1.5 kilometers and the offshore section of 124 km.
Solitaire re-entered Russian waters for laying of the second line as scheduled on May 15. At 7.5 kilometers offshore vessel raised from the bottom line of the pipeline, the coastal part of which was placed a vessel Castoro Sei in the summer of 2010, and continued laying on the route. Due to favorable weather conditions, Solitaire pipe-laying rate was on average more than 3 kilometers per day, and the ship has paved 116 kilometers from the coast to the Russian waters of Finland in a little over a month. The same time in the first line "Nord Stream» Solitaire laid in September-October last year.
Onshore Facilities 1.5 kilometers from the coastline include the activation unit diagnostic and treatment devices, emergency shutdown valves and pipeline. Hardware installation is completed in June. At the moment, continues installation of telemetry and automation. This summer on the court system will be installed gas heating required at the stage of entering the gas pipeline.
The two threads of the Russian onshore section successfully passed the hydraulic test. In the next step, they are drained and filled with nitrogen to prepare for the supply of gas.
Earlier it was reported that the submarine completed the construction of the first pipeline "Nord Stream", docked with the coastal areas in Russia and Germany is planned for late summer. Thus, at present, all three sections of the first pipeline are now interconnected via underwater hyperbaric welding at two points on the bottom of the Baltic Sea.
Each of the two lines of the pipeline "Nord Stream" has 101 thousand 12-meter obetonirovannyh pipe diameter of 48 inches and a weight of 23 tons. Pipes of the first line were welded together on board special pipelay vessels and laid on the floor in a well-defined position.
Nord Stream is a fundamentally new route for Russian gas exports to Europe. Gas pipeline 1.22 thousand kilometers will run under the Baltic Sea from Russia (Vyborg) to Germany (Greifswald). The first phase capacity of 27.5 billion cubic meters of gas per year is scheduled for October 2011. Construction of the second line in 2012, will increase the capacity of Nord Stream to 55 billion cubic meters per year. According to the head of "Gazprom" Alexey Miller, it will be introduced in October 2012.
"Gazprom" has already signed long-term contracts for the supply of gas through Nord Stream to customers in several EU countries, including Germany, Denmark, the Netherlands, Belgium, France and the UK.
In the present shareholders of the Nord Stream project are "Gazprom", the German Wintershall Holding and E.ON Ruhrgas, French GDF Suez and Dutch Gasunie. The proportion of shareholders in the company’s project operator Nord Stream AG is as follows: "Gazprom" — 51%, Wintershall Holding and E.ON Ruhrgas — by 15,5%, Gasunie and GDF Suez — 9%.
