The sections will be joined together underwater in two locations: in the spring in the Gulf of Finland at the depth of 80 meters and in summer off the coast of the Swedish island of Gotland at the depth of 110 m. The start of natural gas transportation from Russia to the EU through the pipeline is scheduled for IV quarter of 2011. Construction of the second of the twin pipelines is scheduled for completion in 2012.
Upon completion of both lines in late 2012, Nord Stream will be able to transport 55 billion cbm of gas a year from Russia to Europe, enough to supply 26 million households. No other major new pipeline with a capacity over 10 billion cbm is expected to come on-stream before 2015.
The consortium pledges it will invest 40 million euros in integrated environmental monitoring program with approximately 1,000 survey locations measuring 16 parameters during construction and the first three years of operation.
