The company said that two of three sections of line 1 of the natural gas pipeline have now been completed.
In total, more than 83,300 pipe segments have been laid over a distance of 1,000km.
The remaining part will be constructed by Saipem’s Castoro Sei pipelay vessel by April 2011, according to the company.
The connection of the three major pipeline sections will be carried out at the two offshore locations where the design pressure changes from 220 to 200 bar and from 200 to 170 bar respectively.
The Gulf of Finland and central sections will be connected off the coast of Finland in spring at a sea depth of approximately 80m.
The connection of the central and south-western sections off the coast of Gotland, Sweden, to take place in summer at a depth of approximately 110m, will mark the completion of construction of line 1.
