Gazprom reveals Nord Stream pipe blowout
The increase comes from added expenses in building two lines of the 1,200-kilometre pipeline.
Construction of the onshore segment began in 2005 with an estimated total project cost of $US6.3 BLN. Gazprom revised the cost estimate 6 months ago to $US9.5 BLN.
Construction of the underwater segment, which will link Russia and Germany across the Baltic Sea, has yet to begin.
Nord Stream shareholders will provide 30% of project cots, with the remaining left to be borrowed.
