* Russia seeks to increase market share in Europe
* Route via Germany, bypasses Ukraine
* Gazprom upbeat on gas demand, ups '10 output forecast

VYBORG, Russia, April 9 (Reuters) - Russian President Dmitry Medvedev on Friday launched the construction of a major gas pipeline aimed at winning market share in Europe while bypassing Ukraine, where strained relations have caused supply disruptions in the past.
Nord Stream, a project involving Gazprom (GAZP.MM), Germany's BASF BASF.F and E.ON (EONGn.DE) as well as Dutch firm Gasunie, is expected to help Russia increase its share of EU gas markets from the current 25 percent to about a third.
"The demand for the 'blue fuel' -- we are all sure of this -- will continue to grow in Europe," Medvdev said at the launch. Germany's Chancellor Angela Merkel joined by video link.
The pipeline -- which will cost 8.8 billion euros ($11.77 billion) -- plans to transport up to 55 billion cubic metres of gas per year from 2012. Gazprom said that contracts have already been signed for most of the volumes.
One possible fly in the ointment is the increasing popularity of alternative fuels, such as shale or liquefied gas. But Nord Stream officials have said this should not undermine Russia's leading role in the European market. [ID:nLDE6371ZD]
Nord Stream, Russia's biggest post-Soviet gas pipeline, will ship gas under the Baltic Sea to Germany and onward to other European nations.
That will allow more Russian gas exports to bypass Ukraine, through which 80 percent are currently routed. Differences with Kiev also encouraged Moscow to speed up the project, as well as South Stream, running north and south of the EU bloc.
In January 2009, Russian gas supplies to Europe came to a halt for almost two weeks as Moscow and Kiev rowed over prices and transit terms.
Gazprom CEO Alexei Miller said Nord Stream will "ensure the highest reliability of supply".
Gazprom saw a big slump in demand in Europe last year due to the economic crisis and as clients preferred to buy cheaper liquefied and spot pipeline gas.

However the company is upbeat about prospects this year.
"The pace of the market recovery is very, very great," Miller said, adding that "based on the results of the first quarter" Gazprom would likely produce 529 billion cubic metres of gas, up from a previous plan of 521 bcm.
Under the Nord Stream network, two parallel pipelines would together carry gas over 1,200 km (750 miles) from Vyborg in Russia to Greifswald in Germany under the Baltic Sea.
The first leg will carry 27.5 bcm starting from 2011, the second link is expected to be completed in 2012. The link will cross the waters of Russia, Sweden, Denmark and Germany as well as Finland. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
