The project company of the Nabucco gas pipeline said it has submitted to Azerbaijani gas field consortium Shah Deniz II a modified concept for the pipeline project, cutting its length to 1,300 kilometres from 3,900 kilometres planned earlier.
Under the new concept, called Nabucco West, the pipeline will bring Caspian gas from the Bulgarian-Turkish border to Baumgarten in Austria, Nabucco Gas Pipeline International said in a statement.
Initially, the pipeline was to be built from the Georgian-Turkish and the Iraqi-Turkish border to Baumgarten.
"We are convinced that we have submitted a competitive and comprehensive proposal to the Shah Deniz II Consortium, and that this proposal represents a win-win situation for our shareholders and for suppliers alike," Nabucco Gas Pipeline International managing director Reinhard Mitschek said in the statement.
According to the Nabucco website, the Shah Deniz Consortium has announced that it expects to make a final route selection ahead of mid-2013, and a decision for the central European section in the course of June 2012.
The Shah Deniz gas field in Azerbaijan is estimated to contain 1.2 trillion cubic metres of gas.
