According to Bloomberg News, Hans-Peter Floren, natural gas director for Austrian energy company OMV, told delegates at the annual shareholder meeting that construction for Nabucco could start by 2015 and finish by 2018.
The news service didn't quote Floren, though Chief Executive Officer Gerhard Roiss said the project is "more important than ever." The Nabucco project description states construction would begin in 2013, with first gas flow expected by 2017.
In its investor report, which included financial statements as of March 31, the company said progress on the Nabucco gas pipeline depends on decisions made by the BP-led consortium working in the Shah Deniz 2 natural gas field in Azerbaijan.
BP proposed its South East Europe Pipeline in September. It would travel from eastern Turkey to the Austrian border. Nabucco West, a scaled-down version of the larger $10.4 billion pipeline, would follow a similar route.
BP had said it expects to make a decision on pipeline routes through Europe as early as next week.
