TAP Managing Director Kjetil Tungland told delegates at a natural gas forum in Brussels that getting natural gas from Azerbaijan was vital for regional energy security.
"TAP is the only pipeline which can fulfill this vision in a cost-effective, technically reliable and commercial way," he said.
TAP would move natural gas from the Caspian region to European markets. It would start near Komotini, Greece, go through Albania, the Adriatic Sea and reach shore in southern Italy.
TAP last month sent third-party access exemption applications to the host countries that would let the consortium enter into a ship-or-pay gas transportation agreement with shippers working in the Shah Deniz II field in Azerbaijan.
Baku is expected to soon choose from a number of gas transit networks outlined in the so-called Southern Corridor, which includes TAP and the Nabucco project.
"Connecting southeastern Europe to Caspian gas supplies will diversify the region's energy sources and contribute to the creation of a truly pan-European gas market," said Tungland.
