Under the contract, Siemens will supply six gas turbine-driven compressor trains, each comprising an SGT-400 industrial gas turbine and a Siemens barrel-type STC-SV compressor.

The firm will also deliver three compressor trains to the compressor station in Kipoi, Greece.

Of the six compressor trains, three will be installed for pipeline stations in Greece while the remaining three in Albania.

The 870km pipeline project will allow transport of gas from the Shah Deniz II field in Azerbaijan in the Caspian Sea to the Italian market via Georgia, Turkey, Greece, Albania and the Adriatic Sea.

Designed to have an initial capacity of 10 billion cubic meters of gas per year, the TAP will also facilitate gas supply to several South Eastern European countries including Bulgaria, Albania, Bosnia and Herzegovina, Montenegro, Croatia and others.

Siemens Power and Gas’ Dresser-Rand business new equipment head Jesus Pacheco said: "With our extensive experience and broad product portfolio, Siemens was the choice to help TAP open up the Southern Gas Corridor and secure efficient gas transmission to Europe.

"We can help our pipeline clients mitigate risk and ensure safe and reliable operation at the lowest possible total lifecycle cost of ownership. Our comprehensive engineering expertise draws on a proven track record of experience to make sure everything works exactly as it should."

The pipeline, a part of Southern Gas Corridor infrastructure project, is scheduled to enter service in late 2019.

TAP consortium managing director Ian Bradshaw said: "Siemens was selected for its expertise, know-how and robust safety record in providing highly reliable gas turbine and turbo compressor units, which are an integral piece of our pipeline.”
