1. Overview and Historical Significance The Urengoy–Pomary–Uzhgorod gas pipeline (also known as the Western Siberian Gas Pipeline or the Trans-Siberian Pipeline in some Western sources) is one of the world’s largest and most strategically significant natural gas transmission systems. Built during the height of the Cold War (1982–1984), it was a landmark East-West energy project that connected the supergiant Urengoy gas field in Siberia to the borders of Western Europe via Ukraine.
