China National Petroleum Corporation (CNPC) has started operating the third natural gas pipeline into Shanghai. The 55-mi. (88-km) line connects a coastal liquefied natural gas (LNG) terminal in Rudong, in Jiangshu province, with Shanghai’s Chongming island. The line has an annual capacity of 60 Tcf (1.84 Bcm), said CNPC, which also operates the other two gas pipelines to Shanghai – West-East Gas Pipeline and the Second West-East Gas Pipeline.
The new pipeline will help bolster supply to Shanghai, a city of roughly 24 million people, which has seen demand for natural gas increase sharply as China has worked aggressively to improve its energy infrastructure.
The West-East Gas Pipeline became operational in 2004. The 6300-mi. (5800-km) pipeline has an annual capacity of 600 Tcf (17 x 109 m3) (west section) and 423 Tcf (12 x 109 m3) (east section).
The Second West-East Gas Pipeline became operational in 2011. The 5408-mi. (8704-km) pipeline has an annual capacity of 1.05 Tcf (30 x 109 m3).
CNPC is China’s largest oil and gas producer and supplier, as well as one of the world’s major oilfield service providers. CNPC owns and operates pipeline networks and storage systems covering 29 provinces, municipalities, and autonomous regions as well as Hong Kong SAR in China. CNPC’s four major gas provinces – Tarim, Sichuan, Changqing, and Qinghai – produce about 80% of the nation’s total natural gas.
