The Eastern Siberia–Pacific Ocean oil pipeline (ESPO pipeline, Russian: Нефтепровод “Восточная Сибирь – Тихий океан” (ВСТО)) is a pipeline system for exporting Russian crude oil to the Asia-Pacific markets (Japan, China and Korea). The pipeline is built and operated by Russian pipeline company Transneft.
The 4,857-kilometre (3,018 mi) pipeline is being laid by the route of Taishet-Kazachinskoye-Skovorodino-Kozmino. Because of protests of environmental organizations, the initial pipeline route was moved 40 kilometres (25 mi) north of Lake Baikal. Instead of going through Buryatia, it was built through Sakha Republic. The 2,757-kilometre (1,713 mi) long first stage runs from Taishet to Skovorodino and the 2,100-kilometre (1,300 mi) long second stage will run from Skovorodino to Kozmino. From Skovorodino the branch pipeline would extend through Mohe to Daqing, China.
There is a plan to lay a parallel Yakutia–Khabarovsk–Vladivostok gas pipeline alongside the oil pipeline.
The 2,757 kilometres (1,713 mi) long first stage of the pipeline, running from Taishet in Irkutsk Oblast to Skovorodino in Amur Oblast, was built by Systema SpecStroy, Krasnodarstroytransgaz, Vostok Stroy, Promstroy, Amerco Int. and IP Set Spb. Five 16V32 crude oil-fired engines for the pipeline-related power station were delivered in summer 2008 by Wärtsilä. The first stage of the pipeline with the total cost of US$12.27 billion and the export terminal with cost of US$1.74 billion are planned to be completed in the third quarter of 2009.
Construction of the 2,100 km (1,300 mi) long second stage from Skovorodino to the Pacific Ocean would start after launch of the first stage. It would be commissioned by 2014. In meantime, oil will be transported from Skovorodino to Kozmino by railway.
Spur to China
The 64 kilometres (40 mi) long section from Skovorodino to the Amur River on Russia-China border is built by Transneft and the 992 kilometres (616 mi) long section from Russia-China border to Daqing is built by the China National Petroleum Corporation. It was completed in September 2010.
The pipeline will be supplied from the oil fields of Tomsk Oblast and the Khanty–Mansi Autonomous Okrug in Western Siberia along the existing Omsk–Irkutsk pipeline that will join the new project in Taishet, as well as oil provinces of Eastern Siberia. At the initial stage 22 million tons of oil will be supplied by Rosneft and 8 million tons by Surgutneftegas.
