The 448km (278mi)-long Zapolyarye-Purpe oil pipeline construction in the Yamalo-Nenetsk region, Eastern Siberia, commenced in March 2010. The pipeline, intended to transport up to 45 million tonnes of oil a year, was completed by the end of 2016 and commissioned in January 2017.
The new pipeline links the untapped oil deposits located in Arctic Siberia to the main pipeline grid, as well as connect fields on the Yamal Peninsula to the Eastern Siberia-Pacific Ocean pipeline (ESPO). The pipeline is being operated by OAO AK Transneft.
It was constructed as part of the Zapolyarye-Purpe-Samotlor pipeline system, which is aimed at supplying crude oil from major new fields in the Yamalo-Nenets autonomous district and northern Krasnoyarsk territory to oil refineries in Russia. The oil processed at the refineries is exported to the Asia-Pacific region.
The total investment for the construction of the Zapolyarye-Purpe pipeline was RUB120bn ($3.7bn), but increased to RUB199bn ($6.15bn), according to September 2013 estimates.
Zapolyarye-Purpe pipeline construction
The Russian Government gave approval to provide finance for the construction of Zapolyarye-Purpe oil pipeline under OJSC Transneft funds in November 2011.
Yuzhno-Russkoye onshore oil and gas condensate field is located about 2,175 miles (3,500km) north-east of Moscow, the capital city of Russia.
The first phase of construction, which began in March 2012, included the section from the town of Tarko-Sale to the town of Purpe. It also involved construction of Purpe oil pumping station at the 358km point.
The first phase of construction also included providing hydraulic testing, profile logging and internal pipe diagnostics on the linear portion of the pipeline.
The second phase of construction began in June 2013 and involved the section from the town of Novozapolyarye to the town of Tarko-Sale. It included construction of 207km of pipeline from kilometre 358 to pumping station number two, as well as expansion of the Purpe pumping station tank farm to a total capacity of 200,000m³.
The third and final phase of construction began in November 2013 and took roughly three years to complete. It involved construction of a 152km section and the N1 Zaployarye pump station.
Contractors involved
Stroygazconsulting (SGC) was awarded three construction contracts, including Purpe oil pumping station transport line, production supply store and central repair depot construction in the village of Korotchaevo, as well as the construction of linear parts from oil pumping station number two to kilometre 358 in March 2013.
HMS Group was awarded a $47m-worth contract to provide eight trunk pipeline pump units for the two pump stations in July 2013. The contractual scope also included production, testing and delivery of trunk pipeline pump units and booster pumps units, delivery of spare parts, and assembling and commissioning on the site.
SGC was further contracted in May 2014 to provide construction services for the third stage of the pipeline project, including construction of the linear part from the head oil pumping station, number one to oil pumping station number two, and between sections 87.50km and 151.49km.
