Zapolyarye-Purpe Oil Pipeline, Russia

The 488km (303mi)-long Zapolyarye-Purpe oil pipeline construction in the Yamalo-Nenetsk region in Eastern Siberia commenced in March 2010. The pipeline is intended to transport around 45 million tonnes of oil in a year, upon the completion of construction by the end of 2016.


The new pipeline will link the untapped oil deposits located in Arctic Siberia to the main pipeline grid, and will also connect fields on the Yamal Peninsula to the Eastern Siberia-Pacific Ocean pipeline (ESPO). The pipeline will be operated by OAO AK Transneft.


The pipeline is being 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 estimated investment for the construction of the Zapolyarye-Purpe pipeline is 120 billion rubles ($3.9bn).


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. The project includes construction of around 1,200km of supply lines in three phases.


The first phase of construction, which began in March 2012, involves the section from the town of Tarko-Sale to the town of Purpe. Construction has already been completed on 129km of trunk line, with a diameter of 1,020mm. It also involves construction of Purpe oil pumping station at the 358-km point.


The first phase of construction also includes providing hydraulic testing, profile logging and internal pipe diagnostics on the linear portion of the pipeline. The construction of a high-voltage line along the pipeline and the linear section facilities for power supply and pre-commissioning works are expected to be completed by the end of 2014.


The second phase of construction began in June 2013 and involves the section from the town of Novozapolyarye to the town of Tarko-Sale. It includes 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 is scheduled to be completed by the end of 2016. It involves 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 includes 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 that includes 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.
