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.

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.
