Before starting to design, the specialists of the Pipeline Transport Institute and the design institute Giprotruboprovod have studied the domestic and foreign experience of such construction. The Pipeline Transport Institute decided to rely on security: the company's specialists, taking into account all the pros and cons, independently developed both support design and other unique engineering solutions. The designers made supports of three types: anchor-type, loose and longitudinal guide. On the one hand, they have securely fixed the pipe, on the other hand, they allowed it to move in the axial and transverse directions, neutralizing temperature stresses.The supports were installed on the piles, immersed in the ground to the depth of 18 meters. At the same time, not to melt the permafrost, heat stabilizers filled with refrigerant were immersed in the ground near the piles. They were also developed by the specialists of the Pipeline Transport Institute and surpassed all the other available samples in capacity.
The first joint of the Polar Circuit - Purpe pipeline was welded on March 5, 2012. The oil pipeline with a total length of 488 km was built from the south to the north, from the end point of the oil pipeline system Purpe to the head station Zapolyarye. The work continued simultaneously at several sites - pipes were being welded, supports were being erected, piles were being driven.
The oil pipeline Zapolyarye – Purpe is capable of pumping up to 45 million tons of oil per year. It will allow to take the raw materials from new deposits of Yamalo-Nenets Autonomous Okrug and the north of Krasnoyarsk Krai into the main trunk pipeline system. These are the Urengoyskoye field ("Gazprom"), the Suzunskoye, Tagulskoye, Russkoye, Russko-Rechenskoye fields ("Rosneft"), the Messoyakhskoye and Vostochno-Messoyakhskoye fields ("Rosneft" and "Gazprom Neft") and the Pyakyakhinskoye field ("LUKOIL").

Zapolyarye – Purpe Oil Pipeline
In October 2010, engineering surveying began on the route of the future pipeline. At the very beginning, the builders saw the main problem they would have to solve: 70% of the route was situated in the permafrost zone, and almost half of it was swamped. Having weighed all the pros and cons, the company's specialists decided to combine the above-ground and subsurface pipelining. More than 300 km of the pipe had to be laid above the ground on supports, and 170 km were to be laid by the usual subsurface method.Before starting to design, the specialists of the Pipeline Transport Institute and the design institute Giprotruboprovod have studied the domestic and foreign experience of such construction.
