RN-Vankor, a Rosneft subsidiary, is finishing the construction of a linear sector of Suzun-Vankor intrafield oil pipeline – the so called ‘golden’ (final) junction of the intrafield pipeline has been welded. Building and installation works had been carried out since December 2014.
The length of the pipeline, which linked Suzun and Vankor fields is 99 km, and the diameter of the pipe is 530 mm. It was laid by ground-based method according to a well-tried technology – basing on supports, which provide pipeline’s reliable service even under conditions of temperature and pressure changes. This method provides for piles driving-in, support mounting and laying pipelines with protective corrosion-resistant and heat- waterproofing coating. The heat-set technology is being used in order to minimize the impacts on the permafrost soil, ensure the reliability and sustainability of oil pipeline.
The technical solutions and technologies, applied during the construction, provide minimal impact on the plant cover and consider animal’s migration paths. During the construction all the environmental protection requirements have been met. Works have been carried out during the winter season.
Launch of the Suzun-Vankor pipeline is synchronized with other objects of first start-up complex in the Suzun field – commissioning of oil wells, building of crude-treatment plant, as well as other facilities of industrial and utility purpose. After welding of the final junction on the linear part of the pipeline, building and installation operations on the establishment of isolation valves’ nodes, oil launching stations and intake of cleaning units, equipment systems to automate and communication installation will be continued.
Currently, works on the construction of an oil preparation unit (UPOG) with annual capacity of 5.2 mln mt, construction of well pads, intrafield pipelines, power lines are being actively carried out at the Suzun field. Operation drilling is performed on five well pads. Commissioning of the field is scheduled for this year.
The oil from the Suzunskoye will be transported via Suzun-Vankor intrafield oil pipeline to the main oil pipeline through a central gathering station of Vankor’s production facility.
Development of Suzunskoye as well as Tagulskoye and Lodocnoye fields, which constitute the Vankor cluster, is carried out using infrastructure that has already been built and is functioning. This development plan has significant synergies, and impetus to foster the related industries and domestic technologies. Today more than 160 enterprises of the region are working on development of Vankor cluster.
