Abstract

The gradual shift of the Russian Federation oil production center to the areas with difficult climatic conditions, states additional challenges to the Oil production companies during development of these regions. Impossibility of underground design of oil pipelines in waterlogged areas, areas with subsurface voids unstable of different origin, permafrost zones, landslide zone forces companies to focus laying pipelines by above ground manner. The purpose of this article is to present a review of the stress-deformed state of the aboveground pipeline, its behavior during operation and pressure test stage, the forces acting on the pipeline. The study allows us to understand the state of the pipeline, to assess its stability and reliability. Analyzing the research results, it must be concluded that the decision of choice the above ground pipeline design (route geometric parameters), should be performed, guided not only meet the conditions of strength, as well as other reasonable important factors: the values ​​of the forces acting on the fixed supports, three-dimensional position of the pipeline during hydraulic testing and operation, vibration in the pipeline, the impact of ambient temperature, wind resistance aboveground pipeline, further arising forces affecting piping supports, due to thawing of ground and soil bulging, etc.
