  • Comparative assessment of options for the transportation of hydrocarbons in the development of fields on the shelf of the northern seas

    The choice of a method for transporting hydrocarbons from the shelf of the northern seas is an urgent task, necessary for the economic justification of a project for the development of an offshore field. A comparative analysis of existing transportation schemes allows us to take into account both the advantages and disadvantages of possible options, namely, the natural and climatic features of the region, the technical capabilities of contractor organizations, the cost of field development facilities and vehicle rental.

  • Analysis of underground oil and gas pipelines construction technologies in seismically hazardous areas

    Ensuring the reliability of oil and gas pipelines laid in zones with increased seismicity, namely, the choice of design and technology for the construction of pipelines, is a topic of current and requiring serious study. The article considers methods of laying underground pipeline in seismic areas, provides analysis of proposed structures and construction technologies. To minimize the identified shortcomings, the authors proposed a structural diagram of a pipeline built by the microtonneling method, which will ensure the stability of the structure to seismic loads and reduce construction and operation costs.
