Due to the rapid growth of liquefied natural gas (LNG) consumption, the issues of its transportation and storage are becoming increasingly important. LNG transportation through pipelines attracts the greatest attention of researchers, as it is associated with a number of problems, such as prevention of two-phase flow along the entire length of the pipeline, initial filling and cooling of the pipe, selection of pipeline material that provides the necessary margin of strength and stability, proper choice of insulation coating, etc. This paper analyzes possible solutions to these problems, describes different types of pipeline materials, and proposes the use of polymers as a pipeline material for LNG transport at low subzero temperatures. A consistent methodology for hydraulic calculation of LNG pipeline is proposed. To date, large volumes of LNG have been stored in isothermal storage facilities. The design of LNG storage systems must take into account a large number of factors, such as terrain, geology, meteorology, special environmental and safety requirements, etc. The design of LNG storage systems must be based on a number of factors. This paper discusses the main types of tank designs used, as well as the materials used for their construction. In addition, a method of underground storage is proposed, which consists in constructing a storage facility in the rock strata using a shaftless method. The soils in the conditions of the far north at a certain depth are always in permafrost condition and have bearing capacity, which allows under certain conditions to construct tanks of large volumes with the lowest metal costs. Thermosiphons are proposed to provide cooling. Conclusions are made about advantages and disadvantages of the proposed technical solutions.
