The urgency of developing technologies for liquefying natural gas is substantiated. The analysis of world and domestic experience in this field is performed. The urgency of development of highly effective technologies for liquefying natural gas is substantiated.It is shown that plants on floating platforms are the preferred alternative to LNG plants located on land. Their decisive advantages are the absence of the need for large land resources and the possibility of building in the factory at shipbuilding enterprises. It is shown that the location of LNG plants in the open sea and, accordingly, the shipment from them to gas carriers requires additional technical measures in comparison with the location of the plant in the coastal, as a rule, closed from the excitement zone. Proposals for the creation of floating plants for obtaining LNG in relation to the Arctic are formulated. Parameters of modern floating plants for liquefying natural gas are given. Separate questions of LNG transport are considered and their analysis is carried out, which made it possible to identify the features of the use of LNG marine and pipeline transport. The analysis of the development of various types of storage tanks of LNG on the basis of which the advantage of isothermal capacities was revealed. The problems of storing LNG in isothermal storage facilities, as well as the peculiarities of occurrence of emergency modes in them as a result of injecting without mixing the new LNG into an already partially filled reservoir (LNG stratification or “rollover”) were investigated.
