This article explores the significance of future prospects for the development of maritime transportation of natural gas, which is one of the main sources of energy raw materials. Transportation of gas on sea vessels is expedient and cost-effective only in liquefied form, when the volume of natural gas is reduced by more than 600 times. Liquefied natural gas (LNG or LNG) carriers are called LNG carriers. The purpose of the study is to develop a new mathematical model that will play the role of a methodological basis for forecasting changes in the global volume of LNG shipping. In the course of the study, general scientific methods of system analysis and synthesis, methods of mathematical statistics were used. The article presents the results of the study of trends in the global maritime LNG transportation market development. The author considers the main exporters and importers of LNG, as well as an assessment of the growth in its demand after the decline of the COVID-19 pandemic. The trend in the development of innovative gas liquefaction production capacities, as well as the state of the world LNG fleet and the dynamics of its increase, are analyzed.The development research of this area of maritime transportation has been carried out and the dynamics of the increase in the volume of transported LNG in recent years has been analyzed.
