The thesis explained and analyzed the turbine propulsion systems on ships for the transport of liquefied natural gas LNG and liquefied petroleum gases LPG. The historical development of built-in drive systems and the effect they had on the economy as well as shipowners, who are regularly subject to increasingly strict measures for energy efficiency, are listed. Trends in the development of turbine systems are given. The most common problems regarding the maintenance of turbine systems and their typical failures are considered. The technology of LNG ships and their propulsion turbine systems has also been elaborated in detail, and possible improvements that were not known to engineers at the beginning of production have been proposed. Calculation of losses of turbine drive systems was performed and a comparison was made with other drive systems. Innovations on the market, which are the result of people's desire for constant improvement and preservation of ecology, have led to the development of drive systems that work on alternative fuels, and thus to gas turbines that have found a source of energy in them.
