摘要：International shipping is the source of around 3% of global CO2 emissions. Liquefed natural gas (LNG) is currently considered the only reasonable and commercially advanced alternative to the petroleum-based ship fuels.Liquefed natural gas can make a signifcant contribution to the diversifcation of transport fuels, reducing thegreenhouse gas emissions from ships and heavy vehicles. The introduction of LNG technology as a drive for inlandships is a complex process. It requires activities in various areas, including development, legislation, building infrastructure, construction of new ships or their reconstruction. The greatest problem now seems to be the certaintyof investing in the new fleet or their reconstruction. It is therefore desirable to assure shipowners that the investment in renewing or reconstruction should be guaranteed. This paper provides a study of reconstruction of theinland tugboat (tug) to a dual fuel system (diesel – LNG). A tugboat used by Slovak shipping company was chosenas a model vessel. The results presented a comprehensive design of the main and auxiliary engine remodelling, aswell as the design of the vessel’s tanks and show how the conversion affects the basic navigational characteristicsof the tugboat. Finally, the results point to the conversion methodology which is partly applicable to another typeof inland tug, considering the individual specifcities.
