Opis:
Increasing transport volumes on Europe's inland waterways is a major reason for improving the quality and reliability of internationally important waterways. Continued navigation restrictions due to restricted draft (draught) led to the search for new design solutions. Such solutions enable navigation even under critical navigation conditions. Restricted draft is one of the most important limitations that hinder navigation, especially in the summer. The main objective of the construction of an inland vessel is to obtain a shape that will achieve optimum performance with as little resistance as possible. A shape that will be able to navigate at a limited depth. Presently, there is no clearly defined methodology as a procedure for optimising the hull. When solving theoretical problems of shipbuilding character and ship calculations, it is necessary to consider the basic theory of the ship with special regard to the latest methodological procedures of related scientific disciplines. This paper presents a methodology that considers all the basic aspects of optimisation tasks in ship design and construction.

Opis:
International shipping is the source of around 3% of global CO2 emissions. Liquefied natural gas (LNG) is currently considered the only reasonable and commercially advanced alternative to the petroleum-based ship fuels. Liquefied natural gas can make a significant contribution to the diversification of transport fuels, reducing the greenhouse gas emissions from ships and heavy vehicles. The introduction of LNG technology as a drive for inland ships 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 certainty of 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 the inland tugboat (tug) to a dual fuel system (diesel – LNG). A tugboat used by Slovak shipping company was chosen as a model vessel. The results presented a comprehensive design of the main and auxiliary engine remodelling, as well as the design of the vessel’s tanks and show how the conversion affects the basic navigational characteristics of the tugboat. Finally, the results point to the conversion methodology which is partly applicable to another type of inland tug, considering the individual specificities.
