The paper analyses the propulsion systems of inland waterway vessels according to the criteria of economic efficiency, ecology and safety. The professional experience of the authors and their expert knowledge indicate that always the increase of safety level as well as ecological solutions are realized at the expense of economic efficiency. Therefore, arguing for the result of such analysis, the features of water bodies, port infrastructure and elements which should influence the selection of propulsion systems, features of various types of power and fuels with their energy value guaranteeing the swimming range were described. Types of propulsion systems were characterized and a model of selection of propulsion system to the type of sailing was presented. The analysis presented in the article is necessary for a reliable assessment of the accuracy of the selection of the propulsion system for the actual conditions of operation of sea and inland waterway vessels, i.e. for the type of the vessel and its suitability to perform operational tasks on specific waterways.

W artykule dokonano analizy napędów śródlądowych jednostek pływających we-dług kryteriów efektywności, ekologii i bezpieczeństwa. Doświadczenie zawodowe autorów i ich wiedza ekspercka wskazują, że zawsze wzrost poziomu bezpieczeństwa jak i rozwiązania ekologiczne realizowane są kosztem efektywności. Dlatego też, argumentując wynik takiej analizy opisano cechy akwenów, infrastruktury portowej oraz elementy, które powinny mieć wpływ na dobór napędów, cechy energii zasilającej i paliw z ich wartością energetyczną gwarantującą zasięg pływania. Scharakteryzowano typy napędów oraz przedstawiono model doboru napędu do typu żeglugi. Analiza przed-stawiona w artykule jest niezbędna do rzetelnej oceny trafności doboru napędu do rzeczywistych warunków eksploatacji jednostek pływających, czyli do typu jednostki oraz jej zdatności do wykonania zadań eksploatacyjnych na określonych akwenach.

This article contains a description and analysis of the hypothetical application of the inland barge as an "aircraft carrier" with observation aircraft, both manned helicopters and unmanned drones. The equipment of the barge would include the infrastructure of aircraft servicing, storage and social space. This is the first presentation of such an idea in Polish literature and a continuation of previous researches on drones by the same author.

Artykuł dotyczy problematyki ograniczania emisji substancji gazowych i pyłowych na statkach śródlądowych w związku z nowymi uregulowaniami prawnymi i technicznymi obowiązującymi na obszarze Unii Europejskiej. Jednym z kierunków spełnienia norm ochrony środowiska, w tym normy STAGE V, jest stosowanie paliw alternatywnych w napędach nowo budowanych statków śródlądowych lub stosowania instalacji ograniczających emisje szkodliwych substancji do atmosfery na statkach będących w eksploatacji kilkadziesiąt lat. Celem artykułu jest analiza wybranych rozwiązań napędowych i możliwości ich wdrożenia w najbliższych latach, aby dostosować tabor pływający do nowoczesnych wymagań technicznych oraz obniżyć ich koszty eksploatacji. W artykule przedstawiono dotychczas stosowane rodzaje napędów na jednostkach śródlądowych oraz uwarunkowania prawne określające warunki wdrażania paliw alternatywnych i stosowania technologii ograniczających emisje spalin. Przeanalizowano wybrane paliwa alternatywne oraz możliwości ich zastosowania w napędach statków śródlądowych. W ostatniej części rozpatrzono aspekt ekonomiczny zastosowania gazu naturalnego jako paliwa i jego wpływ na korzyści armatora statku śródlądowego.

The authors of the article raise the issue of limiting the emission of gaseous and dust substances on inland vessels in connection with new legal and technical regulations in European Union. One of the directions of meeting environmental protection standards, including STAGE V, is the use of alternative fuels in drives of newly built inland vessels or the use of installations limiting emissions of harmful substances to the atmosphere on vessels in operation for several decades. The aim of the article is to analyze selected drive solutions and the possibilities of their implementation in the coming years to adapt the fleet to the modern technical requirements and reduce their operating costs. The article presents hitherto used types of drives on inland units and legal conditions defining for the implementation of alternative fuels and the use of technologies limiting exhaust emissions. In addition, were analyzed selected alternative fuels and options for their use in inland waterway vessels. The last part deals with the economic aspect of the use of natural gas as a fuel and its impact on the benefits of the owner of an inland vessel.

In the present paper presented are the results of prediction of total resistance of inland waterway vessels based on model test data. In scaling the resistance from model to full scale the extrapolation with two-dimensional frictional resistance formulation (without form factor) was applied, combined with different methods of determination of frictional (viscous) resistance coefficient. There were used the equations that include the effect of water depth, with and without account for pressure gradient. It was shown that limited depth of water substantially affects the frictional resistance. The results of example calculations are compared to resistance prediction made using the ITTC 1957 modelship correlation line. Example calculations take into account the limited depth of water. Depending on the applied method of determination of frictional resistance coefficient the resultant total resistance of inland waterway vessel is higher or lower than the resistance based on the ITTC 1957 correlation line. The effect of water depth depends on the ratio of water depth to ship draught (h/T), on ship speed, and on the composition of a convoy. The extrapolation of resistance was made without including the form factor. Computations are made based on model test data for an inland waterway cargo vessel, for a kombi-type convoy of an inland waterway cargo vessel and a dumb barge, and for a convoy of two dumb barges without a pushboat.

Data from model tests of an inland waterway vessel in shallow water have been used by the authors to prepare the resistance prediction in full scale. The common ITTC-1978 extrapolation procedure was applied using form factor determined according to the Prohaska method and, separately, by fitting the approximation function to resistance data. At the same time a series of CFD computations of ship flow has been carried out in model scale and in full scale, with double-body model as well as including the effect of free surface. The results of computations were used to determine total resistance and form factor. The values of form factor determined using different methods are similar and relatively high in comparison to values being applied to conventional sea going ships. Resistance prediction according to the ITTC-1978 with form factor was compared to prediction without form factor. The relative difference of resistance amounts 28% at ship speed of 10 km/h and 24% at ship speed of 12 km/h.

Flow around an inland waterway vessel in shallow water was computed in model scale using CFD software Fluent. Theoretical data were compared to the results of measurements in towing tank. The comparison comprises ship resistance, wave profile on hull surface, and distribution of velocity in tlow around bow and stern.

Przy użyciu programu komputerowego Fluent obliczany był przepływ wokół kadłuba statku śródlądowego w skali modelu. Wyniki obliczeń zostały porównane z wynikami pomiarów w basenie holowniczym. Porównanie obejmuje opór kadłuba, profil fali na powierzchni kadłuba i rozkład prędkości przepływu w pobliżu dziobu i rufy.
