Functional model of river-sea ships operating in European system of transport corridors: Part I. Methods used to elaborate functional models of river-sea ships operating in European system of transport corridors
This paper presents a functional model of river-sea ships (shortly called: SRM) operating in European system of transport corridors. It is composed of two parts: Part I contains a descriptive model of functioning the SRM fleet with taking into account various shipping tasks as well as impact factors (external and internal factors, limitations and criteria). Also, a mathematical model of functioning the SRM fleet, including choice of relevant economic criteria (e.g. profit maximization, capital return period minimization etc), is presented. Results achieved on the basis of the functional model are presented in Part II of the paper.
Functional model of river-sea ships operating in European system of transport corridors: Part II. Methods of determination of design assumptions for river-sea ships operating in European system of transport corridors, according to their functional model
This paper presents continuation of the research on the functional model of river-sea ships operating in European system of transport corridors. It deals with a set of methods of determination of design assumptions for river-sea ships. Relevant calculations were performed on the basis of a future network of European routes for operating the river-sea ships within EU system of water transport corridors, in which rates of cargo flows and lengths of particular routes as well as their mathematical model were taken into account. In consequence, technical assumptions for designing the fleet of river-sea ships to be operated in European system of water transport corridors, were obtained.
This paper presents the methodology of strength verification during load out of the heavy cargo, in this case Arkutun Dagi SE-Topside platform. General methodology of making calculation models and load algorithms has been presented. Paper shows results of verification of global shear forces and bending moments using self-developed algorithms to modify centre of gravity, fill tanks and hydrostatically balance a 3D finite element model with commercial hydrostatic code. The NAPA and ANSYS codes were used to calculate hydrostatic pressures and to apply to 3D-FE models and to carry out strength calculation of barge construction.
This article concerns safety during ship docking operations. It presents its specificity for this type of operation, describes selected problems that may occur during its operation and identifies the main factors initiating extraordinary situations. The article presents 4 examples of accidents during docking operations in recent years. Cause and effect analysis was carried out and presented graphically. This analysis illustrated the occurring errors in the safety system during the docking operation.
The article concerns the problem of inland waterways transport of LNG. Its aim is to present the algorithm of conceptual design of inland barges for LNG transport, intended for exploitation on European waterways. The article describes the areas where LNG barges exist, depending on the allowable operating parameters on the waterways. It presents existing architectural and construction solutions of barges for inland LNG transport, as well as the necessary equipment, due to the nature of cargo. Then the article presents the procedure of the conceptual design of LNG barges, including navigation restrictions and functional and economic criteria. The conceptual design algorithm of LGN barges, presented in the article, allows to preliminary design calculations, on the basis of which, are obtained the main dimensions and parameters of unit, depending on the transport task and the class of inland waterways, on which the transport will be realized.
This article presents the concepts of inland passenger transport: tourist and cruise in the basin of the Oder river. The first part describes the operating and technical parameters of the Oder and the present trends and directions in the development of inland waterway passenger services. Another part of the article contains an analysis of the results of the surveys carried out among respondents living in agglomerations lying on the Oder River. These studies have enabled the creation of two passenger transport concepts that enhance the competitiveness and attractiveness of inland waterway transport with respect to other modes of transport.
