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 shippingtasks as well as impact factors (external and internal factors, limitations and criteria). Also, a mathematical model of functioning the SRM fleet, including choice of relevanteconomic criteria (e.g. profit maximization, capital return period minimization etc), ispresented. Results achieved on the basis of the functional model are presented in Part II of the paper

Water tourism is a key element in development of not only coastal regions. Activities witch stimulate different forms of tourism should be therefore kept including yachting, witch unfolds very dynamically lately. The article shows role and meaning of yachting in polish water tourism and maritime and inland economy development. The author presents the structure of tourist movement in the last years, describes yachting forms and makes assessment of yachting and its influence on tourist sector.
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
