“…The development of a competitive environment between individual sectors of the transport system necessitates the development and implementation of solutions aimed at maintaining the leading position of railway transport in the segment of total freight turnover [1][2][3]. One of the possible solutions to achieve this goal is the introduction of combined transport systems, in particular container systems, as the most common and highly demanded for international traffic [4,5].…”

The article presents the results of the study into the dynamic load of the container during its transportation by the train ferry. The peculiarity of the container is that its walls are made of sandwich panels. Such a solution will help to reduce the dynamic loads acting on the container at operating load modes, including when transported by sea as part of combined trains. To determine the dynamic loads acting on the container, a mathematical model was build that took into account the angular displacements around the longitudinal axis of the system "train ferry -flat wagon -containerfreight". The calculations were made for the train ferry Geroi Plevny. The mathematical model was solved in MathCad. It was found that the value of acceleration acting on the container of the proposed design during transportation by sea was 4.3% lower than that acting on the container of a typical design. The acceleration value obtained, as a component of the dynamic load, was taken into account to determine the stability coefficient of the container in a typical diagram of its interaction with the flat wagon. The roll angle of the train ferry, at which the stability of the container placed on the flat wagon is ensured, was also calculated. The results of the study will contribute to the database of recommendations for the design of modern container structures and their safe operation in international rail and water traffic.

Although optimization of Vessel Turnaround Time (VTT) is a well-known research problem and its importance has long been understood, research on dry bulk carriers VTT has no priority in the available literature. It is one of the initial motives of the author to write this paper. After a general theoretical introduction, this paper presents research on dry bulk carriers’ loading time, as a component with the dominant share in the total VTT. Through the research, a mathematical model of interdependencies between dry bulk carrier‘s loading time and selected independent variables is defined using a multiple linear regression model. Results of statistical significance tests confirmed that the best-fit regression model is the one which adequately describes the correlation between the dry bulk carrier‘s loading time and the following independent variables: cargo quantity (loaded), number of used cranes per vessel and loading process interruptions. The presented results establish important bases for the author’s further research in this field as well as reliable planning bases for cargo handling management processes at dry bulk cargo terminals where cargo loading/unloading to/from vessels is realized by gantry cranes and/or mobile harbour cranes.
