The stochastic process of container loading is described in the paper with special emphasis to ship motion when she is lying at a quay. The 3 DOF system was applied to describe rolling, pitching and heaving of a vessel which may cause a significant variations of momentary deck elevation. The realistic range of such variations are assessed for a variety of cargo locations on-board and a phase shift between two independent gantries engaged in cargo operations. The process is modeled with regard to random character of crucial variables affecting ship motion due to cargo loading.
In this article the attempt has been made to construct hierarchical model of container ports throughput development. The presented hierarchical approach uses the relationships of development of global economy and container flows at different geographical levels: global (container throughput in all seaport on the world), regional (container throughput in the Baltic seaports) and national (container throughput in Polish seaports). Model have been evaluated for their fit and usefulness for predictive purposes.

This paper investigates vessel traffic risks that are exposed by a new port installation. A vessel traffic risk analysis was performed by the Ship Handling Simulator team for container terminal installation in Izmit Bay. The main purpose is to evaluate whether the container terminal project shall affect the proper operation of nearside Oil Refinery Terminal. Construction and revision of shore structures may form significant threats for masters in ports and narrow waterways. The Ship handling simulator of ITUMF presents the environmental objects’ effects, vessel traffic and weather conditions. Furthermore, the Environmental Stress Model of Inoue (2000) may give an opportunity to analyse vessel traffic risks quantitatively by SHS.
