Opis:: The authors present the method of assessing the percentage of coverage of surface of the river by ice occurrences. This article concentrates on image analysis methods applied to assess the percentage of coverage of a waterway by ice occurrences. A decision, whether to stop navigation depends on an accurate calculation of amounts of ice floe and overall atmospheric conditions. For this purpose closed-circuit video camera images converted with the use of a set of edge detecting filters and subjected to quantitative analysis have been used. The correct assessment of ice occurrences may positively influence the navigation itself, as well as help in planning the use of inland waterways in transportation process.

Opis:: Increasing maritime traffic, combined with the possible warming of the climate, will affect the demand for icebreaking assistance. Accurately predicting the local demand for assistance without an appropriate simulation tool is hard because of the number of variables that must be considered. This report describes a simulation tool built around a deterministic, ice-breaker movement computer model. The tool is still under development, and has not yet been tested with real data. However, preliminary test results based on selfgenerated input data are promising.

Opis:: During winter in arctic seas, navigation of ships near ports occurs within ice channels created and maintained by icebreakers. Small ice floes fill the relatively narrow navigable channel, and ships are forced to produce the overtaking or opposing separation over short distances and under the action of ice floes. This paper presents an analytical model of the interaction of ships under the conditions just described as well as the results of a simulation. The simulation showed side force and yawing moments were dependent on ice conditions and the ship’s dimensions and motion characteristics.
