The article presents an exemplary application of the multi-criteria navigational safety assessment method for the proposed variants of the designed waterway in order to verify it. This method comprehensively considers the most important environmental and technical aspects related to the implementation of the planned investment. The method can be used for the purposes of navigational analysis, i.e. an engineering document that meets the requirements of the regulation of the competent, which subject to agreement with the Director of the territorially competent Maritime Office.

The necessity of verifying manoeuvring mathematical models in shallow water for studying the safety of ships using a ship-handling simulator is pointed out in this report. Several instances of verification of mathematical models in shallow water are introduced here based on measurements of motion conditions of full-scale ships and shallow water tank tests of models. Results of safety assessment tests of five manoeuvring phases are given using the verified manoeuvring mathematical models to discuss manoeuvring criteria in shallow water. Objective manoeuvring criteria for safety assessment in shallow water are proposed based on subjective judgement related to control margin assessed by more than 3,200 masters and pilots for over 325 simulation tests and by analysis of the study results of 15 full-scale ships.

A ship domain is nowadays an important navigational safety assessment criterion. Its shape and size depend on many factors. The available maneuvering area seems to be one of the most important of them. This article examines the influence of the available manoeuvring area on the shape and size of ship domain in the open sea and restricted waters. The research was conducted using a simulation method. Expert navigators participated in simulations using the ECDIS system. The domains of ship passages in open sea area and restricted area have been compared.

The ship domain is one of the criteria for navigational safety assessment. It is particularly important in restricted areas with high intensity traffic, where the criteria of closest point of approach (CPA) and time to CPA are difficult to apply. This research continues to examine ship domains in Traffic Separation Schemes (TSS). We have analyzed precautionary areas established within TSSs in connection with changed arrangements of vessel traffic. Besides, we have defined ship domains in a precautionary area of a specific TSS, and compared them to domains of vessels proceeding along traffic lanes.

The paper presents the assumptions of a simulation model for assessing the navigational safety of fishing vessels. The model consist of submodels of merchant and fishing vessels traffic, submodel of external condition and submodel of accident consequences. Paper present also a results of simulation experiment which was carried out for Polish EEZ. Model takes into account all Polish fishing vessels operating in the Polish EEZ with length more than 15 meters and the merchant vessels traffic in South Baltic Sea area. As a results positions of simulated collisions of fishing and merchant vessels, positions and sizes of simulated bunker spills and the positions of losses of fishing equipment were achieved.

W artykule przedstawiono założenia złożonego modelu symulacyjnego dla szacowania bezpieczeństwa nawigacyjnego statków rybackich. Model składa się z modeli ruchu statków handlowych i statków rybackich, modelu warunków środowiskowych oraz modelu skutków zdarzenia. Ponadto w artykule przedstawiono rezultaty eksperymentu symulacyjnego przeprowadzonego dla polskiej wyłącznej strefy ekonomicznej. Model uwzględnia wszystkie polskie statki rybackie operujące w polskiej wyłącznej strefie ekonomicznej o długości większej niż piętnaście metrów oraz ruch statków handlowych na południowej części Morza Bałtyckiego. W rezultacie otrzymano pozycje prawdopodobnych kolizji statków transportowych oraz rybackich, pozycje i rozmiary prawdopodobnych rozlewów olejowych oraz pozycje utraty narzędzi połowowych.
