Annual of Navigation
2006 No. 11 103-122
EN This paper discusses the question of classifying the sea areas as sea areas difficult for navigation, unrestricted sea areas and sea areas restricted by land (bottom or shore). Most of all, the article depicts the characteristics of restricted sea areas. It presents the attempt to define in a new wa[...]

EN The identification of areas of collision risk in restricted waters could play an important role in VTS services. Based on the concept of ship domain, this paper introduces a model for identifying collision risk between vessels in restricted waters, then puts forward an improved DBSCAN clustering alg[...]

EN Accurate prediction of the ship squat is of significance to ensure safety passage of ships in restricted waters. In this paper, a first-order Rankine source panel method is adopted to predict the squat of a ship sailing in restricted canal. Taking KVLCC2 tanker as example, numerical calculations are[...]

EN Traditionally, marine traffic congestion degree in restricted waters is usually deduced from traf-fic volume or traffic density. Both of which, however, can not be easily and accurately determined and can not fully reflect the traffic congestion degree. This paper uses the concept of main traffic fl[...]

EN Ship navigation safety in restricted water areas is of great concern to crew members, because ships sailing in close proximity to banks are significantly affected by the so-called ship-bank interaction. The purpose of this paper is to apply the optimal control theory to help helmsmen adjust ships’ c[...]

PL W ostatnich latach przeprowadzone zostały liczne badania mające na celu identyfikacje sił hydrodynamicznych działających na manewrujący statek na akwenach portowych przystosowanych dla dużych statków. Niekorzystne zjawiska, które oddziałują na warunki eksploatacji statku na ograniczonej drodze wodne[...]
EN The problem of ship squat is one among the crucial factors affecting the navigation of ships in restricted waters. The squat can be estimated using either the empirical or analytical models. It may be evaluated by implementing the real scale tests or CFD technology as well. The results of calculati[...]

PL W pracy przedstawiono zakres informacji o manewrowaniu statku morskiego oraz jego stanach eksploatacyjnych w rejonach ograniczonych. Omówiono model ruchu statku oraz różne parametry zakłóceń zewnętrznych działających na statek. Przedstawiono zakres informacji o manewrach statku zalecanych przez Międ[...]
EN This paper relates to manoeuvring information used for passage planning in restricted waters. Different phases of ship movements in terms of external disturbances have been discussed. Required information for passage planning published in the IMO (International Maritime Organization) documents has b[...]

PL Metody oceny ryzyka wypadku statku podczas manewrów na akwenie ograniczonym opierają się głównie na obliczeniach danych statystycznych dla poszczególnych portów i w zależności od osiągalności takich danych są mniej lub bardziej dokładne. W artykule zaproponowano podjęcie rozważań dotyczących wpływu [...]
EN The methods allowing risk assessment of ship accident in restricted waters are mostly based on statistical calculations for particular ports depending on availability of the limited statistical information from past. Model proposed by Maritime Academy in Szczecin is more comprehensive and universal,[...]

EN 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 shi[...]

EN In this paper the author depicts new approach involving fuzziness in navigational situation assessment. Nowadays operator at maritime traffic monitoring station is assumed to have access to a great amount of data. The data comes from different places and multiple of sensors. Properly associated data[...]
