Strong expansion of cruise ships traffic and cruising destinations in the Adriatic makes the region ideal for cruise ships routing analysis. The aim of this paper is to detect real cruise ships traffic movement in order to understand how present cruise ships routes are navigationally and environmentally sustainable and safe. Cruise ships characteristic operational demand and navigational routine in relation with regions indented coast line with high level of environmentally preserved areas in landscape of high national value, emphasise importance of real cruise ships routing awareness. The research is based on one year cruise ships traffic monitoring and routes analysis in the Central Adriatic East coast. The results offer detail insight of cruise ships navigational routines in navigationally less defined area that has not been frequent cruising region before. Cruise ships routes comparison is carried out between North Adriatic region, which is well defined with traffic separation schemes and navigational aids and less defined Central and South Adriatic regions. The results show that principle of cruise ships routing differ from standard maritime practice and that operational demand for attractive cruising and passenger experience bring cruise ships close to shores in various demanding navigational situations. That routing practice does not meet criteria of sustainability as it often present high navigational, safety and environmental risk.

The article presents an original two-stage simulation method for the optimization of seaport parameters. Presentation of the method is based on example of parameter optimization of the outer container port in Świnoujście. Presented method uses two limitations of the objective function related to safety of manoeuvring and mooring of ships. It consist of two stages, first one is carried out for the parameters defined in the preliminary stage of design. On the basis of results from this stage, layout and other parameters of port waterways can be adjusted to satisfy assumed safety criteria. The second stage uses the parameters established in the first stage. It allows for small adjustments which will not change the safety of manoeuvring. The result of second stage is optimal parameters of the examined port waterways.

The paper presents methods and models used for analysis of ships traffic in north of Bornholm Traffic Separation Scheme. Ships' traffic has been analyzed by means of statistical methods with use of data possessed from AIS data obtained from HELCOM. The paper presents probabilistic models of ships' traffic spatial distribution and its parameters. The results could be used for safety and risk analysis models in given area and for creation of general models of ships' traffic flows.

W artykule przedstawiono metody i modele stosowane do analizy strumieni ruchu statków w strefie separacyjnej na północ od Bornholmu. Ruch statków został przeanalizowany metodami statystycznymi z użyciem danych pozyskanych za pomocą systemu AIS otrzymanych z sieci HELCOM. W artykule przedstawiono probabilistyczne modele rozkładu horyzontalnego strumienia ruchu statków i jego parametry. Wyniki tego opracowania mogą zostać wykorzystane do budowy ogólnych modeli rozkładów ruchu statków.

Using the concept of a ship’s domain at a waterway intersection, the ships’ traffic equations were determined, describing a situation where they pass each other at the intersection without collision. A field of limit velocity vectors was established, at which the vessel can pass through the intersection without collision. On the basis of designated vector fields, the control area of entry of the subordinated vessel into the intersection was defined.
