The port areas are specific in terms of navigational accidents. Usually, accidents with low consequences dominate, but due to many users with contradictory needs, there is a requirement to keep the balance between business and safety. This balance is usually achieved by the Port Authority or like in Poland by Maritime Office together with Port Authority. Maritime Offices are the governmental body responsible to maintain the acceptable navigational safety level. Such an approach leads to several frictions between the users that needs are often contradictory. To ensure minimal safety level and introduce new or amended port regulations the scientific methods are demanded to support this process. The paper present methodology to adjust the port regulations of Kołobrzeg Port where the passenger ship owners moored in close vicinity of the waterway and therefore restricted it to the other users. The compromise was achieved with the application of real-time simulation method. Moreover, the paper presents the important role of harbor regulations in whole navigation risk management process within the port area. Today’s port regulations are created mostly based on good practice of pilots and experts, whereas the quantitative methods are used less frequently. The intention of the presented case study was to demonstrate how the quantitative risk assessment could be used in port policy development.

Świnoujście is a Polish seaport located on the Pomeranian Bay, on the southern coast of the Baltic Sea island of Usedom and Wolin. The port is situated in the Świna Strait in Świnoujście, Western Pomerania. The harbor consists of a cargo handling quay, passenger terminal and marina. The seaports of Świnoujście and Szczecin are closely linked economically to form a team and are connected by a passage through the Szczecin Lagoon. All big ships directed to Szczecin have to be routed through the port of Świnoujcie. The hydro-meteorological conditions in the Świnoujście Port area and surroundings, affecting safe maneuvering of ships, are analyzed by statistical methods. The conditions studied, with the aid of Port Captain logbook, are: currents, winds, water level, ice conditions and visibility. The statistical distribution of water level was analyzed and proposed as decision-making tool during a ship’s approach to Świnoujście Port.

W artykule przedstawiono badania związane z optymalną alokacją środków do zwalczania rozlewów olejowych na morzu. Należą one do problemu logistycznego typu lokacja-alokacja (LA). W badaniach skoncentrowano się na statkach posiadanych przez polskie służby odpowiedzialne za rozlewy na Morzu Bałtyckim w tym SAR. Do optymalnej alokacji środków wykorzystano metodę dwustopniową, w której pierwszy stopień, wykonany za pomocą metod optymalizacji genetycznej, polegał na takim rozlokowaniu sił do zwalczania rozlewów, aby zminimalizować koszty dotarcia do rozlewu na morzu. W drugim etapie wykorzystano model symulacyjny rozlewu olejowego i akcji jego zwalczania do weryfikacji rozwiązań uzyskanych za pomocą algorytmu genetycznego.

Wzrost wydobycia złóż ropy z dna morskiego niesie ze sobą ryzyko zwiększenia się prawdopodobieństwa wystąpienia rozlewu olejowego nie tylko w rejonie eksploatowanych złóż, ale również na trasach uczęszczanych przez statki transportujące ropę naftową i jej produkty. Niniejsze opracowanie porusza tematykę prowadzenia akcji poszukiwania rozbitków przy jednoczesnym wystąpieniu rozlewu produktu ropopochodnego a w związku z tym zagrożeń związanych z przebywaniem zarówno rozbitków jak i ratowników w środowisku toksycznym dla człowieka. Zagrożenia związane z obecnością produktów ropopochodnych na miejscu akcji to między innymi ich łatwopalność, tworzenie się par wybuchowych w powietrzu, obniżenie zawartości tlenu w atmosferze i toksyczność produktu. Artykuł rozważa również wpływ rozlewu olejowego na możliwości lokalizacji rozbitków.
