    The specificity of navigation in the Baltic Sea means that intensive ship traffic occurs on the main shipping routes. Therefore, there is a high risk of a collision that will result in an oil spillage; the Baltic Sea is an area that is very sensitive to this type of accident. In addition, there are sensitive Natura 2000 areas that require special protection. A case study of a potential oil spill in the Słupska Bank area has been carried out in this paper; the results of the oil spill simulations and their analyses are presented in this article. The simulations were carried out in the PISCES II oil spill simulator. The spread of oil pollutants in typical weather conditions, the size of the threatened areas and the oil’s impact time have been analyzed. Based on the results obtained from the simulations, the most adverse weather conditions for the simulated oil pollution accident in the TSS Słupska Bank region have been determined.

    The risk analysis of ships’ accidents leads to the conclusion that one of the most important and dangerous stages existing during a ship’s trip is harbour entering and leaving. The use of the modern methods of risk estimation should improve both ship/harbour safety and the economic profitability of the taken decisions. This concerns especially the harbour entering by maximum acceptable size ships for the given harbour. The analysis of the indispensable data sets and the decision model algorithm proposed for the system of Szczecin– Świnoujście ports were described in the article. The use of the decision model, taking into consideration the dynamic current data and hydro-meteorological conditions, including their changes tendency and the possible changes of ship movement parameters, should increase the decision efficiency and hold the same safety level

    Natural gas, being the cleanest burning fossil fuel, will play a key role in the future. Liquefying natural gas lets moving it to regions where pipeline transport is not possible, allowing end-use markets access to natural gas. LNG is more energy dense than gaseous natural gas, so there using fields are still increasing in end-use applications, e.g. different types of transportation (heavy duty vehicles, marine or rail applications). Global LNG demand is expected to grow, mostly because of new economic markets from Asia and Middle East

    One of the most important factors of the tracked target movement estimation accu-racy is precise information on own ship’s true course and speed. If this information is incorrect due to constant error, the computed true course and speed of the tracked target could be false. The research herein presented has dealt with the estimation accu-racy in the case when the information on true speed of own ship is false.

    Closest point of approach (CPA) is a basic factor taken into consideration for risk assessment during the meeting of two ships at sea. Navigators should use radars with automatic target tracking for collision avoidance and should know the accuracy to which radar data are calculated. Basic information about these requirements can be found in IMO resolutions. The currently binding document for devices manufactured after 2008 is IMO Resolution MSC.192(79). But there are two independent requirements for relative motion. One of these refers to relative motion parameters (relative course and speed) and the other one to the value that is the result of this motion (CPA). The other important document is Standard 62388. This specifies the minimum operational and performance requirements, methods of testing and the required test results published by IEC and also refers to radar equipment. However, this standard is not so popular in different publications focusing on radar equipment, so these requirements were not analyzed in the article. The main problem described in this paper refers to the mutual consistency of IMO Resolution requirements. The results of simulations and their analysis are presented.

    Computer simulations used for predicting the behavior of oil spills at sea allow optimizing the deployment of oil spill response personnel and resources, and using the backtracking method to identify the polluter in cases where spills are sighted some time after they occurred. Predicting the direction and speed of oil slick spreading is of fundamental importance. An attempt was made to verify the influence of selected simulation parameters, related to hydrometeorological conditions, on the behavior of the resulting oil pollution. Different responses were obtained under the same simulated weather conditions, depending on the type of spilled oil. The experiment was conducted on a PISCES II oil spill simulator.

    One consideration required in the resolution concerning radar and automatic radar plotting aid (ARPA) equipment is the possibility of an automatic drift calculation being realized in the base of fixed target tracking. This information is very important to providing safe navigation, especially in restricted areas. This paper presents an analysis of the present regulations contained in IMO resolutions and the results of an experiment conducted in the ARPA simulator. The aim of the simulations was to verify the reliability of the information presented on the ARPA display and to determine the accuracy of the automatic drift calculation implemented in the simulator.

    A key element in ensuring the safety of the port of Świnoujście against oil spills is to ensure combat units are properly equipped with oil spill collecting equipment, and that they have the ability to effectively use the existing resources. All of this should be properly reflected in the port’s contingency plans. It is also important to develop tactics for oil spill combat action that take into account both local conditions and worst case scenarios with parallel checking of these scenarios during the exercise and the table-top exercises. The use of computer simulation to forecast oil spill behaviour allows for better arrangement and more efficient use of resources and the optimum development of antipollution action and tactics. The specific location of the Świnoujście harbour, its breakwaters shape, and that shipping traffic is allowed only on the approaching waterway, may lead one to the conclusion that the port of Świnoujście is completely safe from any possible petroleum pollution after a ships’ collision and the antipollution action should focus only on maximising the protection of the coast. To verify this assumption, simulations of an oil spill spreading after a vessels’ collision were carried out. The purpose of the simulations was to determine the most unfavourable weather conditions which would lead to the port of Świnoujście being polluted, and to define the best tactics for conducting oil spill combat actions under such conditions. The simulations clearly indicated that, with a particular combination of weather conditions, pollution could occur inside the port. It could result in vessel traffic suspension and huge financial losses. Simulations were conducted using the PISCES II oil spill simulator.

    At present, providing a clear presentation of the navigational situation around a navigator’s own ship (OS) is one of the most important issues facing device manufacturers. Integration of navigational devices on the bridge has made it possible to transfer information and present it in the form chosen by the navigator screen. However, this may cause a decrease in the clarity of information and hamper its interpretation. The ability to select the best information, and that which is most needed at a given moment, depends on navigator proficiency. Vectors are still the basic form of the graphic presentation of radar-tracked object data. However, the ability to track more objects at the same time in crowded areas results in a decrease in readability and can cause errors. This article introduces the possibility of presenting information about collision danger in the form of Dangerous Courses Sectors (DCS) together with an analysis of changes in these during typical ship encounter situations. DCS are calculated on the base of Dangerous Passing Areas (DPA) as bearings on the marginal points of these areas.
