    The vessel traffic system (VTS) operator is an important role in the monitoring and supervision of maritime traffic. The main objectives of the VTS is to improve security in the coastal areas. VTS efficiency depends on the quality of the operators. Certain conditions of work should be provided if the system service is to be reliable as this facilitates proper and effective task performance. This article analyzes the factors affecting the performance quality of VTS operator’s. The aim of this study is to examine the methods that indicate negative factors affecting the efficiency of the VTS operator. The result of the study is primarily a reliability analysis of VTS, which underlines the importance of a thorough understanding of the factors associated with human reliability. These methods are crucial to determining VTS operator errors, and gaining an understanding of the consciousness of the operator’s actions in the workplace. Future negative factors can potentially be eliminated by answering questions about the guiding forces, actions and reactions of the operator to external stimuli in a specified scenario.

    This article presents the underlying concepts of a mathematical model optimizing the routes of vessels carrying dangerous goods proceeding in the vicinity of passenger ferries. The method is based on the estimated risk of collision between a chemical tanker and a passenger vessel. Risk assessment was performed using three models. The first model determines the distance of the passing ships on the selected area on the basis of the AIS data. The second one is a stochastic model of navigational safety assessment, which provides statistical data on the probability of collision between the two chosen types of vessels. The third model determines the consequences of collisions between passenger ships and chemical tankers. The study defines the scope of the parameters affecting the objective function of vessel route optimization and their importance in the optimization problem

    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.

    This paper presents the method used for the creation of ship traffic models in Southern Baltic Traffic Separation Schemes (TSS). The analysis of ship traffic was performed by means of statistical methods with the use of historical AIS data. The paper presents probabilistic models of ship traffic’s spatial distribution and its parameters. The results showed that there is a correlation between the standard deviation of traffic flow and TSS lane width that can be used in practical applications to ensure the safety of navigation; improve navigation efficiency, safety and risk analysis in given area, and for the creation of a general model of ship traffic flow.
