There are a number of empirical methods for determining the width of safe maneuvering areas for ships on waterways. These methods are relatively accurate for straight sections of waterways and less accurate for curves of the waterways. When designing waterways in detail or determining the conditions for their safe operation, more accurate methods (e.g., simulations) are used. However, such studies require relatively large expenditure involving the construction of simulation models of various vessels and water areas, and conducting a real-time simulation experiment with a sufficiently large number of maneuvers performed by highly qualified navigators (pilots, captains). This study deals with the problem of determining the width of safe maneuvering areas of ships on the bends of the waterway based on the results of simulation studies. A new empirical method was developed to determine the width of safe maneuvering areas of loaded bulk carriers passing through fairway bends under deteriorated hydro-meteorological conditions. The method was developed on the basis of a generalization of the results of many simulation experiments carried out at various stages of the Świnoujście–Szczecin fairway reconstruction and a determination of the safe operating conditions for ships passing through the fairway.

This paper presents the methodology, assumptions, and functionalities of an application developed during the realization of the project “South Baltic Oil Spill Response through Clean-up with Biogenic Oil Binders” (SBOIL). The SBOIL project is a continuation of the BioBind project, the primary goal of which was to develop and deploy an oil recovery system designed for use in coastal waters and adverse weather conditions. The goal of the SBOIL project was to use this new technology to improve the current response capabilities for cross-border oil spills. The developed application allows for the determination of the position of an aircraft at the time of dropping the oil binders, the determination of the oil binders’ position after falling in terms of a specific aircraft’s position, the determination of the position of oil binders after a certain time in order to plan the action of recovering it from the water surface, and the determination of the time when the binders will be in their assumed position.

The paper describes a universal simulation method used by the authors to determine the conditions of safe operation of sea ferries, in terms of marine traffic engineering. The assumptions, simulation experiment and results are described on the example of the m/f Mazovia manoeuvring in the Port of Ystad. Carried out and described in the article simulation study using the present method was aimed to determine the possibility of adapting the propulsion and steering systems of the ferry including:• determination of the wind limits in the Port of Ystad in terms of Mazovia ferry operation;• assessment of the maneuvering safety in a port area and determination of conditions of safe operation with present propulsion and steering systems;• determination of the possibility of adapting the propulsion and steering systems to meet the requirements of the shipowner for the economically efficient and safe operation of the ferry.

The article presents a simulation method for estimating the risk of grounding of a ship passing along the fairway in emergency situations This method consists in the determination of accident probability and utilizes a specially designed simulation experiment involving rudder jamming or engine blackout during ship passage along a dredged fairway. The method was used for risk assessment referring to grounding by an LNG tanker in the approach channel to the port of Świnoujście.

This paper presents assumptions and process of the forming of a risk assessment model for collision between a passenger ferry departing from or approaching port of Świnoujście and a chemical tanker carrying a dangerous cargo. In order to assess navigational safety on the basis of data obtained from AIS system, were prepared probabilistic domains of ships, which made it possible to estimate number of navigational incidents as well as their spatial distribution, that consequently allowed to determine potentially dangerous areas. The next phase was formulation of a simulative model intended for the calculating of probability of collision between the ferry and chemical tanker as well as the determining of characteristic scenarios for such collision. This paper presents also an analysis of consequences of the collision with taking into consideration a damage of cargo tanks.

The paper presents the assumptions of a simulation model for assessing the navigational safety of fishing vessels. The model consist of submodels of merchant and fishing vessels traffic, submodel of external condition and submodel of accident consequences. Paper present also a results of simulation experiment which was carried out for Polish EEZ. Model takes into account all Polish fishing vessels operating in the Polish EEZ with length more than 15 meters and the merchant vessels traffic in South Baltic Sea area. As a results positions of simulated collisions of fishing and merchant vessels, positions and sizes of simulated bunker spills and the positions of losses of fishing equipment were achieved.

Evaluation of Failure Probability of Ships on the Baltic Sea by Means of Simulation Model and Statistical DataThe ship technical failures contribution in overall number of navigational accidents are significantly smaller than those caused by human factor but in safety analysis they cannot be neglected. The paper presents stochastic modeling the technical failures of ships with respect of most important ship systems such as main engine, power generators and steering gear. The data for simulation was obtained from analysis of ships statistical data of polish owners. Obtained results could be useful for estimation of transport loses or potential environmental threats and planning the response action against them.

Models of Ships Groudings on Coastals Areas The paper presents description of models of ships groundings probability assessment on coastal areas. It also presents assumptions and preliminary results of new grounding model developed in Maritime University in Szczecin. This model was used in stochastic simulation model of comprehensive navigational safety assessment.

Construction of an LNG (Liquid Natural Gas) terminal by TGE (TGE Gas Engineering GmbH) is currently planned to be located along the Slovenian coast near the city of Koper. Two other LNG terminals are also plannedl: one in the Trieste port and the other off shore in Trieste Bay in Italy. Focusing on nautical operations, the purpose of this paper is to identify potential risks and to assess their levels as consequences of increased LNG activities. The ports in the area are host to a variety of vessels, including containers, tankers and chemical carriers, general cargo vessels, passenger ferries, bulk carriers, ro-ro carriers, etc.; and a large number of recreational and fishing vessels can be located on the navigational line towards ports located in Trieste bay. There are around 2500 vessels calling at the Port of Koper a year and approximately the same number at the Port of Trieste as well as a few hundred more nearby at the Port of Monfalcone. Using a quantitative approach, collision and grounding risk assessment will be analyzed for the shipping situation in the area, obtained through AIS (Automatic Identification System).
