Maritime surveillance from space is useful for many applications, such as fisheries control, maritime border control and maritime security. A new generation of satellite-borne Synthetic Aperture Radars is able to provide resolutions of down to 1 meter. In the case of maritime targets, however, their motions lead to blurring in the SAR images, so these high resolutions cannot be attained. Scientific research into how to surmount the existing limits on the use of high-resolution images for maritime surveillance would be of great utility. In this context, high resolution SAR data were collected from ships that have been fitted with motion sensors in order to understand vessel motion impact on detection and recognition capability

First LNG import terminal on the Baltic Sea will be located in Poland at the outer port of Świnoujście. Safe entrance to the port of LNG carrier (vessel of length abt. 300 m) to the terminal requires considering of technical and navigational aspects, as well as fulfilment of series of safety criteria related to manoeuvring, mooring and unloading of LNG C carrier (LNGC). Complex manoeuvring, mooring and unloading safety assessment of LNG in port, might be done as an assessment of particular types of manoeuvres and exploitation operations.

Navigational systems employed at LNG terminals assist the navigation of gas carriers along approach chan-nels and in port waters leading to LNG terminals. i.e. in restricted waters. The navigation in restricted waters is often referred to as pilot navigation. The term is derived from the fact, that a pilot assists in navigating through restricted areas, and the process of marine navigation the pilot participates is called pilotage

The paper presents basics of the eye tracking methodology and results of preliminary test on multi-purpose marine ship’s navigation bridge simulator. The use of the eye-tracker on the navigation bridge makes it possible to objectively measure the ergonomics of the individual interfaces, as well as to evaluate the decision-making process itself, including the mental workload and stress. In the experiment, officers were faced with an unexpected and sudden situation leading to a collision. The simulated situation required the officer to act immediately and resolutely, taking into account all his/her knowledge about the ship, and interpreting the available data correctly. Outcome of this test was compared with gaze data and it was proved that experienced group with best results suffered lowest level of mental workload and was most efficient in decision making process. Based on those results a possibility of improving simulator training with the use of eye tracking data is discusse

The paper presents stages of stochastic ship traffic stream model creation which was applied for the optimization of different solutions for the Świnoujście–Szczecin waterway design. The model is based on Monte Carlo methodology and is microscopic, which means that each ship’s model is treated as a separate object possessing given attributes. The main output from the model is the sum of the delay time of waiting ships and the distribution of ships’ queue. Two alternative waterway traffic solutions with different passing places for ships were analyzed in this study and compared with each other. The model was used for the first time for the optimization of the modernized Szczecin–Świnoujście waterway in respect of two different solutions of passing places for ships.

Vessel maneuvering in restricted areas requires expert knowledge (usually that of a pilot who is a specialist in a given area). To minimize the influence of shipboard equipment on pilot decisions, it is proposed to create a pilot navigational system (PNS). One of the PNS components is an electronic compass. The article looks into se-lected compass technologies. The accuracy of AMR (anisotropy magnetoresistive tech-nology) electronic compass has been assessed.

A single polymer composite comprises a composite built out of fibres and a matrix, both made of the same or a very similar polymer material, where the components may differ with: molecular mass, density or branching degree. Such thermoplastic composites provide the beneficial mechanical characteristics required for reinforced materials, and their great advantage is the ease of full material recycling after the end of use. The aim of the presented work is to provide a description of the manufacturing technology, with a definition of the possibility for the waste of single polymer polyester composites to undergo a full material recycling process, oriented towards use in shipbuilding. A proposed idea for recycling is in the preparatory stage and its assumptions and the process followed will be the subject of a patent application. This work forms part of the studies realized in the scope of the REP-SAIL Project under the ERA-NET Transport III Initiative Future Travelling, carried out at the Maritime University of Szczecin, and the prepared doctoral thesis entitled “Manufacturing, shaping of operational properties and recycling of single polymer composite materials”.

This method, using results of empirical research and simulation methods, would allow accurate determination of safe manoeuvring areas. The method was used at the stage of detailed design of parameters of the, which is undergoing modernization, to determine the optimum parameters of horizontal curves of the fairway.

The aim of this research was to develop a stochastic model of a navigator’s attention distribution during their navigational watch. Such model could be used as a tool for workload and usability studies for navigators and navigational equipment interfaces. A structure of the model is discussed together with the evaluation of Markov chains as a main modelling tool. Initial results are presented and discussed. It is suggested that 1st order Markov chains are not fully applicable for this problem. A combination of the 1st and higher-order Markov chains will be applied in the next stage of research.

This article presents a method of obtaining relative and global coordinates using the Global Navigation Satellite System (GNSS). Four GNSS antennas have been compared in this research. The GNSS antennas have been utilized by the Veripos and Septentrio Systems. Global Positioning System (GPS) pseudorange observations are used to obtain relative position of the GPS antennas. Relative positions are based on calculations made by the RTKLIB software. Lever arm range and bearing are used to assess accuracy of the true antenna location relative to the vessel Navigation Reference Point (NRP). The article deals with the problem of assessing the quality of real-time positioning equipment. Comparing results of the raw position calculation with the physical measurements shows the usefulness of the real – time position monitoring.

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.

The article presents a simulation method for determining the minimum safe pull of tugs assisting in port manoeuvres. The method can be used to determine the relationship between the minimum safe pull, understood as the tension on the line, of the assisting tugs and the overall length, cargo capacity or net capacity of ships manoeuvring in a given port under allowable hydrometeorological conditions. The method was verified through simulated tests of gas tankers’ entry, turning and berthing at the LNG terminal of Świnoujście
