The Scientific Journals (SJ) issued by the Maritime University of Szczecin (MUS) is a magazine which presents results of MUS research and educational activities. SJ has been published since 1973 but in 2004 it changed the ISSN from 0209-2069 to 1733-8670 as a result of MUS changing its name from Wyższa Szkoła Morska w Szczecinie to Akademia Morska w Szczecinie.

At the beginning there were several papers published in SJ and they were connected with maritime affairs. Doctoral and habilitation theses had also been published then. With time the SJ scope expanded to among others nautical issues, operation of the vessel, marine power plant operation. The magazine presented also symposium and conference proceedings.

Since 2008, the magazine has been published in A4 format with a new layout. Since 2010 the journal has been publishing the articles in English. By the end of 2014 a total of 112 Scientific Journals will have been published.

The SJ Scientific Board ensures high quality of published papers. All papers are reviewed confidentially and anonymously (double blind review) and are a subject of scientific edition.

The Scientific Journals printed version is primary.

    Dear Readers, With issue 57 (129), I have to say goodbye to you and my role as the Editor-In-Chief of the journal. On the 1st of February 2019, the Rector entrusted me with a new mission and asked me to oversee the entire publishing house of the University as its Head and Editor-In-Chief. I would like to express my gratitude for the trust placed in me by the University’s authorities. I would also like to thank the outgoing Editor-In-Chief of MUS Press, Prof. Bernard Wiśniewski, who has devoted several decades to MUS Press. During the last four years, I have managed to successfully complete many tasks, such as gaining sponsors and external funding from the Ministry of Science, establishing a recognised and international Scientific Board for the journal, designing and implementing detailed publication procedures in accordance with COPE regulations, designing and implementing an editorial system, designing and implementing an online journal repository with complete publications, modernising and uploading content to the journal’s website, gaining numerous renowned authors from around the world and introducing the quarterly to over a dozen indexes and bibliometric databases, such as Web of Science, DOAJ and InfoBase Index. All of those activities resulted in a continuous improvement in citability and other bibliometric indicators (Chybowski, 2018). I would like to use this opportunity to thank the members of the Scientific Board, the reviewers and the members of the editorial team for their cooperation and their efficient completion of the tasks related to the publication process. The time I spent as Editor-In-Chief taught me a lot about successful teamwork and shaping interpersonal relations. As of the 1st of February 2019, the role of Editor-In-Chief will be assumed by Dr Robert Jasionowski – Assistant Professor at the Institute of Basic Technical Sciences of the Maritime University of Szczecin. I am very happy that the mission relating to the further improvement of the journal’s ratings has been entrusted to this ambitious man. I sincerely hope that the new Editor-In-Chief will continue my quest of introducing the quarterly to the JCR database and gaining IF points. To achieve those goals, it is crucial to attract more international authors and continuously increase the citability of the published articles. I wish the new Editor-In-Chief all success in constantly improving the ranking of the Scientific Journals in peer-reviewed journal rankings and hope that the readers will continue to enjoy reading our quarterly publication.

    The purpose of this research was to investigate the power and thrust coefficients of a horizontal axis tidal stream turbine (HATST) with different blade geometries, including twist angles, blade numbers, and section profiles. The RANS equations and Star-CCM+ commercial software were used to numerically analyze these variables. Furthermore, the turbulence model used in this study is a Realisable k-ε turbulent model. Nine different models were defined by changing the twist angle, thickness, camber, and blade numbers. The results are presented, and the power and thrust coefficients are compared against TSR for each of the nine different models. The pressure distribution and flow velocity contour are also presented and discussed.

    Hot surfaces in ship engine rooms are the risk objects that most frequently contribute to fire ignition. Thermography, especially when using thermal cameras, offers many advantages over more common infrared thermometers, but dedicated systems are often prohibitively expensive. An affordable hybrid approach was thus tested in this study, where a low-cost thermal camera smartphone was paired with a common infrared thermometer. Measurements were taken in situ during a sea voyage in an engine room under normal operating conditions, and the surfaces of the main engine, the generating set auxiliary engine, and the exhaust gas boiler were tested. Several areas were discovered to be well above the generally-accepted temperature limit of 220°C, primarily due to absent or poor insulation. Clear recommendations for remediation are made, and the proposed testing method offers fast, easy, effective, and affordable inspection.

    Satellite navigation systems are commonly used to precisely determine the trajectory of transportation equipment. The widespread deployment of GNSS is pushing the current receiver technology to its limits due to the stringent demands for seamless, ubiquitous and secure/reliable positioning information. This fact is further aggravated by the advent of new applications where the miniaturized size, low power consumption and limited computational capabilities of user terminals pose serious risks to the implementation of even the most basic GNSS signal processing tasks. This paper has presented the advantage of Cloud-based GNSS Navigation, which facilitates the possibility of developing innovative applications where their particularities (e.g. massive processing of data, cooperation among users, security-related applications, etc.) make them suitable for implementation using Cloud-based infrastructure.

    The need for accuracy, precision, and data registration in underwater positioning and navigation should be viewed as no less stringent than that which exists on the sea surface. In the same way in which GNSS (Global Navigation Satellite System) receivers rely on the signals from multiple satellites to calculate a precise position, undersea vehicles discern their location by ranging to the acoustic signals originating from several fixed underwater acoustic sources using the Time-of-Arrival algorithm (ToA) through the Ordinary Least Squares method (OLS). In this article, the scope has been limited to only considering underwater positioning systems in which the navigation receiver is acoustically passive. The receiver “listens” to the buoys, receives their messages and solves the problem of finding its own position based on the geographical coordinates of the buoys. Often, such systems are called GNSS-like Underwater Positioning Systems (GNSS-like UPS). It is important to note the distinction between general purpose GNSS-like UPS (mainly civil systems) and special purpose GNSS-like UPS (mainly military systems). In this article, only general purpose GNSS-like UPS systems have been considered. Depending on the scale of system’s service areas, GNSS-like UPS are divided into global, regional, zonal and local systems. Only local GNSS-like UPS systems have been considered in this article. The spoofing of acoustic GNSS-like UPS works as follows: the acoustic GNSS signal generator transmits a simulated signal of several satellites. If the level of the simulated signal exceeds the signal strength of the real satellites, the acoustic receiver of an underwater object will “capture” the fake signal and calculate a false position based on it. All receivers that fall into the spoofing zone will calculate the same coordinates, while the receivers located in different places will have a mismatch in the XYZ coordinates.

    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

    This article describes the methodology to design a universal berth for LNG discharge from tankers with a wide cargo capacity range of 500 m3 to 220,000 m3. Based on a waterway optimization simulation, the methodology has been used to determine parameters of the designed universal cargo handling berth located in the port of Świnoujście.
