    Opis:
    The probability of an accident in transportation systems can serve as a measure of these systems safety or risk, depending on the objective. Therefore numerous methods and models for risk evaluation, with respect to maritime, have been developed. However, these models are either too simplified, allowing relatively fast analysis but very often missing the substantial links among the model variables, or they are too slow for effective analysis, due to computational complexity, not necessarily being backed-up with the complexity of the model itself. Thereby, this paper introduces a novel method evaluating the probability of ship-ship collision in the maritime transportation system focusing on the open sea collisions, applying the queuing theory in the simulation model. The model allows relatively fast prediction as it focuses on the specific events (e.g. accidents), instead of simulating the whole traffic. To support this hypothesis a case study is presented focusing on a selected element of transportation system in operation.

    Opis:
    The maritime transportation system is increasingly a target of cyber attacks. This paper describes a taxonomy that supports the creation of adversarial cyber models, risk mitigation, and resiliency plans as applied to the maritime industry, using the Automatic Identification System as a specific illustration of the approach. This method has already been applied to the aviation sector; retooling it for a maritime example demonstrates its broad applicability to the transportation sector, in general.

    Opis:
    Zrównoważona żegluga (sustainable shipping) jest promowanym w ramach Międzynarodowej Organizacji Morskiej (IMO) kierunkiem rozwoju instrumentów prawnych międzynarodowego prawa morskiego, wynikającym z trzech praktycznych wymogów stawianych żegludze morskiej: „żadnych wypadków, żadnych zanieczyszczeń oraz obsługa na czas” (no casualties, no pollution and service on time). Na forum IMO uznano, że światowy przemysł żeglugowy funkcjonujący w międzynarodowych ramach regulacyjnych zmierza ku „zrównoważonej przyszłości”, co wymaga od IMO dalszego rozwoju instrumentów prawnych, w tym m.in. środków technicznych i operacyjnych, w celu zaradzania problemom globalnym. Główny nacisk kładzie się na: ograniczenie emisji gazów cieplarnianych (GHG) ze statków morskich; zmniejszenie zawartości siarki w paliwie żeglugowym; kontrolę i zarządzanie wodami balastowymi; zmniejszanie i kontrolę zanieczyszczeń morskich, w tym tworzyw sztucznych, oraz skuteczną ochronę szczególnie cennych ekosystemów morskich i przybrzeżnych; a także poprawę efektywności transportu drogą elektronicznej wymiany informacji, cyfryzację w żegludze morskiej i zwiększenie udziału kobiet w społeczności morskiej. Celem artykułu jest przedstawienie zrównoważonej żeglugi jako kierunku rozwoju instrumentów prawnych międzynarodowego prawa morskiego, opartego na ugruntowanej w prawie morza zasadzie prewencji oraz na obowiązku ochrony i zachowania środowiska morskiego.
    Sustainable shipping is a direction for the development of international maritime law legal instruments promoted within the International Maritime Organization (IMO), and resulting from three practical requirements for shipping: “no casualties, no pollution and service on time”. The IMO recognized that the global shipping industry operating within the international regulatory framework is heading towards a “sustainable future”, which requires IMO to further develop its legal instruments, including technical and operational measures to deal with global problems. The main focus is on: reducing greenhouse gas (GHG) emissions from ships; reducing the sulfur content of marine fuel; ballast water control and management; the prevention, reduction and control of marine pollution, including plastic pollution, and the effective protection of particularly sensitive marine and coastal ecosystems; as well as improving transport efficiency through electronic information exchange, digitization in shipping and increasing the participation of women in the maritime community. The aim of this paper is to present sustainable shipping as a direction for development of legal instruments of international maritime law, based on the principle of prevention and the obligation to protect and preserve the marine environment, well-established in the law of the sea.

    Opis:
    Efficient and effective transport system is the key element for the future development of European economy. Simultaneously, the process of transport development is connected also with the negative effects for environment and society. For that reason, the concept of internalization of all external costs of transport is developing in European Union. The concept characteristics and specificity in the maritime transport is the main issue of the following analysis. The special interest is focused on the maritime safety, one of the key external cost category.

    Opis:
    The implementation of the CSM regulation by the European Commission in 2009 which harmonizes the risk assessment process and introduces a rather new concept of judging changes within the European railway industry. This circumstance has risen the question how other technology sectors handle the aspect of modifications and alterations. The paper discusses the approaches for judging the significance of modifications within the three transport sectors of European railways, aviation and maritime transportation and the procedure which is used in the area of nuclear safety. We will outline the similarities and differences between these four methods and discuss the underlying reasons. Finally, we will take into account the role of the European legislator and the fundamental idea of a harmonization of the different approaches.

    Opis:
    This article tries to show the relationship between one important set of deficiencies included in the Paris Memorandum of Understanding on Port State Control procedures, propulsion and auxiliary machinery, the importance of this set of deficiencies for the PSC inspection and also its importance for the Maritime Safety. The maintenance of the propulsion and auxiliary machinery systems has become less important that it deserves, that means while the ship sails everything is supposed to be properly maintained, this is the most extended policy in the Companies and accepted and supported by the Owners. This article studies the deficiencies included in the category propulsion and auxiliary machinery detected by the Port State Control Officers (PSCO) of the Paris MOU area, and tries to demonstrate how important they are in these inspections. At the same time can be seen the professional profile of the PSCO’s as well as the assessment made by them of those areas included in this set of deficiencies.

    Opis:
    The aim of this article is to dispel any nomenclatural confusion related to the notion of FSRU. Sometimes FSRUs are classified as ships or vessels; sometimes as stationary units. The article will attempt to explain in which case FSRUs may be classified as ships. This article describes one of the most persistent legal problems in Polish maritime law, which is the FSRU implementation in the Baltic Sea. The application of FSRU solutions was analysed in relation to LNG maritime transport. This analysis is concerned only with a fragment of wider theoretical considerations about the placement of the definition of the ship in different national legal systems as well as the importance of translation and correct understanding of the words denoting the ship or the vessel.

    Opis:
    This study aimed to determine the concepts learned in Navigation and Seamanship as well as the level of satisfaction of students’ in using the training ship in terms of food, accommodation, readiness of venue, quantity of equipment, activities, speakers, and ships’ crew. The respondents of this study were the 129 students of JBLFMU-Arevalo. They were selected through stratified and cluster sampling. A questionnaire was sent to the respondents through e-mail and Facebook messenger to gather the data. The comments of the students were classified according to themes. For BSMT 1 – Familiarization and Ship Tour, in Navigation, the themes are learning the ship nomenclature and manipulating the different navigational equipment onboard, inculcating skills to plan and manage a ship for safety voyage, employing the concepts learned about the various ship positioning to arrive at the port or point of destination, and refining the importance of learning the qualities of a competent navigator. In Seamanship, the themes are enhancing concepts learned about the importance of prioritizing safety on board and learning the International Maritime Law, learning the important purposes and uses of the different navigational equipment on board, improving skills on proper operation of the ship, and uplifting the duties and responsibilities of officers and crew members on board. For BSMT 2, Port and Anchor Watch, in Navigation, the themes are, learning the uses and importance of the different navigational equipment on board, different types of navigation use to navigate accurately, employing the concepts learned about the various ship positioning to arrive at the port or point of destination, uplifting the duties and responsibilities of officers and crew members on board, and defining navigation for watercraft. In Seamanship, the themes are learning about anchor operations, familiarizing different parts of the ship, integrating seamanship skills in navigation, enhancing concepts learned about the importance of prioritizing safety on board, learning mooring operation, and definition of seamanship. For BSMT 3, Navigational Trip, in Navigation, the theme is learning the different navigational equipment on board and for Seamanship, improving seamanship skills. Having different themes for every year level indicates that the students have actually learned various knowledge about Navigation and Seamanship during their stay onboard the training ship. For the students’ level of satisfaction, the grand mean is described as “High”. This means that some aspects are good in terms of food, accommodation, venue, quantity of equipment, activities, speakers, and ships’ crew. This study concludes that the concepts learned by students’ in Navigation and Seamanship varies in each activity. Furthermore, the students were highly satisfied in using the training ship’s amenities in terms of food, accommodation, readiness of venue, quantity of equipment, activities, speakers, and ships’ crew. The researchers recommend another follow-up study to include respondents from other units as well and some other non - JBLFMU/JBLCF students utilizing the training ship to further validate the results, reduce the number of students participating in every activity to optimum to maximize the outcome intended for each activity, and finally, create a multiple choice questionnaire to assess better the concepts learned and to be given personally to the respondents.

    Opis:
    This quasi-experimental study aimed at looking into the effectiveness of blended learning approach in improving the performance in Information, Communication, and Technology (ICT) Course of Bachelor of Science in Marine Transportation (BSMT) first year students at JBLFMU-Arevalo during the second semester of school year 2018-2019. The respondents of this research were the two sections comparable with each other who were enrolled in the subject ICT. There were 40 student respondents composed of 20 in the experimental group and 20 in the control group. A validated and reliability-tested 45 item researcher-made multiple choice test was used as an instrument with a Cronbach index of 0.88. The statistical tools used were mean, standard deviation, Mann-Whitney test, and Wilcoxon-Signed ranks test set at .05 level of significance. The effect size was computed to determine the effectiveness of the blended learning approach in terms of students’ performance in ICT. Results showed that in the pretest, though the experimental group had a higher mean score than the control group, the Mann-Whitney test showed that the mean scores of the two groups were comparable because the significant value was greater than .05. When the treatment was introduced, findings showed that there were significant differences in the ICT performance in the pretest and posttest of experimental and control groups as well as in the posttests of both groups. Results inferred that blended learning approach was more than a hundred percent effective showing significant results on the experimental group. It could also be inferred that the better performance of the control group could be attributed to the traditional method of teaching, the lecture method.
