Opis:
In recent years, various types of commerce including transport have suffered significant damage and costs due to cyber-attacks. The geographic scope of freight transportation has no boundaries, attacks can be launched almost anywhere there is an Internet connection. Therefore, there is no immunity from the failure of computer systems and information of delivery processes in the networks of organizations and companies engaged in maritime transportation. In addition, while the consequences of cyber-attacks on major shipping lines and ports, as well as the digital systems of logistics companies, can be comprehensively analyzed, the vulnerability of ships remains insufficiently studied. This paper offers an analysis of the risks in the field of maritime freight transport and the main factors of influence such as digitization on the safety of the transport process. The basic threats to the information system of the ship are defined and the techniques of risk analysis for the ship information security is proposed.

Opis:
The Turkish Merchant Shipping Industry has recently witnessed an increasing awareness of the importance to minimize environmental pollution and fuel oil consumption. Together with certain non-governmental organizations and media concerns about environmental protection, the International Maritime Organization (IMO) has been strict on controlling undesirable effects on the environment and, consequently, forcing shipping companies to minimize their emissions. Besides, today’s highly advanced technology companies over the world have developed various innovative systems that can be utilized to minimize carbon emission, thus giving assurance to relevant investors that their investments are most likely to turn out well with a considerable financial gain in the short or long term. Despite all such favorable developments, in a general look, shipping companies seem reluctant in making use of technologies providing efficiency in energy consumption. This reluctance has eventually brought about the term “Energy Efficiency Gap”. This research conducts a questionnaire, created by Acciaro et al. [1], among the shipping companies in Turkey. 20 respondent companies, who represent 26 percent of the Turkish owned merchant marine fleet of over 1000 gross tonnage in terms of deadweight cargo capacity, participated in the research. The Pearson correlation analysis was used, and interpretations were made according to the obtained statistical values. The aim of the research was to identify reasons and points restraining the use of new technologies regarding energy efficiency, as well as to develop proposals for the innovators in this field about how to overcome this handicap concerning technical and managerial aspects of gaining energy efficiency.

The paper has been written within the European EUREKA Project E!2772, initiated and completed at the Faculty of Ocean Engineering & Ship Technology, Gdansk University of Technology in the years 2001-2003. A problem has been solved concerning mathematical optimisation of a fleet of multipurpose sea-river vessels for European short-shipping reguIlar lines, in the area of The North and Baltic Seas, on the level of marine transportation , task, by the non-linear programming methods with constraints. A method is proposed which enables existing criteria of stability to be included as constraints in the optimisation model of a jleet. In the numerical examples, three typical criteria of intact stabiliry: by IMO, PRS, and HSMB have been selected to demonstrate a post-optimisation feasibility analysis of principal parameters of ships.

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:
Development and implementation of various projects focused on improving standards of energy efficiency and rational use of energy carriers is a priority for numerous enterprises and companies. Modern shipping devotes sufficient attention to improving the environmental performance of the fleet. As part of the strategy to improve environmental safety and energy efficiency, as well as to reduce air and marine pollution in industries, including maritime transport and shipping, a set of steps to improve the ship's energy efficiency is being implemented. This process is carried out in various ways, however, at the same time maintaining the economic indicators of fleet operation. Relevant is the research aimed at analyzing the introduction of energy management systems in the maritime transport and summarizing the experience of operating the ships, which allows to identify a number of proposals, the implementation of which allows to maintain the economic efficiency of transportation. The article offers a review of the main energy efficiency tools and ways to ensure the transport efficiency of existing ships without modernization by operating them at reduced speeds and fuel consumption and thereby minimizing carbon emissions, as well as developing a set of measures to improve the environmental efficiency of cargo transportation.

Opis:
As in every industry at risk, the human and organizational factors constitute the main stakes for maritime safety. Furthermore, several events at sea have been used to develop appropriate risk models. The investigation on maritime accidents is, nowadays, a very important tool to identify the problems related to human factor and can support accident prevention and the improvement of maritime safety. Part of this investigation should in future also be near misses. Operation of ships is full of regulations, instructions and guidelines also addressing human factors and safety culture to enhance safety. However, even though the roots of a safety culture have been established, there are still serious barriers to the breakthrough of the safety management. One of the most common deficiencies in the case of maritime transport is the respective monitoring and documentation usually lacking of adequacy and excellence. Nonetheless, the maritime area can be exemplified from other industries where activities are ongoing to foster and enhance safety culture.

Opis:
A paradigm shift is presently underway in the shipping industry promising safer, greener and more efficient ship traffic. In this article, we will look at some of the accidents from conventional shipping and see if they could have been avoided with autonomous ship technology. A hypothesis of increased safety is often brought forward, and we know from various studies that the number of maritime accidents that involves what is called “human error” ranges from some 60‐90 percent. If we replace the human with automation, can we then reduce the number of accidents? On the other hand, is there a possibility for new types of accidents to appear? What about the accidents that are today averted by the crew? This paper will present a method to assess these different aspects of the risk scenarios in light of the specific capabilities and constraints of autonomous ships.

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.

According to Eurostat, in 2015 freight maritime transportation was responsible for 51% of share in transportation of overall EU international trade, what places it as a first transportation mode in Europe. [1] This is an important trigger for engineers to develop new solutions in ships’ construction, which could enhance the optimization of costs and increase efficiency of maritime transportation. The publication presents two big on-going research projects, which will define the future in ships’ technologies. First one, Maritime Unmanned Navigation through Intelligence in Network (MUNIN) and second, Ship Intelligence belonging to Rolls-Royce. In the first chapters, the article says about the latest trends according to European Union strategy in terms of maritime transportation. The third and the fourth chapter present both of the research projects in their current state. At the end, the author analyzes and compares both projects providing an overview how it meets the strategy for the future of cargo transportation in Europe, indicating the most important features.
Obecnie obserwuje się wzrost znaczenia transportu morskiego. Według badań przeprowadzonych przez Eurostat, w 2015 transport ładunków drogą morską posiadał 51% z ogólnego podziału na środki transportowe dla ładunków, co oznacza, iż transport morski cargo jest drugim środkiem transportu w Europie. Fakt ten jest istotny dla inżynierów, aby wprowadzać nowe rozwiązania w konstrukcji statków morskich, które mogłyby zoptymalizować koszty oraz zwiększyć efektywność transportu morskiego. Publikacja prezentuje dwa duże projekty, które mogą zadecydować o przyszłości konstrukcji i technologii statków morskich: europejski projekt Morska Bezzałogowa Nawigacja poprzez Inteligencję w Sieci (MUNIN) oraz Inteligentne Statki wdrażane przez brytyjską firmę Rolls-Royce.

Opis:
Looking at the high flow of the shipping industry and many things related to the ship operations that have to be done every day, several ship owners have collaborated with Ship Management Company (SMC) to assist them in managing their ships' operations. SMC is required to be responsible for the daily operational management of the ship on behalf of the ship owner such as crewing, technical management, administration, and chartering. Seeing the importance of collaboration and the diversity of services provided by the SMC, it is necessary to evaluate each determinant factor by the ship owner for the selection of an SMC to assist the ship owner in choosing an SMC that suits their needs. It is also to improve the service prioritized by the owner to SMC. The purpose of this research is to identify the determinant factors of SMC selection from the owner’s perspective, evaluate the importance of each of these factors, and obtain different views between the owner and SMC in the selection of ship management. The Fuzzy Analytical Hierarchy Process (Fuzzy AHP) method is used for evaluating weight based on the opinions of the owners and SMC who are experts in their fields. Then, the different perspectives between the owner dan SMC were obtained from the processing result. The results show that owners placed their top priority on factors that they can get the most from SMC, such as human resource factors and services. Meanwhile, SMC placed its priority on cost and its services factors that described the things they must manage well and optimization provided to owners.

Opis:
The paper presents a model for risk analysis regarding marine traffic, with the emphasis on two types of the most common marine accidents which are: collision and grounding. The focus is on oil tankers as these pose the highest environmental risk. A case study in selected areas of Gulf of Finland in ice free conditions is presented. The model utilizes a well-founded formula for risk calculation, which combines the probability of an unwanted event with its consequences. Thus the model is regarded a block type model, consisting of blocks for the probability of collision and grounding estimation respectively as well as blocks for consequences of an accident modelling. Probability of vessbl colliding is assessed by means of a Minimum Distance To Collision (MDTC) based model. The model defines in anovel way the collision zone, using mathematical ship motion model and recognizes traffic flow as a non homogeneous process. The presented calculations address waterways crossing between Helsinki and Tallinn, where dense cross traffic during certain hours is observed. For assessment of, a grounding probability, a new approach is proposed, which utilizes a newly developed model, where spatial interactions between objects in different locations are recognized. A, ship at a seaway and navigational obstructions may be perceived as interacting objects and their repulsion may be modelled by a sort of deterministic formulation. Risk due to tankers running aground addresses an approach fairway to an oil terminal in Skoldvik, near Helsinki. [...]
W artykule przedstawiono model oceny ryzyka w transporcie morskim, w aspekcie kolizji statków oraz wejść na mieliznę. W modelu przyjęto jeden typ statków, tankowce do przewozu ropy naftowej, z uwagi na fakt, iż w przypadku wystąpienia kolizji lub kontaktu z dnem statek ten może stanowić bardzo poważne zagrożenie dla środowiska. W pracy przedstawiono dwa nowatorskie podejścia do modelowania prawdopodobieństwa wystąpienia powyższych wypadków. Model do oceny prawdopodobieństwa kolizji statków definiuje w nowy sposób strefę kolizji, w oparciu o właściwości manewrowe statku oraz jego hydrodynamikę. Intensywność ruchu morskiego na analizowanym akwenie modelowana jest w oparciu o proces niestacjonarny, w przeciwieństwie do istniejących modeli. Model oceny prawdopodobieństwa wejścia na mieliznę wykorzystuje model grawitacyjny, który wyznacza bezpieczny obszar manewrowy dla danego statku i danego akwenu. W modelu tym statek i otaczające go płycizny traktowane są jako masy, wzajemnie na siebie oddziaływujące. Obydwa modele wykorzystują dane o ruchu statków zarejestrowane w systemie automatycznej identyfikacji statków (AIS). Analiza ryzyka przeprowadzona została dla dwóch wybranych akwenów w Zatoce Fińskiej. Jako konsekwencje wypadku przyjęto model kosztów, skonstruowany w oparciu o dane statystyczne z międzynarodowego funduszu IOPCF, który pokrywa koszty w związku z rozlewem olejowym na morzu.

Changes in Oil Transportation
Opis:
This paper covers the current state of maritime oil transportation in the Baltic Sea and the development of oil transportation in the 2000s, as well as estimations of transported oil volumes in 2020 and 2030 in the Gulf of Finland. The scenarios were formulated on the basis of a current state analysis, energy and transportation strategies and scenarios and expert assessments. The study showed that the volumes of oil transportation in the Gulf of Finland will increase only moderately compared to the current status: 9.5-33.8 %, depending on the scenario. Green energy policy favours renewable energy sources, which can be seen in the smaller volumes of transported oil in the 2030 scenarios compared to the 2020 scenarios. In the Slow development 2020 scenario, oil transport volumes for 2020 are expected to be 170.6 Mt (million tonnes), in the Average development 2020 187.1 Mt and in the Strong development 2020 201.5 Mt. The corresponding oil volumes for the 2030 scenarios were 165 Mt for the Stagnating development 2030 scenario, 177.5 Mt for the Towards a greener society 2030 scenario and 169.5 Mt in the Decarbonising society 2030 scenario.

Opis:
In this paper we analyse several ways to compute the weights from the Regularized Han (RH) algorithm, the regularized version of Han’s algorithm for approximating the least squares solutions of inconsistent (incompatible) systems of linear inequalities. We tested our approaches on a classical transportation problem, aiming to provide a cost optimized solution to real world transportation problems, which often are unbalanced and inconsistent.

Opis:
Nowadays managers and decision-makers around the world seek every opportunity to lower costs of the ship’s mooring time at seaports. In this article, main operations taking place at maritime container terminals are first disaggregated in several elementary activities. Then the vessel cycle time is analysed while separately investigating the STS (Ship to Shore) crane cycle time, the RTG (Rubber-Tyred Gantry) crane work cycle time and the IMV (Internal Movement Vehicle) transfer time. A triangular distribution describes times of each of the container handling stages while the PERT (Program Evaluation and Review Technique) method is used to estimate the total time for all reloading activities. The paper demonstrates the proposed method effectiveness with data of Baltic Container Terminal (BCT) Gdynia. The use of formulas developed for the calculation of times of individual operations that affect the reloading of a container at maritime container terminals enables an in-depth assessment of the effectiveness of the reloading processes. Thus, the proposed tool gives terminal managers opportunity to track which stage of the container reloading consumes most time and generates biggest costs.

Opis:
Large-scale distributed transportation systems can pose various risks in terms of fatalities, environmental pollution, or loss of property. In particular, accident where a vehicle carrying large number of passengers is involved may pose a high risk with respect to human casualties, moreover it will immediately raise a public and political concern. This is an issue in case of maritime transportation systems (MTS), as the biggest ships nowadays can carry up to 8500 people at once (m/s Oasis of the Seas). Thereby lot of effort has been put to increase safety of ships carrying passengers; however the holistic approach to model and manage the risk existing in the MTS is still missing. This paper makes an attempt to fill this gap, by presenting a data-driven model evaluating risk level in the existing MTS and by introducing a systematic methodology for mitigating the risk. Moreover the MTS operating in the Gulf of Finland under non-ice conditions is addressed, where heavy passenger traffic is observed.

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:
Providing safety and maintaining high quality of dry cargo, transported by sea, is associated with the necessity of taking into consideration their specific property, which is hygroscopicity. Susceptibility to the impact of water, which also occurs in vapour state, concerns mainly dry cargo, which are organic matter, containing carbohydrates and protein in their composition. This is because these substances have strong connection with water. The example of a bulk cargo often transported by sea is soybean meal, which is mainly produced in the USA, Brazil and Argentina. Due to its economic importance, the quality of soybean meal, which is globally used in the animal nutrition (poultry and swine), remains an important research issue. This product is obtained by subjecting the soybeans to cracking and dehulling processes, in order to facilitate the extraction of the oil. Water absorption of soybean meal causes reactions taking place in it, which leads to the changes in its chemical composition and, consequently, also in its nutritional values. Moreover, increasing the water content, leading to the increase of water activity, may significantly deteriorate the microbiological safety of the meal. Therefore, the research was undertaken to determine whether the sorption properties of soybean meal will change due to the influence of a static, homogeneous magnetic field. This aim has been achieved by determining and comparing the water vapour adsorption isotherms. The comparison of the isotherms determined under normal conditions and under the influence of a static, homogeneous magnetic field with an induction of 10 mT has been made on the basis of empirical data. Furthermore, using the Brunauer, Emett and Teller equation (BET), the monolayer and the energy constant of the sorption process have been estimated. The isotherms were determined at 20°C. The study lasted 9 days. Desiccators with aqueous supersaturated solutions of substances and a generator of a static magnetic field were used in the research. The obtained results have indicated that the influence of the magnetic field is a factor that causes the differentiation between the sorption properties of soybean meal expressed in the volume of the monolayer and the energy associated with the sorption phenomenon. The inferred findings show, that the magnetic field has an impact on the course of the sorption phenomenon in organic samples, and may determine the stability of the cargo during long-term maritime transport.

Opis:
Kompleksowe zagospodarowanie dolnej Wisły ma na celu zaspokojenie potrzeb różnych dziedzin gospodarki, transportu, turystyki, energetyki, ochrony przeciwpowodziowej, rolnictwa i leśnictwa. Celem artykułu jest wykazanie, że kompleksowy rozwój śródlądowych dróg wodnych jest wyzwaniem aktualnym i ważnym dla gospodarki, w tym zwłaszcza dla pozycji konkurencyjnej portów morskich. Problem ten zostanie przedstawiony na przykładzie dolnej Wisły. Do badań zastosowano metodę analizy koszty/korzyści. W świetle problemów, związanych z nadmiernym obciążeniem infrastruktury transportu samochodowego i kolejowego, wykorzystanie transportu wodnego śródlądowego na zapleczu portów morskich Gdańska i Gdyni pozwoliłoby na uzyskanie dodatkowych korzyści związanych ze zmniejszeniem kosztów transportu i degradacji środowiska. Najważniejszym efektem będzie jednak umocnienie pozycji konkurencyjnej portów trójmiejskich oraz zwiększenie dochodów państwa. Badania wykazały, że ekonomiczny wskaźnik koszty/korzyści (Benefit Cost Ratio) kompleksowego zagospodarowania dolnej Wisły kształtuje się na poziomie 6,11, co świadczy o wysokiej opłacalności tego przedsięwzięcia.
Multipurpose development of the lower Vistula will benefit in various areas of the economy in: transport, tourism, energy, flood protection, agriculture and forestry (reduction of losses associated with drought). The aim of the work is to demonstrate that the multipurpose development of inland waterways is a current and important challenge for the economy, especially for the competitive position of seaports. This problem will be presented on the example of the lower Vistula. In the research was used the method of cost / benefit analysis. In light of the problems associated with excessive overload of road and rail transport infrastructure, the use of inland waterway transport in the hinterland of seaports Gdańsk and Gdynia would provide the additional benefit of reducing costs of transport and, external costs, however the most important result, will to strengthen the competitive position of the port of Tri-City and to increase state revenues. Research has shown that the economic cost / benefit ratio of multipurpose development of the Lower Vistula River stands at 6.11, which testifies to the high profitability of the project.

Opis:
The economic and social impact of the waterborne sectors in Europe cannot be overstated, employing directly more than 3 million people and generating a turnover of about €250 billion representing more than 1% of the EU’s GDP. In order to maintain its leadership and competitiveness, Europe must take advantage of new market opportunities and address these challenges by means of focused research, development and innovation. In recent years the impact of digital technology and relevance of geospatial information has been increasingly felt across the whole maritime community bridging waterborne and coastal activities. The challenge for the maritime and marine science communities is to accelerate the transformation of the maritime sector into one that is able to exploit market-led opportunities and create high value added outputs that fully embraces technological and scientific advances. e-Maritime offers itself as the enabling framework.
