Opis:
Reduction of ecological risks of shipping is a challenging task that requires methods of legislative and regulatory control, organizational measures, and technical and technological support. Furthermore, the matter concerns not only the reduction of possible risks but also the level of existing impact on the marine environment because of exhaust gas emissions by ships, discharge of waste and ballast water, as well as control of ecological consequences of accidents. The purpose of this study is to analyse possible sources of environmental impact during ship operation cycles, identify significant risks, review existing potentials to reduce the risk of ship accidents and their environmental consequences, and develop solutions to existing problems. This study offers results, which can serve as the initial basis for the formation of comprehensive measures on the reduction of environmental risks, and consequences of possible accidents for the environment caused by ships and international shipping.

This paper discusses the use of satellite tracking during an environmental disaster at sea, and it assesses the possibility of using remote sensing imagery captured by satellites using multispectral cameras and synthetic-aperture radar (SAR). This study is based on scientific literature and satellite tracking of the X-Press Pearl container ship disaster, which involved the EO-Browser platform. The purpose of this paper is to assess selected remote sensing methods for detecting and tracking marine pollution. The first part of the paper discusses satellite tracking of the X-Press Pearl disaster. The second part focuses on evaluation of the quality of remote sensing imagery from satellites and aircraft, when taking weather conditions into consideration. It should be noted that the research was conducted in real time when the incident occurred. News about the accident was also tracked in real time, allowing for a thorough analysis of the incident and, thus, an assessment of the different sensing systems. Although research on such disasters is crucial for the protection of the marine environment, scientific literature on this topic remains limited. This research area is very important for the protection of the marine environment, in the context of looking for solutions to these issues.

Opis:
Marine passenger ports and terminals are key transport facilities that influence the development and positioning of a region, city or country. The port infrastructure should provide the world requirements in service of cruise and ferry ships, and ensure the efficiency and convenience in service of passengers and associated cargo flow. This circumstance determines the necessity of infrastructure modernization, and hardware and software renewal. At the same time, the existing equipment in ports and terminals is gradually becoming outdated, hence the necessity of modernization on the basis of development of a decision-making system. This decision-making system should no longer be based on analytical models, but on new digital transport models of sea passenger ports and terminals. These digital models must take into account both passenger handling processes and external processes for handling cruise and ferry ships. The model should have high computational power and take into account the influence of the external environment. These models should answer development forecasting questions and provide an accurate decision-making system for the validity of infrastructure changes. The Passenger Port of Saint Petersburg "Marine Façade” (St. Petersburg) was chosen as the subject of research. To construct a numerical model, port operation intensity, passenger, cruise and ferry vessel handling processes were investigated; port and terminal development strategies and the mutual influence of the "city-port" systems on each other were studied. As a result of the analysis, a new digital transport model of the sea passenger port was built, which has a high level of detail and accuracy of process implementation, high productivity and efficiency of analysis of various infrastructure changes in the port, allowing the inclusion of dynamic changes from the external environment. The numerical model has been fully implemented for this port, and new conclusions have been derived from it. The use of these new models allows justification of infrastructure upgrades and to study the position of the port in the region in relation to competitors' ports. The developed tool allows solving the problem of research on port processes at any level of planning and enables integration into the information systems already existing in ports and terminals.

Opis:
World transport faces a serious challenge, which involves the detrimental impact of its activity on the environment. Marine transport is a significant link in the worldwide transport system, which provides the free flow of diversified cargoes and offers competitive prices compared to other modes of transport for the carriage of goods. Seaports enabling waterborne transport have a major impact on the economic, social and natural environment. Port managing authorities show growing awareness of the negative influence of port units on the surrounding environment. Concurrently, environmentally friendly measures are implemented in line with the principles of sustainable development. The article aim is to present the characteristics of the green ports concept in response to ports struggle with environmental problems. The article presents port development background and the evolving approach to environmental issues. The seaport in Gdynia is an example of pursuing a sustainable development policy, and informally is well embedded in the concept of green ports.

Opis:
The paper presents Energy Efficiency Operational Index (EEOI) introduced through International Maritime Organization (IMO) which defined the carbon dioxide emission as a result of transport specific cargo mass on specific distance. The total fuel consumption from all elements of vessel energetic system causes the carbon dioxide emission. Ship-owners should inform the marine administration about the fuel consumption from all vessels of 5000 tons of gross tonnage or more from 1st January 2018. In marine transport about 85% of carbon dioxide emission comes from such vessels. The calculating of EEOI is voluntary now but it is indicated to do it. It allows on an assessment the differences between the Energy Efficiency Design Index (EEDI) obligatory during design process of a vessel and its power plant and EEOI. Due to it may be estimated the correctness of vessel and power plant operation in exploitational conditions. The basic way of EEOI decreasing is slow steaming of a vessel. The power demand for propulsion (and fuel consumption) is proportional to the third power of vessel velocity (according to the propeller characteristics) on the other hand the hull resistance (the demand for thrust by propeller) is proportional to the second power of vessel velocity. As a result it causes the decreasing of total fuel consumption for covering the same distance but increasing the time of voyage. It is for acceptance during a bad economic situation. Although it will be no acceptable during a good economic situation when it will be required the increasing of vessel velocity (decreasing the time of voyage). The other effective methods are under research which allows to reach the same aim. It is known such methods of vessel operation which leading to the decreasing of that index. The paper shows these methods with their characteristics.
W artykule omówiono wprowadzony przez Międzynarodową Organizację Morską (IMO) wskaźnik zwany eksploatacyjnym indeksem efektywności energetycznej statku (EEOI), który określa emisję dwutlenku węgla w wyniku transportu jednostki masy ładunku na jednostkową odległość. Za emisję CO2 odpowiada zużycie paliwa przez wszystkie elementy okrętowego układu energetycznego. Od 1 stycznia 2018 r. armatorzy muszą zgłaszać do administracji morskiej ilość zużytego paliwa przez poszczególne statki o tonażu od 5000, które odpowiadają za 85% zużycia paliwa w transporcie morskim. Wyznaczanie wskaźnika EEOI jest obecnie dobrowolne, ale wskazane, aby go wyznaczać. Pozwala to na określenie różnic między projektowym indeksem efektywności energetycznej statku (EEDI), który jest obligatoryjny w procesie projektowania statku i elementów układu energetycznego, a eksploatacyjnym. Dzięki temu można oszacować poprawność eksploatacji siłowni i statku w warunkach rzeczywistych. Podstawowym sposobem zmniejszenia wskaźnika EEOI jest zmniejszenie prędkości eksploatacyjnej statku. Zapotrzebowanie na moc napędu (i zużycie paliwa) jest proporcjonalne do trzeciej potęgi prędkości statku (wg tzw. charakterystyki śrubowej), natomiast opór kadłuba (zapotrzebowanie na siłę naporu przez śrubę okrętową) jest proporcjonalny do potęgi drugiej prędkości statku. Skutkuje to zmniejszeniem zużycia paliwa na pokonanie tej samej drogi, ale wydłuża czas podróży. W okresie dekoniunktury na rynku żeglugowym jest to do przyjęcia. Jednak wraz z pojawieniem się oznak koniunktury, które będą wymagać wzrostu prędkości statku (skrócenia czasu podróży) będzie to niemożliwe. Poszukuje się więc innych skutecznych metod, które pozwolą osiągnąć ten sam cel. Znane są możliwości takich sposobów eksploatacji statku, które prowadzą do zmniejszenia tego wskaźnika. W artykule wskazano na te metody wraz z ich charakterystyką.

The paper presents the European Union’s approach to promote the advantages of short sea shipping as efficient and sustainable alternative solution to the global issues of road congestion. European Commission has made Short Sea Shipping one of the major priorities for European transport and maritime industries have made it one of their key areas for development. Short Sea Shipping plays an important role in reaching the objectives of the European Transport Policy, as it can help curb the forecasted substantial increase in heavy goods vehicle traffic, rebalance the modal shares and bypass land bottlenecks. In the paper are presented the advantages of Short Sea Shipping and the measures adopted by the European Union in order to better promote the use of this mode. Short Sea Shipping needs to be developed within an integrated and participatory approach, with the reliable involvement of stakeholders from the entire sector in order to fulfil its economic, commercial, social and environmental role.

Opis:
Marine passenger ports are integrated into the transport systems of cities and regions today. If there are sufficient developed mathematical forecasting models in the class of polynomial models, probability series, and a number of others, then the models describing the influence of the external environment on ferry market are not sufficient. The developed scheme of interaction between the participants of the cruise market and the mathematical model of the port as a technical system is presented in this research. The article substantiates new purposes to use the logistic function to assess the external environment. A mathematical model and the derivation of the new basic equation of the logistic function for ferry market are given. Analytical data were collected on the ports and terminals of the Adriatic Sea and the Baltic Sea, and data were selected of ship calls at the passenger port St. Petersburg “Marine Facade” (2019-2020). The article proposes the consideration of new various proportionality factors that will determine the demand for cruise transportation modeling in the short-term forecasting interval. A complete mathematical model is given taking into account the real schedule of the sea passenger port. The logistic function proposed in the article allows us to solve the forecasting problem in a new way in relation to the selection and evaluation of a cruise product. Moreover, it allows us to solve a group of economic problems related to promotion problem for particular cruise product on the market, allows us to evaluate the activity of passengers when they are choosing a cruise product, and allows us to make adjustments to the planned port working schedules and to make timely adjustments. The main advantage of the proposed model is an analytical assessment of the effect of the external environment, both on passenger ports and on ferry and cruise companies.

Opis:
Sea transport of liquid substances (petroleum and its derivatives) is done with the use of vessels called tankers. Their incorrect operation constitutes a great threat to the natural environment of maritime areas. Neglect of individual operations or failure to observe guidelines in many cases lead to oil spills the consequences of which are frequently irreversible and pose a threat to environmental safety. This article analyses the threats engendered by improper operation of oil tankers and describes how the operations necessary in transport of liquid substances with the use of tankers should be performed. It is an important issue since elimination of the abovementioned threats at the same time favours the efforts aimed at the highest possible degree of safety of marine natural environment (or more broadly ecological safety). The article also attempts to answer the following questions: Is the majority of disasters involving tankers caused by a human factor? Are the disasters rather caused by political factors and armed conflicts? The answer to those questions may form a basis for further research aimed at raising the level of marine safety.

Analysis of the possibilities of Poland’s participation in the utilization of hazardous chemicals based on the experience of the Danish RECLIB operation. The article reviews the implementation of the maritime policy by the Kingdom of Denmark as the examples of an operation, carried out in 2016, under the code name RECLIB, whose the main aim was to remove harmful chemical substances from Libya. The process of setting up maritime operation under the leadership of Denmark was described, while conducting an active international policy, including in the forum of the UN Security Council. The cooperation of Denmark with other countries was also presented, for which counteracting the weapon of mass destruction (WMD) proliferation, especially under the auspices of the United Nations, is a high priority in foreign policy. Finally, Polish extensive experience in the area of chemical weapon utilization was mentioned and an attempt was made to define the national ability to carry out a maritime operation of removing WMD from another country. For this purpose, the authors studied the CBRN capabilities and abilities of the Polish Navy to transport of dangerous substances as part of a potential naval operation.

Opis:
The great interest in the exploitation of sea deposits has in recent years resulted in the creation of many consortia conducting research on various methods of mining and transport to the surface. Exploitation of the shelf areas of crude oil and gas as well as solid minerals is successfully carried out in many places around the world using various methods. More and more often, however, we want to obtain natural resources found at great depths such as polymetallic nodules and massive polymetallic sulphides. This puts much greater demands on scientists and engineers. Unfortunately, solutions developed so far are characterized by high energy consumption. For several years, the authors have been researching new concepts of transport from the seabed. In previous years the authors presented theoretical research results of using a new method involving the use of pyrotechnic materials as a source of energy in transport from the seabed from large depths and experimental ones with the use of potassium nitrate and ammonium nitrate in a controlled pyrotechnic reaction and they compared three conceptions of transport of dredge spoil from the point of view of energy demand. This publication presents the results of the continuation of research, this time on the concept of building an autonomous transport module and its operating principles. The construction of the laboratory stand and the way of conducting experiments are discussed. The results of experimental research are presented, which confirm the possibility of using the discussed concept in transport from the seabed.

The growing interest in the exploitation of marine deposits has resulted in the development of research on deposits and technologies for their exploitation. For several years, the authors have been dealing with one of the most important problems in the deep sea mining of mineral deposits, namely transport from great depths. This publication presents theoretical considerations regarding the use of calcium carbide as a source of energy for transport from the seabed. The authors proposed three lines of the course of the decomposition reaction of calcium carbide and then analyzed the possibility of their use. From the obtained results it can be concluded that the maximum depth of use of a simple CaC2 distribution is about 1 km, while using the method proposed by the authors based on the "balance of forces" (using an additional medium) it is possible to apply this method to any depth occurring on Earth.

Opis:
The simulation as a tool for the design of port and terminals has emerged as an answer for the demand to enhance the quality and reliability of the project results. Very high costs of the project solution implementation and practically total lack of liquidity of transport infrastructure objects always induced the immense commercial risks in the terminal business. Lately these risks have multiplied significantly due to rapid changes on the global and regional markets of transport services. Today, many experts come to see this volatility as an indicator of the next phase in development of the global trade system and the derivative cargo transportation system, specifically the state of temporal saturation. The shift of the global goods volumes from quick and steady growth to relatively small fluctuations around constant values causes quick oscillations in re-distribution of demand over the oversized supply. This new business and economic environment seriously affected the paradigm of transport terminal design and development techniques. The new operational environment of terminals put a request for the designers to arrange the results not in terms of “point”, but in terms of “functions”. Eventually it resulted in development of the modern object-oriented model approach. The wide spread of this approach witnesses the objective demand for this discipline, while in many aspects it remains in the intuitive (pre-paradigmal) phase of its development. The main reason for it is in the problem definition itself, which usually is formulated as the simulation of a given terminal. At the same time, the task is to assess the operational characteristics of the terminal engaged in processing of a given combination of cargo flows. Consequently, it is not the terminal that should be simulated, but the processes of cargo flows handling performed by this terminal under investigation. Another problem that restricts the practical spread of simulation is in the model adequacy. A model which adequacy is not proved has no gnoseological value at all. The paper describes the approach aimed at development of the models with the features discussed above.

In recent years, we have observed a great interest in the exploitation of marine deposits by various methods of mining and transport to the surface. However, obtaining natural resources deposited at greater depths such as polymetallic nodules and seafloor massive sulphides - SMS creates a lot of challenges for both scientists and engineers. The solutions developed so far, unfortunately, have so far been characterized by high energy consumption. For several years the authors have been conducting theoretical and experimental research on new concepts of seabed to surface transport. The results of them have been presented in previous publications. This publication presents the results of the continuation of research on the concept of construction and operation of an autonomous transport module (submitted for printing). It focuses on a theoretical analysis of the change in gas phase density in the processes occurring during operation of the transport module intended for transport from the seabed. For this purpose, a reduced form of the van der Waals equation was used in the form of a third-degree equation for parameters interested from the point of view of the transport module.

Opis:
In recent years, oil spill accidents have become increasingly frequent due to the development of marine transportation and massive oil exploitation. At present, satellite remote sensing is the principal method used to monitor oil spills. Extracting the locations and extent of oil spill spots accurately in remote sensing images reaps significant benefits in terms of risk assessment and clean-up work. Nowadays the method of edge detection combined with threshold segmenta- tion (EDCTS) to extract oil information is becoming increasingly popular. However, the current method has some limitations in terms of accurately extracting oil spills in synthetic aperture radar (SAR) images, where heterogeneous background noise exists. In this study, we propose an adaptive mechanism based on Otsu method, which applies region growing combined with both edge detection and threshold segmentation (RGEDOM) to extract oil spills. Remote sensing images from the Bohai Sea on June 11, 2011 and the Gulf of Dalian on July 17, 2010 are utilized to validate the accuracy of our algorithm and the reliability of extraction results. In addition, results according to EDCTS are used as a comparator to further explore validity. The comparison with results according to EDCTS using the same dataset demonstrates that the proposed self-adapting algorithm is more robust and boasts high-accuracy. The accuracy computing by the adaptive algorithm is significantly improved compared with EDCTS and threshold method.
