Opis:
The paper deals with the most essential trends and types of changes in the last three editions (2001–2005–2009) of BC/IMSBC Code concerning the shipment of specific group of loads such as solid bulk cargoes. Since the general trend of changes in the content layout has been proved advantageous due to its standardized information in relation to all types of hazardous cargoes (A, B, C groups), its continuation aimed at facilitating the use of the Code in shipping operation is justified. Examples of detailed as well as extended information concerning technological shipping quality determinants of solid bulk cargoes enabling a better choice of appropriate technology of marine transport have been presented. The essence of information relationships resulting from the knowledge of particular quality determinants with the possibility of their practical technological application has been pointed out.
W artykule przedstawiono najważniejsze kierunki i rodzaje zmian w trzech ostatnich wydaniach Kodeksu BC/IMSBC (2001–2005–2009), dotyczącego przewozu morskiego bardzo specyficznej grupy ładunków, mianowicie stałych ładunków masowych. Stwierdzono, że przy generalnie korzystnym kierunku zmian co do układu treści, ujednolicającym formę przekazu informacyjnego w odniesieniu do wszystkich ładunków, tj. stwarzających różnorodne zagrożenia (grupy A, B i C), uzasadnione jest ich kontynuowanie, celem ułatwienia wykorzystania Kodeksu w praktyce transportowej. Podano przykłady uszczegółowień i rozbudowy informacji w zakresie determinantów jakości technologiczno-transportowej ładunków sypkich przewożonych luzem, pozwalających na zwiększenie stopnia zapewnienia wyboru i zastosowania prawidłowych technologii przewozu morskiego. Wykazano istotę powiązań informacyjnych, wynikających ze znajomości określonych determinantów jakości z możliwością ich praktycznego, technologicznego wykorzystania.

Opis:
The paper addresses the sensitivity of a novel method for quantifying the environmental risks associated with the current-driven transport of adverse impacts released from offshore sources (e.g. ship traffic) with respect to the spatial resolution of the underlying hydrodynamic model. The risk is evaluated as the probability of particles released in different sea areas hitting the coast and in terms of the time after which the hit occurs (particle age) on the basis of a statistical analysis of large sets of 10-day long Lagrangian trajectories calculated for 1987–1991 for the Gulf of Finland, the Baltic Sea. The relevant 2D maps are calculated using the OAAS model with spatial resolutions of 2, 1 and 0.5 nautical miles (nm) and with identical initial, boundary and forcing conditions from the Rossby Centre 3D hydrodynamic model (RCO, Swedish Meteorological and Hydrological Institute). The spatially averaged values of the probability and particle age display hardly any dependence on the resolution. They both reach almost identical stationary levels (0.67–0.69 and ca 5.3 days respectively) after a few years of simulations. Also, the spatial distributions of the relevant fields are qualitatively similar for all resolutions. In contrast, the optimum locations for fairways depend substantially on the resolution, whereas the results for the 2 nm model differ considerably from those obtained using finer-resolutionmodels. It is concluded that eddy-permitting models with a grid step exceeding half the local baroclinic Rossby radius are suitable for a quick check of whether or not any potential gain from this method is feasible, whereas higher-resolution simulations with eddy-resolving models are necessary for detailed planning. The asymptotic values of the average probability and particle age are suggested as an indicator of the potential gain from the method in question and also as a new measure of the vulnerability of the nearshore of water bodies to offshore traffic accidents.

Opis:
The fast development of marine transport causes a lot of environmental concerns connected with possible accidents of ships transporting hazardous cargoes as well as oil pollution coming from an exploitation of engine rooms. Moreover, a significant problem is connected with a ballast water handling. The use of ballast water is necessary for the safe movement of large ships. Namely, in maritime transport a ship unloading causes a reduction in its draft - it is a cause of lower steering or even completely prevents the safe movement of the ship. Therefore, in place of the discharged freight the ballast water is collected (often just during the unloading). This water is pumped out from a ship at the site of re-loading. However, this implies the risk of transportation of living organisms over large distances, which (if at the point of discharge of ballast water will find suitable conditions) can become invasive species. Because of the risks involved in carriage of these organisms, the International Maritime Organization (IMO) has developed rigorous standards for permissible amounts of organisms in the discharged ballast water. A number of methods of biological neutralization of ballast water, that meet the requirements of the IMO, have been developed. The topic of this paper is to review currently used methods of neutralization of ballast water. We consider clearing of ballast water from point of view of physics, especially by using electromagnetic radiation and ultrasonic waves.

Opis:
Shiporigin operational discharges of oil mainly include the discharge of bilge water from motor rooms, fuel oil sludge and oily ballast water from fuel tanks. Also, various tankers can illegally discharge of tank-washing residues. Accidental discharges can appear when ship collide or come in distress at sea (e.g. engine breakdown, fire, explosion, pipeline breaks). There is necessity of continuous inspection of marine shipping routes, especially in environmentally sensitive areas (e.g. whole Baltic Sea). If protection against oil pollution is considered - the coastal nations of the North Sea are formed in the Bonn Agreement, whereas coastal nations of the Baltic Sea are formed in the HELCOM convention. Both organizations carrying out the international aerial surveillances and manage international oil-combat systems. Unfortunately, air surveillance can operate mainly in good weather, good visibility and in daylight. The surface of the whole world is observed independently on the time of day and weather by antennas of Synthetic Aperture Radars (SAR) of dozen military satellites with resolution of several meters. Some civil satellites equipped with SAR, supply every few days a set of signals which in ground-based centres are transformed to image of a define area of the sea surface. In these images, the shapes of places, which can be interpreted as polluted by an oil film, are shown. The system is introduced after EU directive and managed by European Maritime Safety Agency (EMSA). EMSA has developed the CleanSeaNet service - a satellite based monitoring system for marine oil spill detection. Advantages and limitations of the SAR-methods are discussed in this study. Physical, meteorological and hydrological as well as organizational conditions for effective use of this system are considered.

Opis:
The Baltic Sea area has already been intensively used by variety of maritime economic sectors such as marine transport, fishing, tourism, extraction of sand and gravel and oil and gas exploitation. This is also an area of relatively intense military penetration. In addition, this is a place of various other investments, e.g. coastal technical infrastructure (port and transhipment terminals constructions, as well as technical measures of the shoreline defence against transgression of the sea), electrical energy transmission systems (high voltage cables plus large scale electrodes) and natural gas transmission huge pipelines. Over the next decades, the use of the Baltic Sea will expand rapidly, particularly due to constructions of new coastal and offshore wind farms, electrical energy transfer network, further intensification of various forms of shipping, development and construction of new ports and terminals and installing new oil extraction platforms. Some of these activities influences natural spatial distribution of physical properties of the sea space (such as acoustic field, magnetic field, salinity distribution etc.) as well as disturb different natural processes (such as natural coastal dynamics, sedimentation, migration patterns of mobile species etc). In order to present this problem, most important existing activities as well as the most recent large-scale constructions in the Baltic Sea are selected and presented in this study (with emphasis on the Polish Exclusive Economic Zone). Moreover most likely disturbances of natural distributions of physical properties of marine space are analyzed in light of the impact on the environment

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.

Opis:
The Baltic Sea belongs to a global system of protected area and has a status of Particularly Sensitive Sea Area (PSSA) which results in a mechanism for strict control on International shipping activities within designated areas through the UN International Maritime Organization (IMO). Countries can declare such areas, and then establish rules for their protection. Additionaly almost the entire Polish coastline has been notified to the European Natura 2000 sites. Inside coastal NATURA 2000 areas some places are covered by increased protection because of belonging to a system of coastal and marine Baltic Sea Protected Areas (HELCOM BSPA). On the other hand intensive shiping in the vicinity of the Polish coast, high population density in the coast, tourism as well as coastal and marine industry necessitate special attention in relation to environment protection. Therefore, inter alia, novel techniques for the surveillance of purity of coast and coastal water are desirable. In the case of large spill - existing combating system provides only partly reducing ofamount of oil entering the sea environment. Elimination ofa greatest number of small oil spillages or discharges is possible, if well developed techniques and organization systems is used. The paper presents pre-project assumptions for small multifunctional ship designed for inshore activity — especially for port inspections and service, as well as for removal of floating and submerged rubbish and combating small oil spillages. We have analyzed possibility to achieve expected exploitive features of the ship using present knowledge for construction of small ship hulls applying principles of engine and navigational equipment steeringfor choosing the best route and for optimization the water surface cleaning-works as well as to minimize the energy consumption. We expect, that this ship - owing to main designations thanks to modern technical equipment and sophisticated software -will also fulfill conditions as an educational or as a training vessel.

Opis:
The escalating maritime transport as well as offshore crude oil exploitation and pipeline transportation leads to the increase of feasibility of the discharge of petroleum substances to the sea environment events. Therefore, it is necessary to rapidly detect of oil pollution to minimize the extent of contamination in the seawater. The aim of this study is to discuss the assumptions of the optical methods using for detection of oil pollution in the seawater. We consider the different approaches of oil-in-water detection using spectral active and passive techniques with emphasis on fluorescence techniques. The intensive development of scientific apparatus and methods in light spectroscopy leads to build various airborne or underwater specialized devices (UV-, IR-scanners, fluorosensors), which allows to detect oil pollution in relatively large areas of the sea. The possibility of measurements of oil pollution in the seawater is particularly important for monitoring, especially in very difficult weather conditions and highly waved sea surface. Such possibilities should be given by devices for in-situ measurements based on time-resolved fluorescence. Such measurements allow obtaining the significant information about presence of oil in really short time. As we show in this study, the wide-range development of fluorescence techniques opens the diagnostic opportunity not only for detection of the oil-in-water content but also for identification the type of oil directly in seawater or even determination of the source of oil pollution.

A sea voyage can be divided into three parts with varying degrees of risk: • from the berth at the port of departure to the pilot disembarkation point • from the pilot disembarkation to another pilot embarkation point near the port of call/destination • from the pilot embarkation point to the berth Results of statistical research into ship accidents at sea point to an increased number of incidents and accidents, including groundings, especially in restricted areas. Such areas are often narrow and have limited depths, while their short straight sections require frequent course alterations, often in varying hydrometeorological conditions. Due to all these factors, the voyage has to be carefully planned and all watchkeeping officers have to be well prepared to conduct the ship safely. The article presents the objectives, scope, legal basis and stages in the process of voyage planning. The compliance with the outlined principles will reduce the level of risk in maritime transport.

Growing intensity of marine transport results in the increase of the amount of oil pollution released into the sea water. The presence of oil in the sea, which is thought to have come from accidental spills or tanker disaster, is connected mainly with the daily operation of marine engines. Pollution from ships engines, can reach the sea water masses together with ballast or bilge water as the result of human error or a failure of marine equipment. This paper is focused on a comparison of the optical properties of marine waters and oil substances. These include the spectra of absorption coefficient, spectra of scattering coefficient and scattering phase-function (for different wavelength) which describes an angular distribution of scattered light intensity in the sea water. The light scattering phase function depends on the water constituents like mineral suspensions, zooplankton and phytoplankton cells, gas bubbles or so-called yellow substances as well as oil droplets of water pollution. Detection of oil substances in the sea can be effective when it is done remotely, from ships, buoys, inshore or offshore towers, the decks of aircraft or satellites. The knowledge of the listed above properties of natural (clean) seawater is necessary, because they determine the field of light coming out from the sea and allow interpret images of sea surface from point of view of crude oil and the petroleum products detection. In this study we also discuss optical contrast of oil residuals in the sea in various sea regions.

Opis:
Ship engines emit noxious gases (SO2, NOx, and VOC) and particulate matter (PM), mostly black carbon. Since 1990, the International Maritime Organization (IMO) regulations gradually restricted the level of emission of NOx, which since 2016 have to be lower than 2-3.4 g/kWh, depending on engine power. SO2 emission reduction has begun since 2010 and now the content of sulphur in marine fuels is limited to 3.5%. At the same time, the Sulphur Emission Control Areas (SECA) has been established, at which the sulphur content in fuel cannot be higher than 0.1%. Since 2020, only a fuel of 0.5% sulphur can be used at all cruising areas outside SECA. It should be noted that due to lack of efficient technology, IMO still has not issued regulations regarding the PM emission by ships. The paper discusses various electrostatic techniques used for the reduction of PM emission in Diesel engine exhausts. Electrostatic scrubber systems, using seawater, allow removal of PM from exhausts with high efficiency and simultaneously SO2 gas. Electrostatic agglomerators allow increasing submicron and nanoparticles by coagulation of those particles to the larger ones, which could be removed by conventional techniques.

Opis:
This paper describes an application of the dynamic programming method to determine the safety of one’s own ship trajectory during encounter of other ships. A dynamic model of the process, with kinematic constraints of state and determined by a three-layer artificial neural network has been used for the development of control procedures. Non-linear activation functions in the first and second layers may be characterised by a tangent curve while the output layer is of a sigmoidal nature. The Neural Network Toolbox of the Matlab software has been used to model the network. The learning process used an algorithm of backward propagation of the error with an adaptively selected learning step. The considerations have been illustrated through an example implemented in a computer simulation using the algorithm for the determination of the safe ship trajectory in situations of encounter of multiple ships, recorded on the ship’s radar screen in real navigational situation in the Kattegat Strait.

Opis:
The paper introduces the process of safe ship control in collision situations using a differential game model with m participants. The basic model of process includes non-linear state equations and non-linear, time-varying constraints of the state variables as well as the quality game control index in the forms of game integral payment and final payment. As an approximated model of the manoeuvring process, a model of a multi-step matrix game in the form of a dual linear programming problem has been adopted here. The Game Control (gc) computer program has been designed in Matlab/Simulink software in order to determine the own ship safe trajectory. The considerations have been illustrated with computer simulation examples using the gc program for determining safe own ship trajectory in real navigation situations when passing commonly-encountered ships.

The presented paper concerns the disturbed traffic of vessels, the passage through the waterway intersection. To determine a time between subordinated vessels leaving the intersection a convolution operation has been used. The main factor disturbing the traffic stream of subordinated units is speed reduction on the intersection area. To model times needed to speed changes a normal distribution has been used.
Niniejszy artykuł dotyczy zaburzonego ruchu statków, przechodzących przez skrzyżowanie dróg wodnych. Do wyznaczenia czasu pomiędzy jednostkami podporządkowanymi, opuszczającymi skrzyżowanie wykorzystano operację splotu. Głównym czynnikiem zaburzającym strumień ruchu jednostek podporządkowanych jest ograniczenie prędkości na obszarze skrzyżowania. Do modelowania niezbędnych czasów, w których następują zmiany prędkości, wykorzystano rozkład normalny.

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.

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.

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 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.

The shortest circular path around these ports is found and discussed. Formulation of the problem accounts for the fact that distances between the individual cities are not the same in both directions. The consequences that arise from this situation are studied. The used algorithms are based on graph theory and standard logistic methods. In addition, the results are compared with the results obtained by using a minimum spanning tree algorithm.

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:
The article is a review of the transport problems that appear in a marine intermodal terminal. The importance of intermodal terminals has been increasing since the 1980s as a result of the development of containerized international trade. This increase in the handling of containers cause problems connected with securing adequate space for container storage or efficient usage of available terminal loading equipment such as cranes, AGVs, straddle carriers or terminal tractors with trailers. The equipment of a terminal depends mainly on the size of containers flow. The use of this equipment determine the terminal technology and work organization. That is why the classification of intermodal container terminals is presented in chapter 2. This classification was made according to different criteria. To understand transport problems, the identification of processes performed in the marine intermodal terminal is presented in chapter 3. For the purpose of research an example of an intermodal marine terminal with its individual functional areas is presented. Finally, the literature review on research conducted on the transport processes performed in the terminal are presented in chapter 4. These processes refer to quay side and land side horizontal transport operations. Additionally, the arrangement of containers at the storage yard was investigated.

Opis:
The configuration of a marine propulsion system is selected with regard to the maximum power resulting from its maximum design speed and displacement. The propulsion systems of high speed vessels use three or even four propellers, and each propulsion unit may be multi-engine. High speed vessels are designedfor maximum speeds, but their factual exploitation speed parameters are usually considerably lower - partial speed. In such cases particular propulsion propellers and engines need to be shut down. The idle propellers are dragged by the hull and they work in the so-called turbine work mode; they transfer torque to the shaft and generale negative thrust, i.e. additional resistance. Additional resistance contributes to reducing estimated speed of a vessel and increasing fuel consumption. What is more, torque generated on a propeller is transferred to the shaft and when friction resistance torque in shaft stuffing-boxes and bearings, transmission and, possibly, the propulsion engine is exceeded, mobile components rotate as a result, reaching considerable rotational speed values. torque and thrust on a propeller in this work mode may be estimated on the grounds of universal hydrodynamic characteristics of propellers. Universal hydrodynamic characteristics of propellers are used as reversion characteristics in evaluating the steering properties ofa vessel, and may be useful in evaluating resistance of free wheeling and locked propellers in marine multi-shaft propulsion systems. This paper presents charts of universal hydrodynamic characteristics of propellers for the full range of their rotational speed, the methodology and an example of calculating resistance of free wheeling and locked propellers for the given marine propulsion system.

Opis:
In the operating marine diesel engines the indication diagnostics tests are usually performed through a 0.5-1.0 me ter long indication channel which delays and disfigures the pressure signal being measured. the delay depends on the engine 's speed and load. the pressure sensor itself together with an amplifler is an additional source of delay and disfigurements, so the registered pressure curve is displaced even if theTDC piston's position hadbeen estimated with the highest accuracy. when the over exploited engine is being tested the angle of delay can achieve several degrees and differ for each cylinder. in that case cylinders' load is unequal and torsional vibrations occur in the engine operation. in case when some simplifying assumptions have been adopted the part of diagnostic information is lost what could lead to a false diagnosis. in the paper the attention is focused on the mistakes which could be made in the marine diesel engine diagnostics when different TDC assessment methods are used. TDC corrections with compression pressure analysis are possible only in case when crankshaft angle position is precise. in case of measurement with constant frequency such corrections are possible only when the engine is good balanced.

Opis:
As the time is passing, lubricating oil in marine engine lubricating oil system loses its quality because of oil deterioration process. Lubricating oil quality influences the wear of tribological system elements. The total base number (TBN) is one of the most important oil quality properties. During operation of diesel engines the TBN decreases as alkaline additives are exhausted mainly through neutralization offuel burning acid products. So as to improve lubricating oil properties an engineer uses some maintenance methods. One of these methods is refilling process. The paper presents theoretical researches of total base number changes modelling at various lubricating oil refilling methods. Theoretical model of oil-deterioration process was worked out on the basis ofmass balance equation of total base number. The method of sofaing the problem, structural model of experimental unit, total base number change in case of constant refilling process, calculating example, total base number changes in PIELSTICK12PC2-5V engine oil versus parameter d, percentage changes of total base number in PIELSTICK 12PC2-5V engine oil versus parameter d are presented in the paper.

Results of studies that aim was to develop a diagnostic method for WOLA marine diesel engines type H are presented in this paper. These engines are high-speed type units used to drive small vessels or more often to drive ship generators. Polish Navy is operating significant number engines of this type. Motors of this type do not have indicator valves, which complicates the assessment of their technical condition in exploitation. These engines also, because of their age, are relatively poorly equipped in control and measurement devices. In the era of cost reduction in operation of marine equipment there is also tendency to reduce the cost of maintenance and repair of diesel engines. One way to avoid malfunction of the motor can be systematic monitoring of the technical condition of selected critical systems using reliable diagnostic methods. Polish Naval Academy (PNA) in Gdynia for years has been doing research on methods of diagnosing marine internal combustion engines. In recent years, a diagnostic method for high-speed diesel engines based on the analysis of envelope of vibration accelerations generated by the valve gear mechanism and fuel system of WOLA type H engines has been developed. Preliminary tests were carried out on a six-cylinder WOLA engine type 57H6Aa in the Marine Power Plant Operation Laboratory in PNA. Verification tests were conducted on twelve-cylinders WOLA engines of the same type on navy vessels. The developed method allows determine the angles of opening and closing the fuel injection valves and angles of closing intake and exhaust valves during engine operation. Using this method it could not be clearly determined opening angles of intake and exhaust valves.

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.

Determination of the internal combustion piston engine 's indicated power is a complex task. A number of difficulties lead to lots of solutions utilized to increase the accuracy of the result. This paper reports on the experiments concerned with a four stroke engine's piston dynamic position determination. Although the paper is mostly concerned with the piston's TDC definition, the experimental methodology can be utilized in the entire piston movement determination. A specially developed measuring assembly and its working principle utilized in the experiment have been presented too. It allows the acquiring of a set of time-position coordinates. Based on the coordinates, the mathematical algorithm for dynamic piston positioning can be developed. As the piston movement was being observed from the crankcase side, the methodology proved to be relatively cheap and easier for installation, compared to proximity sensors installed in the cylinder head. The advantage of optical sensors and light pipes being used was reduction of the explosion risk in oil mist environment inside the crank case.

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.

In the paper, some results achieved during the tests of high-speed marine diesel engine WOLA 57H6Aa type are presented. This type of engine is still broadly use on Polish Navy vessels and on some civilian ships built in Polish shipyards, mostly as auxiliary or emergency generator. Several types of engine malfunction had been simulated especially in fuel injection system and in valve gear mechanism. The malfunctions were connected with fuel valve opening pressure, intake and exhaust valves clearances. During the tests engine speed and load had been changed in tolerant operation range. The tests were devoted to prepare some new diagnostic methods, which could be used on these types of marine diesel engines. Diagnostic methods, which based on vibration and acoustic signals analysis are usually sensitive on engine load and speed changes. During the tests, different methods based on vibration and acoustic signals processing in frequency domain were used. Set of applications possible to use by B&K PULSE system together with acoustic and vibration sensors were applied to analyse of signals changing by different types of simulated malfunctions. Aim of the research was to check if the acoustic and vibration signals generated by the engine systems and components analysed by B&K PULSE system with CPB measurement give possibility to find such parameters, which are unequivocal, strongly connected with different object structure parameters, easy to asses and measure.

Opis:
The piston engine irregularity is a consequence of the uneven power supply from the engine units. As such, it contains valuable information about engines units working process. Unfortunately, it is strongly influenced by torsional vibration, resonance, and propeller behaviour. In order to better understand the speed irregularity phenomena the instantaneous speed was recorded and its characteristic against engine mean speed was developed. Some statistical parameters: standard error and deviation as well as variance were determined. The results were compared with propulsion plant torsional vibration. The presented results show that the irregularity of the long stroke engine's speed is strongly influenced by torsional vibration phenomena. The analyzed engine has a bared speed range 37-43 rpm. Exactly around that range, the speed irregularity reaches its maximum values of 18% of mean speed. The analysis can be considered as qualitative look into the phenomena. However even based on the presented analysis one can observe some practical inferences. The common type of electronic indicators is used to simplify the measurement by assuming that the shaft speed is equal in between the pickup pulses. In order to increase the accuracy of the indicated power determination the use of such instrument should be avoided in the speed range, which is a multiple number of the barred speed. Due to the fact that the shaft speed is irregular especially in the ranges where torsional resonance may occur the piston positioning (for example for TDC determination) purpose procedure should take it into account.

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.

Natural gas, being the cleanest burning fossil fuel, will play a key role in the future. Liquefying natural gas lets moving it to regions where pipeline transport is not possible, allowing end-use markets access to natural gas. LNG is more energy dense than gaseous natural gas, so there using fields are still increasing in end-use applications, e.g. different types of transportation (heavy duty vehicles, marine or rail applications). Global LNG demand is expected to grow, mostly because of new economic markets from Asia and Middle East.

The current status of EGNOS (December 2006) is described as Initial Operations Phase and the EGNOS Open Service is just about to be formally declared as available for non-safety of life service. In meanwhile the EGNOS Signal in Space is provided almost in its nominal level and delivering, when available, the nominal system performance. New positioning technologies, such as EGNOS in Europe, create a new quality in marine navigation and bring further improvement of the maritime transport safety. It may be expected that very soon EGNOS will find significant interest among the maritime community serving as the augmentation system in the maritime transport applications of GNSS. The paper discusses the EGNOS status and the expected EGNOS performance in the context of marine navigation requirements. The system performance analysis is backed with the study of the various field tests results where the EGNOS positioning performance was verified by author in the experimental way.

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.

High speed vessels are designed for maximum speeds, but their factual operation speed parameters are usually considerably lower — partial speed. In such cases particular propulsion propellers and engines need to be shut down. The idle propellers are dragged by the hull and they work in the so-called turbine work mode; they transfer torque to the shaft and generate negative thrust, i.e. additional resistance. To estimate torque and thrust on a propeller in this work mode universal hydrodynamic characteristics of propellers may be used. This paper presents the methodology and an example of calculating resistance of freewheeling and locked propellers for a given marine propulsion system.

Opis:
Although perceived as the most environmentally friendly means of transport, ships are a significant source of pollution to the environment. The vast majority of emissions in EU sea areas are emitted from cargo ships over 500 GT. About 45% of all emissions come from EU flagged ships and approximately 20% of emissions are emitted within the 12-mile limit of territorial seas. In port cities, ship emissions are in many cases a dominant source of pollution and need to be addressed when considering compliance with legally binding air quality objectives. Moreover, emissions from ships travel over hundreds of kilometres and can thus contribute to air quality problems on land even if they are emitted at sea. This is particularly relevant for the deposition of sulphur and nitrogen compounds, which cause acidification of natural ecosystems and threaten biodiversity through excessive nitrogen inputs. Emission of toxic compounds in marine engines exhausts is limited by international legal provisions, namely MARPOL convention, which in Annex VI sets limits to SOx and NOx emissions and designates special areas where the limits are stringent. To comply with the provisions, marine vessels need to be equipped with installations reducing emissions to permissible levels or turn to alternative fuels. The paper presents evaluation of impact of those having been in force for the last decade limitations as well as of applied new technological solutions on improvement of air quality. The analysis was conducted for the Baltic Sea, based on available data on ship traffic in the area and emission factors.

Opis:
The European transport policy undertakes to enhance sustainability in transport in order to boost economic activities in the whole EU. The reduction of pollutant emissions and a better balance among modes of transportation to cut road congestion are the pillars of the above policy. These factors are encouraging public and private stakeholders to use the freight maritime alternative more extensively. Short sea shipping is considered the quickest way to reach sustainability. Another advantage of ships over trucks and trains is that vessels consume less fuel as a result of the relatively low speeds at which they travel. However, increasingly faster ships are in a position to compete with trucks, but the former’s greater power demand and consumption rate result in higher pollutant emission levels which, in turn, lead to the loss of their environmental advantage over road transport. This problem is analyzed below.

Opis:
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:
Large demand for energy results in necessity for its transportation in various ways. On land areas, energy media transfer consists mainly of transport in tanks by rail, road or river routs as well as pipeline systems for liquid or gasified hydrocarbons. A part of energy media in the world is electric energy flowing though metallic conductors of overhead and cable networks. If sea areas are considered, ship navigation routs crosses with pipelines and electrical energy transfer systems. Furthermore, every transport system can interfere with other. Marine areas occupied by pipelines and submarine cables must be excluded from use of anchors and bottom fishing gear. On the other hand, pipeline systems interfere with the free development of navigation, particularly in areas near ports. Power transfer systems modify the natural force fields in the water column, surface water and even in near-water layer of atmosphere. In this article, we show the main ways of transferring electricity in the sea and the resulting modifications of physical fields: electrical, magnetic and electromagnetic ones. We also discuss the probable impact of modifications of natural fields on ship traffic as well as corrosion of hulls of ships and marine structures. The considerations presented in the article are related primarily to the Polish Exclusive Economic Zone of the Baltic Sea.

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.

Opis:
This work indicates that new and innovative materials used in the construction of floating and stationary marine structures can contribute to increased operational safety in addition to reduced service costs and frequency and other reduced operating costs, including the costs of staff and running maintenance. Such materials include metal-ceramic composites whose properties, such as high resistance to abrasive wear, favourable coefficient of friction, good thermal conductivity and low thermal expansion, allow them to be used in tribological pairs in mechanisms, control elements and actuators of various devices operating in marine power plants, thereby increasing their operational reliability. Properties of metal-ceramic composite foams, i.e. vibration and noise damping, good thermal insulation performance, dissipation of electromagnetic waves and absorption of explosive energy, make them ideal for use in shipbuilding and construction of drilling towers, at the same time increasing the levels of comfort during operation. Composite metal-ceramic foams can significantly reduce the effects of fires as they are durable, water-resistant and creep resistant thermal insulators which can limit the destruction (deformation) of steel structures. This paper presents proposals for the application of these materials to selected technical solutions in offshore structures.

Opis:
The paper presents key legal instruments governing the issues of the protection of the marine environment with respect to the management of ship-generated waste and cargo residues in European Union seaports. In view of the observed development of maritime transport, it is particularly important to organise the reception of wastes and cargo residues in seaports, in line with the principle of sustainable development. As a result of the harmonisation of the relevant legal regulations, Member States of the European Union and port and harbour authorities have taken a number of measures over the last few years to arrive at optimum solutions in this respect. The main objective of the paper is to analyse the existing system of environment al fees, the calculation criteria for such fees, and the techniques used in selected European Union seaports to submit ships’ waste notifications. The research is aimed, inter alia, at determining which of the solutions that are now used in Rotterdam, Antwerp and Klaipeda could possibly be optimal for the ports in Szczecin and Świnoujście.

Opis:
Celem artykułu jest identyfikacja najważniejszych czynników kształtujących działalność przeładunkową w małych portach morskich, na przykładzie portu w Darłowie w latach 2008–2015. Na podstawie dostępnych źródeł stwierdzono, że potencjał przeładunkowy portu darłowskiego nie był w pełni wykorzystany, chociaż w okresie 2008–2015 przeładunki istotnie wzrosły. Głównymi czynnikami wzrostu działalności przeładunkowej były: inwestycje portowe, rozpoczęcie działalności przez operatorów portowych, lokalna aktywność gospodarcza oraz poprawa infrastruktury drogowej umożliwiającej dostęp do portu od strony lądu. Dalsze zwiększenie przeładunków wymaga poprawy infrastruktury portowej, hydrotechnicznej oraz wykorzystania do przewozu towarów transportu kolejowego. Szansą na zwiększenie przeładunków może być utworzenie darłowskiej podstrefy ekonomicznej. Perspektywy rozwoju działalności przeładunkowej portu darłowskiego są obiecujące. Port w Darłowie może stać się znaczącym ośrodkiem przeładunkowym wśród małych portów morskich w Polsce.
The paper aimed at identification of main factors shaping reloading turnover in small marine ports between years 2008 and 2015, exemplified by the port of Darłowo. Basing on available sources, authors stated that reloading potential of the port was underutilized. However, in the period 2008-2015 reloading activity substantially increased. Main reasons were: port investments, starting activities by port operators, local economic activities as well as improving road infrastructure connected with the port. There are chances for further increase reloading activities by improving port infrastructure and hydrotechnical facilities as well as using railway for transporting commodities to and from the port. Another chance of increasing port activities may be creating Darłowo economic sub-zone. There are good perspectives for reloading turnover growth in the future. The port of Darłowo may become an important centre of reloading turnover among small sea ports in Poland.

The maritime industry plays a crucial role in the global economy, with roughly 90% of world trade being conducted through the use of merchant ships and more than a million seafarers. Despite recent efforts to improve reliability and ship structure, the heavy dependence on human performance has led to a high number of casualties in the industry. Decision errors are the primary cause of maritime accidents, with factors such as lack of situational awareness and attention deficit contributing to these errors. To address this issue, the study proposes an Ant Colony Optimization (ACO) based algorithm to design and validate a verified set of instructions for performing each daily operational task in a standardised manner. This AI-based approach can optimise the path for complex tasks, provide clear and sequential instructions, improve efficiency, and reduce the likelihood of human error by minimising personal preference and false assumptions. The proposed solution can be transformed into a globally accessible, standardised instructions manual, which can significantly contribute to minimising human error during daily operational tasks on ships.

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.

Opis:
Following the entry into force of regulations limiting emissions of sulfur dioxide into the environment for maritime vessels (Directive 2012/33 / EU), units engaged on voyages including in the Baltic Sea have been obliged to apply technical solutions are environmentally friendly.In this paper, shows the technological solutions that can be used in maritime transport to reduce emissions of sulfur oxides. Among other things, shows the types of scrubbers, how they work and sample costs associated with their operation. Moreover, presented the possibility of using LNG as a marine fuel. Finally visualized existing, planned and proposed station locations for fuel bunkering LNG ships in the Baltic Sea. As part of the research, analyzed, among others, the average price of marine fuels, with particular attention to low-sulfur fuel.
W związku z wejściem w życie przepisów ograniczających emisję tlenku siarki do środowiska dla statków morskich (dyrektywa 2012/33/UE), jednostki uprawiające żeglugę m.in. w rejonie Morza Bałtyckiego zostały zobligowane do zastosowania rozwiązań technicznych przyjaznych dla środowiska. W niniejszej pracy przedstawiono rozwiązania technologiczne, które mogą być wykorzystywane w transporcie morskim do redukcji emisji tlenków siarki. Przedstawiono m.in. rodzaje skruberów, zasadę ich działania oraz przykładowe koszty związane z ich eksploatacją. Ponadto zaprezentowane zostały możliwości wykorzystania LNG jako paliwa żeglugowego. Finalnie zwizualizowano istniejące, planowane i proponowane lokalizacje stacji do bunkrowania statków morskich paliwem LNG w rejonie Morza Bałtyckiego. W ramach przeprowadzonych badań, przeanalizowano m.in. średnie cen paliw żeglugowych, ze szczególnym uwzględnieniem paliw nisko siarkowych.

Opis:
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.
Artykuł przedstawia analizę możliwości udziału Polski w utylizacji niebezpiecznych substancji chemicznych w oparciu o doświadczenia duńskiej operacji pod kryptonimem RECLIB. W artykule przedstawiono sposób realizacji przez Królestwo Danii jednego z elementów polityki zagranicznej na przykładzie przeprowadzonej w 2016 r. operacji pod kryptonimem RECLIB, której głównym celem było usunięcie z Libii niebezpiecznych substancji chemicznych. Opisany został proces przeprowadzenia morskiej operacji pod przewodnictwem Danii przy jednoczesnym prowadzeniu aktywnej polityki międzynarodowej, w tym na forum Rady Bezpieczeństwa ONZ. Zaprezentowane zostało również współdziałanie Danii z innymi państwami, dla których przeciwdziałanie proliferacji broni masowego rażenia, zwłaszcza pod auspicjami Organizacji Narodów Zjednoczonych, stanowi wysoki priorytet w polityce zagranicznej. Omówione zostały także polskie, szerokie doświadczenia z zakresu utylizacji broni chemicznej i podjęto próbę zdefiniowania krajowych zdolności do usunięcia broni masowego rażenia z innego państwa w ramach operacji morskiej. W tym celu Autorzy przeanalizowali zdolności z zakresu obrony przed bronią masowego rażenia (OPBMR) i możliwości Marynarki Wojennej RP w zakresie transportu substancji niebezpiecznych z wykorzystaniem posiadanych jednostek bojowych.
