Opis:
In this paper a method for a ship safety estimation at the preliminary stage of design is briefly presented. Solving a few hydrostatic and dynamical problems may be taken into account using the method with special regards to the ships safety estimation in critical conditions. The critical conditions may concem the problems of survivability caused due to the cargo and/or ballast shift, waves and wind impact including the ingress of external water into the watertight compartments of a ship. The theoretical and computational models are briefly described. Using the computational model the safety assessment may be done for the initial event and scenario development assumed. Then, either some seakeeping, stability, damage stability or survivability related characteristics should be evaluated for the risk assessment. Both the seakeeping and stability characteristics are treated as the initial conditions for the risk assessment regarding the damage stability and survivability, and it usually follows from the hazard scenario development. The risk assessment is the base for the safety estimation. This is done according to the IMO regulations. The computational model incorporates the modern numerical techniques and is briefly described by introducing the logical structure of design system, logical structure of computational model and a few application methods used. The model enables to estimate the safety combining the influence of the hull form parameters, arrangement of internal spaces, loading condition including both the cargo distribution and permeability and impact of exciting forces. The exciting forces may follow from both the external and internal sources. And they are as follows: waves, wind and cargo and ballast shift.

Opis:
Strong expansion of cruise ships traffic and cruising destinations in the Adriatic makes the region ideal for cruise ships routing analysis. The aim of this paper is to detect real cruise ships traffic movement in order to understand how present cruise ships routes are navigationally and environmentally sustainable and safe. Cruise ships characteristic operational demand and navigational routine in relation with regions indented coast line with high level of environmentally preserved areas in landscape of high national value, emphasise importance of real cruise ships routing awareness. The research is based on one year cruise ships traffic monitoring and routes analysis in the Central Adriatic East coast. The results offer detail insight of cruise ships navigational routines in navigationally less defined area that has not been frequent cruising region before. Cruise ships routes comparison is carried out between North Adriatic region, which is well defined with traffic separation schemes and navigational aids and less defined Central and South Adriatic regions. The results show that principle of cruise ships routing differ from standard maritime practice and that operational demand for attractive cruising and passenger experience bring cruise ships close to shores in various demanding navigational situations. That routing practice does not meet criteria of sustainability as it often present high navigational, safety and environmental risk.

Opis:
In recent decades, there has been noticed a continuous growth of passengers on cruise ships. Technical as well as technological development follow this growth side to side as far as construction, transport of passengers and strict legal regulations are concerned. However, recent maritime accidents, such as the Costa Concordia’s accident, question the level of maritime safety on cruise ships. Maritime accidents on cruise ships are almost entirely linked to human factor, directly or indirectly. Apart from the parameters affecting human factor, the literature mentions very frequently the importance of education, training and crew competences in the process of reducing the number of maritime accidents. However, very few researches have been done on competences that can affect strongly the level of maritime safety on cruise ships, i.e., that can reduce the effects of human factor on it. The purpose of this study was to find a connection between reducing the effects of human factor on accidents and the crew competences on cruise ships. The research lasted for two years and consisted of two phases. Qualitative as well as quantitative methods of analysis were used in both phases. Competences that are the essential part of obligatory programmes the crew members on cruise ships have to master, and that are prescribed by the STCW Convention were analysed in the first part of the research. The second part of the research analysed competences that are essential part of programmes resulting from the cruise companies’ demands. Cruise companies have defined and determined additional programmes and competences that seafarers, navigating on their ships, have to complete and develop. The aim of the research was to determine what type of competences the cruise companies look for through additional education programmes and to determine the amount of time needed to develop them.

The efficiency of the thrusters is a predominant factor for the successful and economical operation. Forecasted development and rise of quantity of diesel-electric propulsion (it means with electrical transmission) would cause increased interest of unconventional thrusters. Ultimately they may revolutionize ship propulsion systems.

Opis:
The propulsion system of multi-mode ships cause many problems of proper the choise of propulsion system elements and theirs arrangement in the design process. This system has to fulfil at least two inverse demands. It ought to make possible efficient ship shift (transit mode) from the port to the off shore work place and return to base, to ensure a ship survive at sea in the worst sea condition possible on that sea area and to fulfil conditions of dynamic positioning accuracy (stationkeeping mode) at specified bad state of the sea - not to stop the ship work for long time. The dynamic positioning systems require multi-element ship propulsion application. The fulfilment, all required possibilities and accuracy of ship positioning by chosen propulsion system specified in the project data, is the most important project problem to obtain the minimum investment costs. The redimensioning of propulsion system, increasing the number of thrusters and theirs possibilities gives the benefits in dynamic positioning accuracy, but increases the investment costs. An expensive project may not be realized because of price. The aim of designer is the choice optimum solution of propulsion system, which is fulfils all expectations of ship owner and crew, and performs all project assumptions.

This paper contains formulation of a parametric method for evaluation of SWATH ship’s hull resistance. The method was elaborated on the basis of numerical calculation results obtained by using structural methods based on ship hydrodynamic theory and performed for sufficiently large series of body forms with systematically changing ship form parameters. Also, results of verifying investigations dealing with features of the method in question are presented by comparing the obtained resistance characteristics with those achieved by other authors as well as with ship model experimental test results. The obtained results of the verification indicate that the elaborated method can be useful in preliminary designing the SWATH ships.

Opis:
Power requirement for ship's movement depends on their size (water displacement) and sailing speed. The problem is especially important for fast ships, because the speed of movement is generating significant high power requirement, while limited displacement, diminishing a drag quantity from one hand, is a reason of limited draft and consequently limited capacity of a hull from the other. Above facts have strong influence at a number, type, power and size of main engines and propellers. Fast ships are designed for reaching maximum speed, but majority of exploitation time, are cruising at lower speed, called partial speed. That exploitation profile requires stopping of some engines or braking of propellers. Not driven propellers are dragged behind the hull, and work at a turbine mode, giving a torque at a propulsion shaft and creates a negative thrust what means the additional drag. The additional drag of not driven propellers must be calculated during the propulsion design stage, and analysis of speed value during different variants of the ship's movement . Torque values and thrusts can be evaluated basing on the universal hydrodynamic characteristics of propellers. the method and example of calculation of the drag created by free-rotating and stopped propellers of the exemplary propulsion set are presented in the paper.

The dynamic positioning systems require multi-element ship propulsion application. The chosen solutions have decisive effect on propulsion system possibilities, in ship dynamic positioning accuracy also. The automation system has an essential influence on it, because it is an integral part with propulsion system mponsible for this process. The most often ship propulsion solution based on unconventional thrusters driven by electric motor s also. A few independent propulsion systems is essential but it complicates this system, it is limited the number (most often to 4, seldom more up to eight). There are no solutions with traditional rudder and steering gear. These functions take over azimuthing thrusters because they can generale directional thrust force. It must be settle the question of the number of thruster choose and the span angle of azimuthing (most often by thruster turning). In that case it gets the possibilities of ship positioning, they may display as propulsion system characteristics, giving a view on ąuality of positioning process. The last veriflcation is made in real sea conditions when it may test if chosen solution of ship propulsion system fulfils the requirements of positioning accuracy. It was presented the examples of multi-mode ship propulsions and parameters of theirs propulsion plants.

The paper presents general rules of utilization of database, called „significant ships list,” for preliminary design of ship’s propulsion and configuration of power plant. Knowledge collected in the database is related to new buildings classified according to type, displacement, shipping class etc. It encompass general dimensions, characteristics of mobility ,propulsion’s power and type of main engines and propulsors, electric power plant, boilers and main mechanisms of a power plant. In the paper is presented method of utilization of the significant ships list during design of a container ship with capacity of 1300 TEU and speed of 18 knots. The first step of propulsion and main engine’s selection is determination of main dimensions, i.e. displacement, length, draft and breadth. That dimensions cannot be selected random way, due to hull’s mobility, stability and durability constraints. The list of significant ships consisted of 30 units, and amongst them, 17 were selected and analyzed. Others were rejected because of significant difference from mean values what could be due to different class of the ships.

Opis:
The article presents the problems related to the application of alternative fuel like solid biomass in the shipbuilding. The decreasing resources of the crude oil, the requirements regarding environmental protection as well as the increase of the liquid fuel prices were the reason for the study. The solid biomass comparing to the liquid or gaseous forms has relatively low calorific value. In order to increase this value the solid biomass is subject to the densification or torrefaction process and most often occurs in the shape of pellets. In this form it could be useful on ships. A test stand has been characterised where it can be experimentally verified whether ship’s rolling does affect the changes in flow resistance values during the pneumatic transportation of solid fuel from the storage facility to the boiler. On the basis of the measurements the hydraulic characteristics have been provided for the piping located on the movable platform with and without granular material. The changes in the platform oscillation period have influence on the change in the pressure inside transport piping for each investigated material. The results also show that the platform constantly inclinations do exert an influence on the pressure drop in the transport pipeline during transporting the granular material. It is smaller when the position is inclined. Comparing the results obtained for the different transported materials of a similar nature of the pressure fluctuations could be observed.

These issues constitute the substance of the ship’s navigation process and all its sub process. The authors’ belief is that the specification of these issues would enable the better understanding the matter of ship’s navigation process. It could also facilitate the preparation of more precise algorithms of all navigation sub processes, i.e. even those which hardly could be expressed by the means of mathematical relations.

In order to assess navigational safety on the basis of data obtained from AIS system, were prepared probabilistic domains of ships, which made it possible to estimate number of navigational incidents as well as their spatial distribution , that consequently allowed to determine potentially dangerous areas. The next phase was formulation of a simulative model intended for the calculating of probability of collision between the ferry and chemical tanker as well as the determining of characteristic scenarios for such collision. This paper presents also an analysis of consequences of the collision with taking into consideration a damage of cargo tanks.

Social responsibility in museums is not an entirely new domain. For many years now activities locating museums among the institutions contributing to creating better social reality have been observed. This new paradigm overcomes the stereotypical perception of cultural institutions as organizations taking care only of tangible and intangible testimony to the past of mankind, at the same time imposing on them the responsibility versus society and the community. The National Maritime Museum (NMM) in Gdansk tries to face these challenges not only by implementing educational and conservation projects, but also by supporting the development of the very Museum and its branches, at the same time directing its activities towards engaging in important social issues, such as eradicating accessibility barriers to heritage facilities, care for the environment, and sustainable development. Among the most recent accomplishments described in the paper let us mention the projects implemented during the COVID-19 pandemic, such as the new visiting format presented on the ‘Dar Pomorza’ Museum Ship. On 11 May 2021, NMM shared with the public the so-called Interactive Spherical Video integrated with modern Oculus goggles, introducing the spectator into interactive augmented reality allowing to become acquainted with the sailing ship from a new perspective, accessible to visitors with impaired mobility. A similar solution, though amidst a different landscape, was proposed in the lobby of the Museum’s main building on Ołowianka Island in Gdansk. Without getting aboard the ‘Sołdek’ Museum Ship, we can peep into its cargo hold and engine room. Furthermore, the paper describes many interesting educational or advertising undertakings which attempt at facing contemporary social challenges.

The current worldwide research on atmospheric pollution caused by emission of toxic compounds from marine engines is based on a simplified input data. Existing databases of emission of toxic compounds in exhaust gases of vessels navigating in various parts of the world could not be used to estimate the emissions in the meso and micro scale such as the Baltic Sea or the Bay of Gdansk, because it leads to over-generalization of emission indicators, mainly due to lack of required detailed traffic characteristics. The article presents the methodology of identifying the marine engine load to determine the indicators and characteristics of the emission of toxic compounds in the exhaust gases from tankers navigating to the Liquid Fuel Terminal in Gdansk. Course of action presented for modelling the characteristics of toxic emission of marine Diesel engines of main propulsion. It the range of indispensable analytic works will be describe to defining on basis on ships' resistor profiles, the profiles of load, helical, speed of navigation based on the parameters of movement ship gain over with system AIS.

collision risk among multiple ships
Opis:
To reduce crewmembers’ error and increase the safety of ships’ navigation, a recognition system of collision risks among multiple ships is newly-developed. By using ships’ navigational information such as AIS data, an algorithm to calculate collision risks among multiple ships is newly-designed. Collision risks of multiple ships can be estimated considering ships’ position and course of now and future by using fuzzy algorithm. To evaluate the performance of new system, replay simulation is carried out by using actual AIS data of actual collision accident in Korea. In this paper, main features of the monitoring system of collision risks and the results of replay simulation are discussed.

Thrust allocation system combines the work of an automatic control system with the ships actuators. On the basis of values of transversal and longitudinal forces and yaw moment determined by the regulator, it specifies commands for the individual thrusters located on board. A modified power distribution system, which takes into account the efficient work of a main engine propeller, is presented. During the research computer simulations were made on the basis of a modified and an unmodified thrust allocation system working with an LMI controller and a mathematical model of a training tanker. “Proposed method” of power distribution results in more efficient work of the controller and guarantees faster determination of the fixed velocity value.

Opis:
The paper presents the preliminary information on the concept of open water model tests for assessment of safety of ships in damaged conditions. The need to develop the concept follows from the fact that the current regulations for assessment of safety of ships in damaged conditions require to consider an influence of many factors coming from different sources. Among the most important factors are those which come from the ship itself and the environment. Of course, the current regulations take into account the impacts which follow from the stages of flooding and progressive flooding but not all the possible impacts are taken into account. The open water model tests may enable to verify the existing regulations and model some phenomena associated with flooding. The open water model tests can be an important alternative method for the assessment of ship safety. The current method and some elements of the new approach to the safety of ships in damaged conditions are briefly described in the paper. A concept of the open water model tests for assessment of the safety of ships in damaged conditions are introduced. Some details regarding the research stand are given. The preliminary programme of investigations is presented as well. Because of the limited space available in the paper more details regarding the concept of open water model tests will be given in the POWER POINT presentation during the Symposium and in the final version of the paper.

Opis:
The paper regards various design and operational problems associated with survivability of surface naval and merchant ships using an alternative probabilistic methodology. This methodology is based on application of the performance-oriented and risk-based approaches. The performance-based approach requires to use the design and hydromechanics-based application methods. A measure of a ship safety in damaged conditions is either a risk or risk level. The risk is estimated using the risk analysis. Between the most important elements of risk analysis are the hazard identification, scenario development, quantitative risk assessment and risk control. The assessment of safety is based on the total risk management TRM approach including the risk assessment and risk management. The detailed discussion regarding the method and modeling will be submitted for publication by the Gdansk University of Technology in separate publication.

Opis:
The berthing of ship to the quay is last stage of navigation process. An ideal manoeuvre would be consisted in a total loss of speed at the moment the ship makes contact with the quay. In practice, the ship has some speed, which caused the impact of ship in the quay. The accident can be happened when kinetic energy overdone the admissible value during contact the ship-quay. In results, the damage of ship's hull or port structure can occur. The fenders improve the safety of berthing operations by partially absorbing the kinetic energy of ship. The fenders parameters should be properly selected relative to existing condition during ship's berthing. It depends on effective energy of berthing ship. There are used some method to calculate of its value. One of them is based on phenomena of ship turning relative to point of first contact to the quay. Then the part of ship's kinetic energy is altered to work of turn, and in result, energy of ship impact is decreased. This part can be determined by coefficient of eccentricy. Its value mainly depends on radius of ship's turning, which is equal of distance between point of ship, gravity and point of first contact with quay. Simplified method of calculation the eccentricy coefficient based on ships angle of approaching to the quay. But such estimated value is weighted some discrepancy. The paper presents the analysis of methods of calculation the kinetic energy during first impact in the quay. Especially, the geometrical shape of ship's hull is considered to achieve the accuracy value of ship's impact energy during the berthing to the quay. The application of elaborated method permits to optimize the parameters of fender system.

Opis:
Seafarers working in the 21st century global shipping industry are multi-national crew of migrant contract labourers, recruited by crewing agencies to work on a variety of ships for specific periods of time. Types of ships found today may include bulk carriers, container ships, tankers, gas carriers, heavy lift vessels, car carriers, ferries and passenger ships such as luxury cruise liners, among others. The voyages undertaken on board ships cover an expansive global maritime environment depending on where the goods are sourced, the destination, goods being transported, the type of ship, and if there are any designated ports of call for loading and offloading goods as well as boarding and disembarking passengers on the way. Typically, the greater proportion of the seafarers’ contract period is spent at sea, working in a maritime work environment on board different ships where he is assigned by his employer. During this time, crew interact with colleagues from a variety of nationalities, performing role-specific tasks in the same built environment and within a maritime mobile workspace. While conducting an empirical research on ship crew in the international fleet to harness their views on how maritime piracy in Eastern Africa may be affecting their health and wellbeing, the author observed that the ripple effects of structural changes in the shipping industry in the last few decades could be adversely influencing the seafarer work environment and social interactions, in ways that justify the description by Lane and Smith (2011) of ‘ships as jails’. The author has analysed the social adjustments that seafarers constantly make in order to fit into their evolving mobile workplaces. This discussion has been done using ideas espoused form Goffman’s ‘Total Institutions’ conceptual framework. This article therefore seeks to discuss the acculturation process that crew undergo within their mobile work built environment, as being comparable to some extent, to the social adjustments that Goffman’s subjects underwent in their institutions. Through ‘mortification processes’, the residents in Goffman’s studies were impacted psychologically by the regimented social life in the enclosed institution spaces interacting within limited social circles. Although a number of aspects have been identified that have the potential to adversely affect seafaring occupational health and safety regime (Walters, Bailey, 2013), this article will concentrate on highlighting some factors within the seafarers work place that in the author’s opinion, have directly influenced some psychological adjustments that seafarers make, in order to adapt the seafaring culture befitting their workplace. Three noteworthy influential factors discussed in this article include(a) the cumulative effect of living and working in an enclosed built environment (b) the seafarers’ limited social circle while onboard ships (c) the physical and social isolation of seafarers from colleagues while on-board ships, and from their families and land-based communities by the ship structure and the geographical maritime nature of their workplace. These features were selected as they could be discussed from Goffman’s theoretical framework as possible influences on the seafarers’ workplace socialization process. They are just a few comparable factors between the situation of modern seafarers and Goffman’s subjects. The scope of this paper will explore the potential for these three key factors to impact on psychological adjustments that seafarers make during their career working on ships. The author has based the discussion of ‘Ships as Total Institutions’ on the fact that there exists evidence of the cumulative effect of each of these three factors over time in the career of seafarers. The empirical studies provide the evidence upon which the author concludes that the ship is a ‘Total Institution’. This article has been written as the drafting of the author’s thesis is at an advanced stage. The intention of this paper is not prescriptive, rather as a catalyst for discussion of seafarers’ work environment and occupational health and safety from an additional social theoretical perspectives.

Opis:
Ship noise is a most important part of the field of underwater acoustics. Its reduction and monitoring is an important aspect in the performance of underwater acoustic systems and in the habitability of the vessel for the crew and passengers. In naval operations the noise radiated by a ship is also dominant source of information for underwater sonar systems. Sound intensity is the vector quantity which informs us about the sound power flux, the position and the direction of the sound source. The probe tracks the position of source and at the same time, measures the component of sound-intensity vector. Generally only one component of vector sound intensity was measured, perpendicular to a given measurement surface. The sound intensity of a moving source includes effects such as flow noise that are not present when the source is stationary. The accuracy of measuring acoustic intensity using two closely spaced hydrophones by correcting the phase mismatch error by measuring the transfer function between the two detector systems was examined. The two measuring hydrophone instrumentation systems were earlier calibrated. Our results have been obtained using digital methods, where was used PULSE measuring system.

Opis:
Combined heat and power (CHP) is a facility which uses one energy source to produce both electricity and thermal energy at the same time. CHP has an advantage when compared to conventional power plants which produce only electricity or thermal energy because it is much more efficient - it minimizes the usage of its primary energy source, grid losses and greenhouse gas emissions. CHP’s big advantage lies in its applicability: it is highly compatible with existing technologies already in use in different power systems across the industry, agriculture, business and residential sector. This paper describes the cogeneration in general, its application, classification and characteristics. It also describes various cogeneration plants on board, their principle and the advantages and disadvantages of individual processes. This paper contains analysis of cogeneration systems and their comparison, especially on board ships. The paper uses results of other authors to analyze on board systems and to suggest optimal solutions for various ship types. The papers aim to became one of the tools for project engineers and operation engineers.

Opis:
The analysis of the historical aspect of the development of the maneuvering during anchoring shows that during the movement there is no time to control the position by technical means, due to the speed of the process of changing the parameters of movement. The main purpose of this research is to modify the methodological basis for the preparation of flight planning during anchoring with increased accuracy to determine the coordinates along which the ship will move. The methodology of this work is based on the calculation of trajectory points of the path in combination with the method of segments on the map using the characteristics of the maneuverability of the vessel. The method is based on determining the coordinate matrices of rectilinear and curvilinear sections through which the vessel passes during maneuvering for anchoring. The calculation program is developed in Excel, and allows without the help of a micro calculator that takes into account the maneuverability of the vessel in the automatic system. Thus, the control of the center of gravity of the vessel relative to a given path line is performed. A high-precision system for automatic determination of planned coordinates by trajectory points on track and traffic control during anchoring has been developed, which is based on recently developed algorithms, calculation schemes and methods at the Maritime University, which are based on the latest meaningful models of high-precision planning movement on them. This approach automates the process of controlling safe traffic, including the use of decision support systems, including stranding prevention and collisions with other vessels. The results of the research can be used on a ship for automated planning of coordinates on waypoints and control of traffic on them for safe maneuvering, as well as for training navigators on specialized simulators to perform trajectory planning, including limited conditions.

Opis:
Presented are regulations concerning the operation of passenger ships (with particular emphasis on Polish ferries) designed to increase maritime safety the SOLAS Convention, established in 1974 and codified in 2002, codifies these regulations, and the International Maritime Organization mandates additional regulations, created in response to a rapidly increasing number of maritime disasters. The analyses described herein were based on restrictions established for the “Jan Śniadecki” and “Mikołaj Kopernik” ferries. Safety of ro-ro units, which also typically have a significant number of people on board, was also analyzed. Also included in the study were ship operational- limitation characteristics with respect to structure, unsinkability, and stability of machinery and electrical equipment, fire protection, operational requirements, and rescue measures and devices, along with their purpuroses. Safety management consists of taking appropriate actions to prevent or minimize the effects of an accident or a disaster and is assessed on the basis of calculations and experience gleaned from analogous cases. Safety management can proceed if a problem has been thoroughly assessed. The potential risk of negative consequences with respect to the safety of the transport process as a whole must be considered, and the safety of the whole must not be risked for that of a particular part of it. A safety management decision can be made when its necessity is not in doubt. A problem is assumed to have only one solution. The effectiveness of the previously used method should be carefully assessed before proceeding to the next method. Security management is not easy and requires much professional knowledge and experience.

This paper is an extension of work originally presented in 2019 EUROPEAN NAVIGATION CONFERENCE (ENC) [4]. The paper has described the important role of the Stockholm Agreement in safety of the Ro-Ro/Passenger ships in the north European waters. The present work describes the way in which we can improve the safety in strong chance of destruction of ship at sea. All results are generalized for a given group of ships. The specific construction of the RO-RO/ Passenger ships, being characterized by flat vehicle decks which are practically open, un-subdivided, and additional passenger accommodation space, with ramp fitted astern and in some cases in fore or side of the ship, giving access to cars, trucks and trailers, or specific trains which remain on board in their laden state, has resulted in international regulation requiring, amongst other things, strengthening the damage stability requirements for this type of ships. The more stringent damage stability criteria has been adopted on a regional basis by northern European countries as STOCKHOLM Agreement, in 1996. The paper concerns an analyze of damage stability calculations results in compliance with the STOCKHOLM Agreement, when the Ro-Ro/ Passenger ship is fully loaded, with maximum Deadweight (DWT) and maximum draught, or partly loaded, with reduced DWT, and occurs Minor or Major penetration of destroyed compartments.

Introduction. The increasing development of marine traffic has led to a rise in the incidence of legionellosis among travellers. It occurs in similar environments, especially closed and crowded, and aboard ships Legionella survives and multiplies easily in water pipes, spreading into the environment through air conditioning systems and water distribution points. Although in recent years in the construction of cruise ships preventive measures aimed at curbing the proliferation of Legionella (design, materials, focus on the operation and maintenance of the water system), have been taken account, little or no attention has been paid to small ships which, in many cases, are old and not well maintained. Objective. The aim of the study was to evaluate the frequency and severity of Legionella contamination in ferries and cruise ships in order to adopt more specific control measures. Materials and method. A prevalence study was carried out on 10 ferries and 6 cruise ships docking or in transit across the port of Messina (Sicily, Italy). Water and air samples collected from many critical points were tested for qualitative and quantitative identification of Legionella. Results and conclusions. Legionella pneumophila sg 1 was isolated from the samples of shower and tap water in 7 (70%) of the 10 ferries examined, and in 3 (33%) of the 6 cruise ships examined, and L. pneumophila sg 2–14 in 8 (80%) and 1 (16.7%) of these ships, respectively. No Legionella contamination was found in whirlpool baths, air and ice samples. In conclusion, the data obtained confirm higher levels of Legionella contamination in local ferries and cruise ships, underlining the need to adopt corrective actions more specific for these smaller vessels.

Opis:
There is a need for developing improved methods of evaluating the safety of cargo ships that would quantify and assess the ship safety more comprehensively than current methods and further allow for a more direct comparison of ship designs safety-wise so that safety could become one of the goals of design process. This newly developed method will not only have to allow for effective determination of ship safety, but also should meet expectations from various industries. This paper presents an alternative approach to safety of ships in damaged conditions, which when further verified and evaluated, could serve as a useful tool for designers and ship operators alike. It was shown that a computationally efficient quasi-dynamic method that addresses the main drawbacks of current regulations can be formulated for evaluating the exact risk levels at any stage of vessel’s life.

The paper present the methodology of evaluations acoustics energy from the mechanisms of ship into the water environment. For that purpose the research of noise distribution over ship's hull were conducted along with the hydroacoustic field. The hull is source of waves of complex surface shape inducing waves of different amplitudes and phases depending on the position of ship's machinery. As a result of the hull vibrations generated wave distribution depending on the primary sources, as the main propulsion units, generators or other mechanisms. This research allowed to determine position of the main noises' sources of acoustics energy of machinery and propulsion system depending on class of ships.

This article has been hypothesized for the distribution of ships passing distances from which you can build a probabilistic domain. The article summarizes the studies for three types of ships: tankers, passenger ships and cargo vessels and is comparing the shapes of domains for each of them in three situations: overtaking, crossing, vessels on the opposite courses. Studies were carried out in the Gulf of Pomerania.

The paper presents a proposal of a method for the computation of ship’s deck elevation at any time and location on-board. The need for such a computation results from an interaction between a ship and cargo being loaded or discharged by a gantry in port, in terms of heeling and rolling of the vessel. The main purpose of such modeling is the need for improvement of gantry control with regard to faster operations thanks to more accurate estimation of level and moment of cargo release from a gantry hook or spreader. The study may be the contribution to the development of gantry control systems in sea ports.
W artykule przedstawiono propozycję metody obliczania chwilowego wzniosu pokładu statku podczas operacji ładunkowych w porcie. Potrzeba prowadzenia takich obliczeń wynika ze wzajemnego oddziaływania ładowanego ładunku na statek i odpowiednio – statku na proces załadunku. Statek doznaje bowiem zmiennego w czasie przechyłu wskutek umieszczenia na pokładzie bądź w ładowni dowolnej masy, np. kontenera. Zasadniczym celem opisywanych obliczeń jest poprawa dokładności sterowania suwnicą kontenerową poprzez wyznaczenie chwilowego poziomu pokładu w miejscu przeznaczenia każdego ładowanego kontenera i dalej – precyzyjne określenie wysokości i momentu ustawienia kontenera. Przeprowadzone badania mogą się przyczynić do rozwoju systemu sterowania suwnicami w portach morskich.

Opis:
There are different approaches to risk assessment. The SOLAS Convention is the most important safety instruments at maritime transport. The biggest risk is a major navigational incident because it can result in fatalities and pollution. Possibly the major cause of collision incidents is not fully understanding and complying the COLREGS rules. It is not possible to create a simple flowchart to define a suitable approach to risk assessment of a ship. However, some of broad factors can be used to aid the selection of a suitable risk assessment approach in maritime transport. In the literature, we can find many methods and applications for maritime transportation risk analysis. There is a recent focus on foundational issues in risk analysis, especially for intensified research on fundamental concepts and principles. This paper presents the attempt of applying the Bow-Tie methodology at maritime transport. The benefits of using Bow-Tie diagrams for risk assessment have been showed at use, for many of technical systems and processes. This methodology known as barrier diagrams, provide a readily understandable visualization of the relationships between the causes of the failure's event, the escalation of such events to a range of possible outcomes, the controls preventing the event from occurring and the preparedness measures in place to limit the consequences. The Bow-Tie is very useful for structured assessment and communication of risks.

This paper analyzes the requirements of the information transmission network of ship integrated condition monitoring system, and proposes a design scheme of ship condition monitoring system based on wireless ad hoc network. The wireless ad hoc network protocol was designed, its networking process was analyzed in detail, and the network transmission performance of the monitoring system was tested. The results proved the feasibility of the system. The above solution can be used for the transmission of ship state information that satisfies the requirements of wireless transmission, and has important theoretical and practical significance. The slot allocation algorithm has been receiving extensive attention as an important part of the TDMA system research. This paper analyzes the summarization and summarization of TDMA time slot assignment algorithms from several aspects such as slot synchronization, existing slot allocation algorithm, and slot assignment model, laying an important foundation for researchers to do further research. In the TDMA system, time is divided into non-overlapping time frames, and the time frames are divided into non-overlapping time slots. Each node in the network performs corresponding operations in each time slot.

Opis:
Robust path following control for underactuated surface ships is an important issue in marine control practice. This paper aims to improve the robustness of the close-loop system with model uncertainties and time-varying disturbances. A practical adaptive backstepping control scheme with a pre-filter is proposed to force a surface vessel to track the predefined path generated by the virtual ship. Based on the Lyapunov stability theorem, this algorithm can guarantee all error signals in the overall system to be uniformly ultimately bounded, and it can be implemented without exact knowledge of the nonlinear damping structure and environmental disturbances. The proposed pre-filter can smooth the commanded heading order and obtain a better performance of the waypoint-based navigation control system. Two simulation cases are drawn to illustrate the validity of the proposed control strategy.

In recalculation of a model resistance into a real object resistance, one of difficult to estimate values is the shape coefficient. There are well known and tested methods of determining the (1+ko) coefficient for sea-going ships. In the case of inland vessels navigating in the limited depth waterways the problem has not been solved completely. The paper presents results of computations of the inland vessel shape coefficient determined by means of numerical methods (MOS). The shape coefficient has been calculated as a function of the block coefficient and block coefficient of the forebody of a barge hull. The calculations were based on five typical shapes of the transport inland vessels and were carried out for different depth to draught (h/T) ratios and different sailing speeds.

Opis:
This paper typically applied the concept of ranking by inspection using the dwell time of ships in five African ports to evaluate the variations in ship turnaround time and relative efficiency level. This is to identify the active factors that cause port congestion in African ports. The results provided some explanations on the consequences arising from these on notable African logistics and supply chain networks. The findings reveal that the bane of congestion in African ports emanates entirely from either planning, regulation, capacity, efficiency or a combination of these. The regression analysis with IBM SPSS v20 reveals that there is a significant relationship between cargo throughput and other port performance indicators in Nigeria for the study period (2005 - 2014). More so, the t-test reveals that there is a significant relationship between cargo throughput and berth occupancy rate which is significantly indicative of port congestion. This paper therefore recommends that African ports should enhance their regulatory mechanisms, and also improve capacity and efficiency level in order to shoulder the ever increasing challenges of port congestion in years ahead.

Opis:
The paper presents a discussion on the strength criteria and load cases required in the rules of classification societies for direct FEM strength analysis of ship hull structures, which show some differences to each other. The conclusion of it is that detail studies on stress values in ship structures are necessary to improve the requirements. With this end in view an effective method for long-term prediction of stresses in ship hull structure princiŹpal members is proposed. The method is based on the concept of influence coefficients and spectral analysis of wave loads. A FEM model of the principal member system in the form of 3D frame is applied to calculate values of the influence coefficients. Next, the concept is used of correlaŹtion factors for combining characteristic long-term stress values caused by global and local loads, with combined stresses due to general bending of the ship, zone bending of the principal members and local bending of longitudinals. As an example, results of stress prediction and correlation factors calculated in some points of hull structure of a panamax bulk carrier are presented and discussed.

Opis:
Po wielu latach od przyjęcia w 1982 roku konwencji o prawie morza, u progu XXI wieku zyskała ona niemal pełną i powszechną aprobatę społeczności międzynarodowej. Ciągle jednak można dostrzec liczne przykłady rozbieżnych interpretacji jej postanowień. Jest to doskonale widoczne na przykładzie ośmiu państw bałtyckich, które ratyfikowały konwencję, a jednocześnie niektóre z nich utrzymują prawo krajowe pozostające w wyraźnej sprzeczności z jej normami. Dotyczy to szczególnie kwestii „reglamentowania” przepływu okrętów obcej bandery przez morze terytorialne i cieśniny międzynarodowe (poprzez wymogi notyfikacji, korzystania tylko z wyznaczonych szlaków morskich i uzyskania zezwolenia). W artykule podjęto ten problem, poddając analizie rozwiązania przyjęte we wszystkich państwach bałtyckich i NATO.
At the beginning of the 21st century, many years after the convention on the law of the sea was adopted in 1982, it has gained almost universal recognition of the international community. Still examples of different interpretations of its clauses can be noticed. This is clearly visible in the case of the eight Baltic states, which ratified the convention, but some of them have still in effect the national law which is in contradiction to some clauses of the convention. This pertains mainly to the issue of „rationing” the passage of ships, displaying foreign ensign, through the territorial sea or international straits (by requiring notification, using assigned waterways and obtaining permission). The paper deals with this problem, analyzing the solutions adopted in all the Baltic and NATO countries.

Opis:
This article analyzes some maritime accidents involving passenger ships that occurred in the Baltic Sea. Existing forms of passenger transport by sea have been identified, and passenger-ship accident statistics in the years 2003 to 2013 are presented. We discuss threats that may exist in passenger transport such as, technical, operational and navigational risks, as well as threats caused by human error and bad weather. In the last part of the paper, we analyze the cause and effect of selected incidents of passenger ships in the Baltic Sea, which include the grounding of the ship MS Amorella, the Stena Spirit ferry collision with infrastructure, and the collision of two ships, the MS Gotland with HSC Gotlandia II. The impact of the human factor on the safety of passenger ships is also analyzed.

Opis:
Preliminary ship owner's assumptions for new ship consist of deadweight, speed-shipping line and others. Taking it as a base, in early stage of design one has to select propulsion type. This goal needs definition of principal dimensions of a vessel, which are the base for further calculations of hull’s resistance and evaluation of necessary power of main engine to fulfil shipping requirements. Selection of main dimensions of vessel is limited by rules regarding buoyancy, stability, hull strength, manoeuvring capability, and limitations related to seaways or harbours characteristic. In this article is presented the methodology of calculation of principal parameters of a vessel, necessary for calculation of displacement in relation to vessel’s type, volumetric coefficients, Froude number, and others values affecting ship’s dimensions. It is about midship section coefficient, waterline coefficient, prismatic coefficient. Those values are necessary for calculation of hull resistance. In the article, are presented major constraints for designing of new vessels coming from ship-owner assumptions such as seafaring limitations. In the table is presented comparison of results of calculations above-mentioned values of three type of vessels representing same displacement. There are also presented different calculation methods of transverse midship section coefficient and wet area coefficient, for 3 types of vessels (container vessel, bulk carrier and tanker with displacement of 120000 t.

This paper aims to show a practical case study of safety assessment concerning possible injuries and fire occurring in the engine room on-board a merchant ship, due to fatigue. Methods The methodology was centred in literature hazard identification, measurements in real ships and heat stress indices definition. Results Some corrections are proposed in order to obtain a safe environment for workers in the engine control room and to prevent fatigue risks at the engine room. This will allow adequate oil leakage detection and, as a consequence, improve fire prevention. Discussion Training is a preventive control option, but this study allows the understanding of new corrective control options like design corrections.

Opis:
The presented work is a contribution to discussion on usefulness of application of measurement instrumentation used on sea-going ships for energy measurement and scientific research purposes. Contemporary sea-going ships are equipped as a rule with up-to-date measurement instrumentation usually based on electronic data processing and computer technique. These authors have made many times use of such instruments in their research work. This way it was not necessary to install any special instruments, that significantly reduced measurement cost. In such cases to obtain a sufficient accuracy of measurements constitutes a crucial problem. In this paper was presented an analysis of measurement errors of some operational parameters of ship and its main propulsion system, elaborated within the frame of the KBN research project no. 9 T12D 033 17. Results of the analysis confirm usefulness of the standard measurement instrumentation installed on ships, and its sufficient accuracy.

Opis:
Ship traffic is one of the factors that is presented in almost all of the existing grounding models, and is considered as one of the affecting factors on the likelihood of grounding accident. This effect in grounding accident is mostly accepted by the experts as a common sense or simply by just generalizing the ship‐ship collision cases to grounding accidents. There is no available research on the actual causal link between the ship traffic and grounding accident in the literature. In this paper, authors have utilized the statistical analysis on historical grounding accident data in the Gulf of Finland between the years 1989 and 2010 and the AIS data of the same area in year 2010, as the source of ship traffic data, to investigate the possible existence of any correlation between the ship traffic and the grounding accident. The results show that for the studied area (Gulf of Finland) there is no correlation between the traffic density and the grounding accident. However, the possibility of the existence of minor relation between the traffic distribution and grounding accident is shown by the result. This finding, however, needs further investigation for more clarification.

Opis:
Modern industries often attempt to implement innovations that have a disruptive potential. In shipping, this included a largely unsuccessful introduction of nuclear propulsion in late 20th century, among other concepts. Nowadays, introduction of increased autonomy is being associated with prospects of various industry-wide benefits, but is also burdened with serious obstacles. The objective of this study is to investigate reasons behind the failure of nuclear-powered merchant ships introduction and whether lessons learnt from it can be applied to the prospective implementation of autonomous merchant ships. It advocates that three aspects of maritime technology are crucial for its successful implementation: perceived level of safety, economical feasibility, and legal setup.

The article presents and evaluates the technical and operational possibilities of the maritime radio communications systems to be used especially for the exchange of information between the land users and ships. The basic functional requirements and regulations for Global Maritime Distress and Safety System (GMDSS) referring to the maritime radio information systems, resulting from the provisions of the International Convention for the Safety of Life at Sea (SOLAS) and Radio Regulations have been described. The article presents the role of information systems in the shipping and GMDSS as well. A current status of the maritime radio communication systems responsible for the exchange of information between the land users and ships has been presented. Operational and technical characteristics of the maritime radio systems used for the exchange of safety information and ships’ operating information have been described. The analysis of the systems responsible for broadcasting to the vessels the Maritime Safety Information (MSI) has been made. In this context, the operation, methods and ranges of broadcast of the Maritime Safety Information by the NAVTEX system and Inmarsat SafetyNet system have been discussed. The analysis of the systems responsible for the ships’ operating communications has been made too. The article also outlines the future of maritime radio information systems. In this context, two projects currently being implemented in the framework of the International Maritime Organization (IMO) by the Sub-Committee on Navigation, Communications, Search, and Rescue (NCSR) have been presented. The first of these projects under the name of e-Navigation refers to the use of the latest information and communication technologies in shipping. The second one concerns the modernization of the GMDSS. It is expected that as the outcome of these project works, among others, new maritime radio information systems presented here will be adopted.

Currently, the Baltic Sea States suggests a proposal to designate the Baltic Sea as an Emission Control Area for nitrogen oxides, in accordance with Annex VI of MARPOL73/78. The emission would be estimated on the data produced by the AIS (Automatic Identification System) system that is compulsory for ships. Therefore, exhaust emission of the ships' can be computed using the actual speed and main propulsion shaft power. Mostly, main propulsion engines' exhaust emission is dependent to realistic performance and can be determined. The research plan has been prepared, aimed an evaluating the main propulsion engine performance and emissions. In cooperation with the ship owner, the experimental program onboard the container vessel, equipped with latest large bore, two-stroke, and slow speed MAN B&W electronic controlled engine was carried out. The records set of vessel speed and related engine shaft power, fuel consumption and exhaust emission for container vessel is formed. Taking into account; main engine performance, types of fuel and other input data, the emission factors were determined for ship sea service state. Main engine shaft power estimation and measurement setup, examples of main engine shaft power, the shaft power equation coefficients density, example of main engine service operation, fuel oil consumption group, the ship speed estimated form, example of main engine area operation influenced by weather conditions are presented in the paper.

Opis:
TEU number which the container ship is designed for, directly influences the main hull dimensions that is displacement D, length L, breadth B, draught T, their combinations and block coefficient delta. The main dimensions have a great impact on developing the ships resistant performance. Thus, it is really fundamental to establish the correct dimensions of the hull during the design and ship building process. Estimating the shape of the ships hull, that comprises its main dimensions, is one of the basic tasks as part of the preliminary design stage. The most significant decisions determining ships performance, its duration and building costs are made at the beginning of the preliminary stage, before the contract is signed, when the costs are relatively low, up to 4.5% of total costs of technical and working stage. The results of the decision that has been made at the preliminary design stage are significant for the new building ship including its building costs and what is more important, for the ship owner, the ships operational costs. It is important to limit the total ship resistance, for instance, by lowering the wave ship resistance as much as possible, especially when the operational speed and TEU number carried by one vessel is increasing. That resistance depends on the operational speed expressed by Froude number. The resistance criteria and the existing hull dimensions limits, resulting from ships route, must be taken into consideration bearing in mind safety conditions such as ships stability and seaworthiness, when the main ships dimensions are being determined.

Opis:
The article proposes valuating the operation of an arbitrary diesel engine, based on the sample case of a ship’s main engine in which energy conversion processes take place in a given time. The above operation is understood as the energy transfer to the screw propeller in the given time in which the energy conversion into work and/or heat and its further transmission take place. The here proposed method for evaluating the operation of the main engines installed in marine power plants consists in comparing the operation of these engines to a physical quantity the measuring unit of which is the joule-second (joule×second). A new term is introduced which bears the name of the theoretical engine operation and is the standard (ideal) operation which can be compared to the operation of real engines revealing different levels of wear. It was shown that the calculations of the theoretical operation defined in the above way cannot make direct use of commonly known theoretical Diesel and Sabathe cycles. Instead they should use the cycles modified by heat abstraction taking place in accordance with the isobaric, or isothermal process. Other new terms introduced in the article are: the degree of excellence of energy conversion to work, considered as the measure of excellence of engine operation, and the degree of engine operation dissipation, being the measure of its real operation. It is shown that if in time t of engine operation the case takes place that: Li = idem and Le = idem, then the engine operation dissipation is equal to its mechanical efficiency.

Opis:
Multi-energy hybrid ships are compatible with multiple forms of new energy, and have become one of the most important directions for future developments in this field. A propulsion inverter is an important component of a hybrid DC electrical system, and its reliability has great significance in terms of safe navigation of the ship. A fault diagnosis method based on one-dimensional convolutional neural network (CNN) is proposed that considers the mutual influence between an inverter fault and a limited ship power grid. A tiled voltage reduction method is used for one-to-one correspondence between the inverter output voltage and switching combinations, followed by a combination of a global average pooling layer and a fully connected layer to reduce the model overfitting problem. Finally, fault diagnosis is verified by a Softmax layer with good anti-interference performance and accuracy.

A model is developed for studying marine traffic flow through classical traffic flow theories, which can provide us with a better understanding of the phenomenon of traffic flow of ships. On one hand, marine traffic has its special features and is fundamentally different from highway, air and pedestrian traffic. The existing traffic models cannot be simply extended to marine traffic without addressing marine traffic features. On the other hand, existing literature on marine traffic focuses on one ship or two ships but does not address the issues in marine traffic flow.

Opis:
The study presents the evaluation and comparative analysis of engine shaft line performance in maritime transport ships of the same type. During its operation, a technical system performs functions for which it was designed. It goes through different states. Dynamic state changes of a rotational system can be identified by means of its vibration measurement. For this purpose, a research was carried out which involved recording vibrations of the analysed rotational systems. The recordings were used for calculating selected characteristics in the time-domain, where one of the most unique is the value of the normalized mutual correlation function. On the basis of the concentration values, the characteristics which unambiguously determine the ability state were selected for further studies. Then an identification method for rotational system non-coaxiality was proposed. The method involves using fuzzy clustering. According to this method the values of input signal characteristics were used to formulate fuzzy clusters of system ability and inability states. The method can be used for identifying the current state of the system. The study presents the results of the application of this method in engine turbine shaft lines of minesweepers, with the rotational system selected as an example. It needs to be noted that the efficiency of identifying the operating state of the system with this method is higher than with other methods described in the literature by authors who deal with this issue. The research results have a significant impact on the evaluation of mechanical properties of the studied objects and directly affect operational states of mechanical systems, including those installed in minesweepers, thus determining their reliability.

Opis:
This paper concerns an algorithmic method for preliminary selection of parameters of ship propulsion system fitted with fixed screw propeller in the case when the ship’s operation is associated with significant changes of waterway depth and width, hull resistance of the ship and its service speed. Mathematical model arguments of the considered design problem are main ship design parameters identified in the preliminary design stage. Structure of the formulated model complies with formal requirements for continuous- discrete mathematical optimization problems. The presented examples of application of the method concern an inland waterways ship fitted with compromise screw propeller optimized in the sense of minimization of fuel consumption for passing a given route distance within a given time. The elaborated method may be especially useful in designing such ships as : coasters, inland waterways ships, tugs, pushers, trawlers, mine sweepers, icebreakers etc.

Opis:
Bezpieczeństwo i higiena pracy na statkach żeglugi śródlądowej wynikają ze specyficznych warunków pracy, odbiegających od lądowych. W zależności od realizowanych zadań eksploatacyjnych oraz wielkości i stanu technicznego jednostki, czynniki uciążliwe i szkodliwe to przede wszystkim hałas, wibracje, oddziaływanie temperatury, a także znacznie ograniczona przestrzeń, zarówno na stanowiskach pracy, jak i w pomieszczeniach socjalnych. Pracę na jednostkach żeglugi śródlądowej charakteryzuje również specyficzny rozkład czasu pracy. Ze względu na fakt, że wiek większości jednostek żeglugi śródlądowej przekracza 50 lat, do problemów bezpieczeństwa pracy powinno przywiązywać się szczególną wagę. Warunki pracy w dużej mierze zależą od starań właściciela jednostki oraz od kultury pracy załogi, a powinny być także wyznaczane wymaganiami przepisów. Problem w tym, że obecnie obowiązują jedynie wymagania dotyczące czasu pracy na statkach żeglugi śródlądowej. Szczegółowych przepisów dla załóg statków żeglugi śródlądowej, dotyczących bezpieczeństwa i higieny pracy na zróżnicowanych stanowiskach pracy, nie ma od 2002 r. Ta luka w polskim prawie wymaga możliwie najszybszej interwencji.
Occupational safety on ships during inland shipping is a complicated subject due to particular working conditions, quite different from those on land. Depending on the tasks carried out, the size and the technical state of the inland shipping ships, harmful and onerous factors include noise, vibrations, high or low temperature, as well as limited space of both workplaces and social rooms. The work on the inland shipping ships is also connected with the particular work time distribution. Since the age of the majority of inland shipping ships in Poland exceeds 50 years. Occupational safety is a very serious issue. Working conditions largely rely on the owner’s due diligence and the crew's sufficient work culture, whereas they should also come from suitable regulations. The problem is that currently only work time distribution is regulated via Legal code m relation to work on inland shipping ships. Since 2002 there have been no detailed regulation concerning. Occupational safety towards crews of the inland shipping ships. This gap in the Polish regulations seems to be a problem requiring a fast reaction.

Opis:
Recykling statków wycofanych z eksploatacji, stanowiący ostatnie stadium cyklu ich życia, może nieść poważne zagrożenie dla bezpieczeństwa ekologicznego i zdrowia pracowników, z uwagi na stosowanie nieodpowiednich technologii i procedur w stoczniach złomowych, zwłaszcza tych zlokalizowanych na subkontynencie indyjskim, a także ze względu na obecność wielu substancji niebezpiecznych w konstrukcji i wyposażeniu statków. Skierowanie uwagi świata na skalę problemu zainicjowało rozwój prawodawstwa dotyczącego całego cyklu życia statku: projektowania, budowy, eksploatacji i przygotowania do recyklingu. W artykule uwypuklono rolę konwencji HKC o bezpiecznym i przyjaznym dla środowiska recyklingu statków, ale jednocześnie zwrócono uwagę na powiązania między poszczególnymi etapami cyklu życia statku, w tym między fazą projektowania a fazą recyklingu, oraz na potrzebę stosowania strategii „Projektowania Zorientowanego na Recykling”.
Recycling of end-of-life ships, which is the last stage of their life cycle , may pose serious threats to the environment and workers’ health, due to the application of inappropriate technologies and procedures in scrap yards , especially those located in the Indian subcontinent , and also due to the presence of many hazardous substances in the ships construction and equipment. Paying attention of the world to the scale of the problem initiated the development of legislation for the entire life cycle of a ship: the design, construction, operation and preparation for recycling. The paper highlights the role of the Hong Kong Convention for the safe and environmentally sound recycling of ships, but also pays attention to the links between different stages of the life cycle of a ship, including those between the design phase and recycling phase. The neeed for the implementation of the “Design for Recycling” strategy is also highlighted.

It was a fateful expedition taking place between 1036 and 1041, and to this day it is a source of many controversies and speculations of researchers. The findings of the present paper suggest that the journey did not necessarily proceed to the lands of the Saracens or Byzantium but may have been part of the game played by Constantinople with its ally Tmutarkan, which opposed Jaroslav the Wise, these events unfolding in the north-eastern waters of the Black Sea.

In recent years, the authorities of Polish seaports have been conducted the active investment policy. The main stimulus to undertake these activities was the ability to gain financial support from European funds, mainly from the Cohesion Fund, the European Regional Development Fund and the Norwegian Financial Mechanism. In Poland, the port authorities were able to submit the investment projects to apply for EU support to the Infrastructure and Environment Operational Programme and the Regional Operational Programmes for the Pomeranian regions. The seaport authorities rebuilt quays, deepened and widened the waterways in the port basins, modernized communication accessibility to the ports from the land and the sea, as well as built logistics centers and introduced innovative solutions in the field of navigation and improved the safety of navigation. However, the analysis showed that investment activities in Polish seaports still allocate not enough space to issues of preparation of port infrastructure to support passengers' cruise ships and adaptation of the quays for terminals dedicated for handling of cruise ships. The objective of the study in this article is to assess the investment activities, realized by the Port of Gdynia Authority S.A, in the field of preparation of the port infrastructure in Gdynia to handle cruise ships.

Opis:
New chapter 4, added to Annex VI of MARPOL convention, put into effect regulations on the ships ‘energy efficiency. It makes mandatory since 1st January 2013 the so called Energy Efficiency Design Index (EEDI) for new ships and the Ship Energy Efficiency Management Plan (SEEMP) for new and existing vessels of 400 gt and above. There is a huge space to save the energy, improve the ships’ efficiency and reduce the GHG emissions for the sea going ships such as container carriers are. The aspects presented in the paper are based on the contemporary container vessels with the state of the art technology implemented to their design and operational stage. The estimation of the electric power and number of diesel generators with use of the statistical tools is the main aim of the paper. The container vessels fitted only with the diesel generators without any other type of electric generator unit are taken into account in the calculation process. The electric power equation has been determined, applying the multiple regression model with an absolute term, based on the ship’s parameters for the entire range of the container vessels’ load capacity TEU. It shown, the reefer containers RC and the main propulsion rating SMCR are the most important parameters statistically significant. It is calculated as well how the total ship’s electric power is very strictly dependent on the number of diesel generators installed on board. The reefer containers’ number and its assumed power considering the cargo type and the simultaneity coefficient are also presented in the article, as this impact the electric power demand. The different types of Power Management Systems for diesel generators load are discussed at the last stage of the paper.

ecological propulsion of seagoing ships
Opis:
Corrected VI Annex to MARPOL Convention requires from January 1st 2015 the use of low sulphur fuels on seagoing ships. The target of requirement is reduction of environment harmful substances in exhaust gases coming from marine fuels combustion. Areas of sea trade are divided into two zones: special Sulphur Oxide Emission Control Areas (SECA) for example Baltic Sea and areas outside SECA. On SECA sea areas the contents of sulphur in marine fuel should not excess 0.1% and on outside SECA the same is 3.5%. In the future i.e. from January 1st 2020, the maximum contents of sulphur in marine fuels on outside SECA areas should be 0.5%. These requirements create serious problems for ship owners operating worldwide. The first problem is considerable higher price of low sulphur fuels, which affects operational costs of fleet. The second problem is adaptation of ship engines to be fuelled with low sulphur fuels. At present, the heavy fuel oils being in common use on ships does not fulfil environ protection requirements. As a result, the use of new grades of marine fuels becomes necessity to fulfil environment protection requirements as well as price requirements to keep merchant fleet operation profitable. The wide use of “ecological fuel” i.e. natural gas as marine fuel is expected. The type of ship propulsion plant, which can be used in the future, will effect on the course of marine energetic plants development. The development of hybrid propulsion, electric propulsion, diesel engines fuelled with natural gas and turbine propulsion driven by natural gas. The paper includes proposal of combined turbine propulsion plant fuelled with natural gas, which according to authors can be leading type of marine propulsion plants in the future.

Opis:
Preliminary ship owners' assumptions for new ship consist of deadweight (for container vessel load capacity TEU), speed shipping line and others. Taking it as a base, in early stage of design one has to select propulsion type. This goal needs definition of principal dimensions of a vessel, which are the base for further calculations of hull’s resistance and evaluation of necessary power of main engine (engines) to fulfil shipping requirements. Selection of main dimensions of vessel is limited by rules regarding buoyancy, stability, hull strength, manoeuvring capability, and limitations related to seaways or harbours characteristic. In this paper is presented the methodology of calculation of principal parameters of a vessel, necessary for calculation of displacement in relation to vessel’s type, volumetric coefficients, Froude number, and others values affecting ship’s dimensions. It is about midship section coefficient, waterline coefficient, prismatic coefficients and hull feature and area coefficients. Those values are necessary for calculation of hull resistance. In the table are presented comparison of results of calculations above mentioned values and movement resistance and propulsion power of three container vessels representing different load capacity and one bulk carrier. There are also presented different calculation methods of transverse midship section coefficient and wet area coefficient, for 5000TEU container vessel.

Opis:
The paper analyses the performance of an Automatic Vessel Identification System on Medium Frequency (AVISOMEF), which works with the Grid Method (GM) on high density maritime European routes using real data and uniformly distributed data. Compared to other systems, AVISOMEF is a novelty, as it is not a satellite system, nor is it limited by a given coverage distance, in contrast to the Automatic Identification System (AIS), though in exceptional circumstances it leans towards it. To perform the analysis, special simulation software was developed. Moreover, a number of maritime routes along with their traffic density data were selected for the study. For each route, two simulations were performed, the first of which based on the uniform traffic distribution along the route, while the second one made use of real AIS data positioning of vessels sailing on the selected routes. The obtained results for both simulations made the basis for formulating conclusions regarding the capacity of selected routes to support AVISOMEF.

Opis:
During the currently ongoing development of methods for assessing the safety of ships, it is imperative that a compromise between the accuracy of the results and the accessibility of obtaining results is reached. This paper shows the calculations of a theoretical hull against damage stability regulations as included in SOLAS 2020, ICLL 66/88 as amended in 2003 and MARPOL 78. The rules included in the currently valid regulations require certain righting arm curve properties from vessels before and after potential damage, which does not pose a high difficulty level to engineers. However, for many engineers and scientists working with these rules, it is unclear what kind of behavior (particularly roll motion) these righting arm curve parameters correspond. In this paper, a correlation between the required GZ properties and the actual roll motion of a ship in waves, as calculated with the well-established method proposed by the ITTC, is revealed, and a comparison of the results to the currently in use regulations as well as comparison between the methods themselves is made. The comparison reveals the impact of GZ curve parameters on the roll motion of the ship.

Opis:
Gotowość bojowa okrętu jest w znacznym stopniu uzależniona od zdatności technicznej podstawowych urządzeń i mechanizmów okrętowych. Zdatność techniczna określona jest normami eksploatacyjnymi i uzależniona jest od stanu technicznego urządzeń. W trakcie użytkowania sprzętu wojskowego liczyć się należy z zużywaniem się urządzeń na skutek starzenia fizycznego, powstawania uszkodzeń eksploatacyjnych lub zniszczeń bojowych. Odtwarzanie zdatności technicznej okrętu realizowane jest po powrocie do portu, i podczas działań na morzu. W portach i bazach morskich zadania związane z odtwarzaniem zdatności technicznej realizowane są przez brzegowe elementy systemu remontowego. Podczas realizacji zadań na morzu załoga okrętu jest w stanie w ograniczonym zakresie, przy wykorzystaniu okrętowych zestawów remontowych, dokonać podstawowych obsług technicznych oraz napraw. Odtwarzanie sprawności i zdatności technicznej urządzeń okrętowych jest uzależnione od właściwego zabezpieczenia logistycznego tego procesu.
A ship’s combat readiness is significantly dependent on the technical worthiness of basic ship equipment and mechanisms. Technical worthiness is determined by operation rates and depends on the condition of equipment. While using military equipment, one may expect the wear and tear of systems resulting from physical ageing, operation or combat damage. The restoration of ship’s technical efficiency is completed after returning to the harbour or during operations at sea. The tasks of restoring technical efficiency are performed in harbours and in naval bases by ashore elements of the repair system. During operations at sea a crew is able, to a limited extent, to carry out basic technical maintenance. The restoration of the technical worthiness and efficiency of ship equipment depends on appropriate logistic support.

Opis:
A Yagi plasma antenna model was established by HFSS according to the relationship between plasma dielectric constant and electron density. The patterns were simulated by changing plasma parameters and the number of director dipoles. Results show that when the passive vibrators were switched off, the antenna is omnidirectional antenna. The directionality increases with the increase of the number of passive dipole and the main lobe of which narrows down. Then the plasma Yagi antenna model is established by plasma tube, the gain changed by changing the number of passive dipoles, so the plasma Yagi antenna has a very good reconfigurability. Results prove that the feasibility of the plasma Yagi antenna can be used on AIS base station of Ships’ Routeing waters. It can promote the communication and capability of maritime supervision in Ships’ Routeing waters.

Opis:
Ships' stability criterion due to turning is not up-to-date and requires amendments. Redesigning the criterion should be based on scientific research, but there is a lack of accurate procedures and formulas enabling the calculation of the heeling moment caused by centrifugal forces as a function of time. Measurements of a ships’ heel caused by turning on a model-scale or full-scale may provide a basis for such an analysis. This paper creates such a procedure, including appropriate formulas, leading to the extraction of the heeling moment caused by centrifugal force from other heeling moments acting on a ship during turning. One model-scale experiment is described in detail, and the results of the calculations are presented. The paper concludes that it is possible to extract this moment as a function of time and presents an example of such a calculation.
