Opis:
The biggest problem in the process of implementation of the new sea areas project or aids to navigation systems is to check the assumptions without compromising security on real waters. Today, digital models are available for easy and inexpensive replacement of the research methods used so far. For this purpose the navigational and maneuvering simulators are perfect. Simulators as a research tools allow you to define a more realistic and accurate data for the study and evaluation sea areas. The purpose of the simulation is to identify and reduce the risk for seafarers during navigation on the waterways, canals and port areas. These include quantitative and qualitative assessment of the canals and fairways construction. The main requirement for a simulation system is to have a multi-task simulation software, which includes effective tools for repositioning and designing safe waterways and port infrastructure. The Institute of Navigation and Maritime Hydrography of the Polish Naval Academy since the eighties of the twentieth century is carried out projects in the field of navigational and hydrographic support of human activities at sea. This is possible thanks to the extensive set of simulation tools. Planning this tasks in a simulators software environment allow not only to design of virtual counterparts of real sea areas, but also to evaluate the quality of manufactured parts before their actual exposure to sea areas.
Największym problemem w procesie realizacji projektu budowy nowych akwenów morskich lub elementów systemów oznakowania nawigacyjnego jest sprawdzenie poprawności przyjętych założeń bez obniżania poziomu bezpieczeństwa na realnych akwenach. Współcześnie dostępne są cyfrowe modele pozwalające na łatwe i tanie zastępowanie dotychczas stosowanych metod badawczych. W tym zakresie idealnie sprawdzają się symulatory nawigacyjno-manewrowe. Symulatory jako narzędzia badawcze pozwalają określać bardziej realistyczne i dokładne dane do badania i oceny dróg oraz akwenów wodnych. Celem symulacji jest identyfikacja i zmniejszenie ryzyka działalności marynarzy w specyficznych warunkach dróg wodnych, kanałów i akwenów portowych. Obejmuje ona ocenę ilościową i jakościową ukształtowania kanałów i torów wodnych. Głównym wymaganiem w odniesieniu do systemu symulacji jest posiadanie wielopoziomowego oprogramowania symulacyjnego, które obejmuje efektywne narzędzia repozycjonowania i projektowania bezpiecznych dróg wodnych i elementów infrastruktury portowej. W Instytucie Nawigacji i Hydrografii Morskiej Akademii Marynarki Wojennej od lat osiemdziesiątych XX wieku realizuje się projekty z zakresu nawigacyjno-hydrograficznego zabezpieczenia działalności ludzkiej na morzu (NHZ). Jest to możliwe dzięki posiadaniu bogatego zestawu narzędzi symulacyjnych. Planowanie NHZ w wirtualnym środowisku symulatorów pozwoliło nie tylko na zaprojektowanie wirtualnych odpowiedników realnych fragmentów polskich obszarów morskich, ale również na ocenę jakości wytworzonych elementów NHZ przed ich rzeczywistym wystawieniem na akwenach morskich. W artykule zaprezentowano możliwości symulatorów na przykładzie planowanego kanału żeglownego przez Mierzeję Wiślaną. Przedstawiono algorytm postępowania podczas tworzenia akwenu i próby manewrowe dla maksymalnej jednostki przewidzianej dla nowo powstałego akwenu.

Opis:
Use of the ship maneuvering simulator (SMS) is at the core of pilot trainees education and training, so it is desirable to have an evaluation method that can be completed shortly after each berthing training session. There are basically two methods of docking maneuvering that pilot trainees learn: one in which the ship enters from outside the port and is berthed directly at the target quay, and a second method in which the vessel carries out a turn in front of the target quay before berthing. The authors suggested an evaluation index in a previous study concerning the first docking method. In the present study, the authors propose an evaluation method for the case of berthing the vessel using the turning maneuver. Since the index obtained by this method offers a single numerical benchmark, it is an easy–to‐understand result of the training exercise. The authors carried out experiments using a SMS and confirmed that the proposed evaluation method is effective and helpful to improve the effectiveness of SMS training.

The paper presents the stages of creation of an autonomous historical navigational system simulator working both in real and accelerated time. The simulator allows performance of navigation tasks from the time of the ancient Vikings, as well as to fix a position by using the Decca system on a real Mk21 receiver recreated to cooperate with the artificial Decca system model. The Viking solar compass discovered on Wolin Island in 2013 was the trigger for creating such a simulator as part of a broader exhibition of navigational systems and tools. The main intention of the exhibition is to demonstrate the hyperbolic navigation application that links both systems.

Opis:
A fast time simulation tool box is under development to simulate the ships motion with complex dynamic models and to display the ships track immediately for the intended or actual rudder or engine manoeuvre. Based on this approach the innovative “Simulation Augmented Manoeuvring Design and Monitoring” - SAMMON tool box will allow for (a) a new type of design of a manoeuvring plan as enhancement exceeding the common pure way point planning (b) an unmatched monitoring of ship handling processes to follow the underlying manoeuvring plan. During the manoeuvring process the planned manoeuvres can be constantly displayed together with the actual ship motion and the predicted future track which is based on actual input data from the ship’s sensors and manoeuvring handle positions. This SAMMON tool box is intended be used on board of real ships but it is in parallel an effective tool for training in ship handling simulators: (a) in the briefing for preparing a manoeuvring plan for the whole exercise in some minutes, (b) during the exercise run to see the consequences of the use of manoeuvring equipment even before the ship has changed her motion and (c) in debriefing sessions to discuss potential alternatives of the students decisions by simulating fast variations of their choices during the exercises. Examples will be given for results from test trials on board and in the full mission ship handling simulator of the Maritime Simulation Centre Warnemuende.

“Safe voyage from berth to berth”: This is the goal of all e-Navigation strains driven by new technologies, new infrastructures, and new organizational structures on bridge, on shore, as well as in the cloud. To facilitate these efforts suitable engineering and safety/risk assessment methods are required. Understanding maritime transportation as a sociotechnical system allows the usage of system-engineering methods. Simulation-based test beds for verification and validation (V +V) of e-Navigation technologies are important methods to obtain functional safety and reliability. The modeling and simulation toolset HAGGIS is a cosimulation system for the evaluation of e-Navigation concepts and systems. It provides a maritime traffic simulator and a physical world (n-body) simulator and services for finding rare events of failures. HAGGIS is accompanied by the physical test bed LABSKAUS, which implements a reference port and waterways. This paper describes an integrated and seamless approach for developing new e-Navigation technologies starting with virtual simulation-based safety assessment and ending in physical real-world demonstrations. It gives an overview of the actual test bed and introduces requirements, concepts and elements of HAGGIS and LABSKAUS, which are joined in the e-Maritime Integrated Reference Platform (eMIR) test bed.

The paper argues for the necessity to combine MMR methods (questionnaire, interview), gaze tracking as neuroscience tool and sentiment/opinion techniques for personal satisfaction analysis at the maritime and training education (MET) and proposes a practical research approach for this purpose. The purpose of this paper is to compare the results from gaze tracker (Face analysis tool) of three experiments & sentiment analysis of two experiments for satisfaction evaluation of the students-users’ (subjective) satisfaction of the maritime education via user interface evaluation of several types of educational software (i.e. engine simulator, ECDIS, MATLAB). The experimental procedure presented here is a primary effort to research the emotion analysis (satisfaction) of the users-students in MET. The gaze tracking & sentiment analysis methodology appears to be one sufficient as evaluation tool. Finally, the ultimate goal of this research is to find and test the critical factors that influence the educational practice and user’s satisfaction of MET modern educational tools (simulators, ECDIS etc.).

Opis:
Safety of navigation is especially challenging and critical when a ship approaches and manoeuvres in harbour areas. Improving the safety especially in the first and last phase of a voyage is crucial and requires measures addressing both the human and technical-technological elements including support systems that shall provide human operators with information relevant for decision making. The present situation is characterized by the introduction of numerous sophisticated technical and support systems often integrated with several components becoming increasingly complex. On the users end, changes are not that obvious and not that rapid as for technology. However, new approaches are under development or already in use. They are characterized by applying and adapting solutions from other transport modes. In this way, tasks and procedures on ships, that are highly safety-relevant and containing high portions of manoeuvring activities have been changed to high back-up procedures as in air planes. For port manoeuvres e.g. the system of pilot/co-pilot was introduced on ferries in a sense that one officer is operating and the other is monitoring and checking the safe performance. In cruise shipping, new structures replacing the traditional rank-based with a flexible system based on job functions. This system creates a kind of a safety net around the person conning the vessel. Each operation is cross checked before execution by one or two other persons. The first obvious consequence is higher costs due to doubling personnel. On the other hand there is also a need for a technology appropriately supporting the checking officer by enabling her or him to monitor what the conning officer is doing. “Fast-Time Manoeuvring Simulation Technology” (FTS) developed at the Institute for Innovative Ship Simulation and Maritime Systems (ISSIMS) has huge potential to fulfil this task. FTS calculates within one second of computing time up to 1000 seconds of real manoeuvring time by a very complex ship-dynamic simulation model for rudder, engine and thruster manoeuvres. It enables prompt prediction of all manoeuvres carried out by the conning officer for the observing officer, too. Predictions of path and motion status allow all officers to see whether the manoeuvring actions have at least the correct tendency or indicating the need for corrections. This new type of support is called Simulation-Augmented Manoeuvring Design and Monitoring (SAMMON) – it allows not only overlooking the next manoeuvring segment ahead but also for the following or even for series of manoeuvring segments. This technology has been used within two research projects: COSINUS (Co-operative Ship Operation in Integrated Maritime Traffic Systems) set out for implementing FTS into integrated ship bridges and to also communicate the manoeuvre plans and display it to VTS centres. Within the European project MUNIN (Maritime Unmanned Navigation through Intelligence in Networks) this technology has been used to investigate if it is possible to steer autonomous ships, in case it would be necessary.

„Bezpieczna podróż od nabrzeża do nabrzeża” — to cel całego procesu e-nawigacji, napędzanego nowymi technologiami, nową infrastrukturą i nową organizacją pracy na mostku, na lądzie, ale także w technologii chmury znanej z informatyki. By ułatwić te wysiłki, należy zastosować również odpowiednie metody ocena ryzyka. Rozumiejąc transport morski jako system socjotechniczny, można do tych celów zastosować metody inżynierii systemów. Formalna ocena ryzyka, a także oparta na symulacjach weryfikacja i walidacja technologii e-nawigacji to ważne metody oceny bezpieczeństwa i niezawodności systemu. Modelowanie i zestaw narzędzi symulacyjnych HAGGIS okazują się odpowiednimi instrumentami do opisu systemu i formalnej analizy ryzyka. Wyznaczają ramy dla modelowania procesu, sporządzenia drzewa błędów i generowania wykazu zagrożeń, jak również otoczenia fizycznego i symulacji ruchu morskiego. HAGGIS jest wspierany przez rzeczywisty poligon testowy LABSKAUS, który implementuje port i drogi wodne. Dodatkowo obejmuje on eksperymentalny system nadzoru ruchu (VTS) oraz mobilny zintegrowany mostek umożliwiający realne eksperymenty dla oceny technologii, testowania i demonstracji. W artykule opisano zintegrowane, spójne podejście do rozwijania nowych technologii e-nawigacji, zaczynając od wirtualnej symulacji, a kończąc na demonstracjach w fizycznej rzeczywistości.

Maritime Safety and Security on board ships very much depends on well trained crews. That is why training and exercising emergency response procedures as well as efficiency in reliable management are extremely necessary. On the other hand research as well as technological development in safety and security, tools and other kinds of technical and organizational systems contribute to further improvement and guarantee high levels of safety and security in maritime transportation. Simulation facilities are essential for both exercising and training but also for research and technological development. This paper introduces the innovative concept of a safety and security training simulator (SST7) and describes research work related to the implementation of training scenarios. Selected results of a case study will be presented. A shorter version of this paper was originally presented at the International Conference on “Marine Navigation and Safety of Sea Transportation” at Gdynia in June 2013.

The paper presents a mathematical model of a positional game of the safe control of a vessel in collision situations at sea, containing a description of control, state variables and state constraints as well as sets of acceptable ship strategies, as a multi-criteria optimisation task. The three possible tasks of multi-criteria optimisation were formulated in the form of non-cooperative and cooperative multi-stage positional games as well as optimal non-game controls. The multicriteria control algorithms corresponding to these tasks were subjected to computer simulation in Matlab/Simulink software based on the example of the real navigational situation of the passing of one’s own vessel with eighteen objects encountered in the North Sea.

Opis:
Ship collision is a hazardous event within the chain of maritime transport. Collisions may result in human losses, adverse economic consequences, and environmental damages causing significant impact to local societies and related activities. A major factor in any risk analysis concerning ship collisions is the probability of these collisions occurring. The purpose of this study is to assess the probability of ship-to-ship collision in the Aegean Sea. The basic concept of the developed model is to (statistically) simulate traffic flow in the area of interest and determine the collision candidates; this will be implemented in a pilot study in a segment of the Aegean Sea. The input of this effort is based on values that are extracted from statistical analysis of the international fleet in combination with the study of maps depicting traffic flow in the studied area. Hence, it does not employ detailed AIS data. The obtained results are presented and their agreement with actual incidents is discussed in depth. The paper concludes with interesting insights of the aforementioned tasks.

Opis:
One of the primary factors that affect the safe maritime navigation is the insufficient experience and skill of an apprentice officer, which may be improved using simulation-based training by ensuring operational efficiency. This study aims to determine appropriate factors for achieving effective and intensive simulation-based training of apprentice officers and present the guidelines for such a training scheme. Initially, a marine traffic risk model, which interprets and accurately measures the risk of collision with other vessels, is analyzed to derive the most influential factors in safe navigation. Subsequently, simulation experiments are conducted by applying machine learning to verify the required safe navigation factors for effectively training the apprentice officers. As a result of the above analysis, it was confirmed that the factor affecting safe maritime navigation was the distance from other vessels. Finally, the differences between these distances in the simulations are analyzed for both the apprentice officers and the experienced officers, and the guidelines corresponding to both these cases are presented. This study has the limitation because of the difference between the ship maneuver simulation and the actual ship navigation. This can be resolved based on the results of this study, in combination with the actual navigation data.

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

Opis:
Maritime shipping is a set of complex activities with a large number of actors involved. We focus on a subset of illegal maritime activities, such as armed robberies, maritime piracy or contraband smuggling. To fight against them and minimize their negative impact naval authorities typically introduce a number of countermeasures, such as deployed patrols or surveillance agents. Due to very high costs of countermeasures it is often beneficial to evaluate their impact using a simulation, allowing what-if analysis and evaluation of a range of scenarios before actually deploying the countermeasures. We introduce BANDIT, an agent-based computational platform, which is designed to evaluate scenarios with an accent on the modeling of different types of illegal behavior and on the interaction between agents. The platform consists of an agent behavior modeling system and a multi-agent maritime simulator. The platform allows the definition of a number of scenarios through a simple configuration and it offers the means to run these scenarios in a single or a batch mode and evaluate the results as single or aggregate data sets respectively. We demonstrate the usefulness of the platform on the scenarios of the drug smuggling problem in the seas surrounding Central America. Senario outcomes (e.g., heatmaps of activities, set of trajectories etc.) are subsequently used to help with the design of effective countermeasures, i.e., allocating naval patrols and planning their patrol routes.

Opis:
For logistic chains that have a maritime component, the ports transition involves a set of specific operations inside maritime container terminals. This can be cargo handling operations from the terrestrial vehicle in the storage area of ports, from port storage area in the maritime ships, as well as storage operations in the port area and other container terminal activities. Taking into consideration the multi-flow interactions and the non-uniform arrival of vessels and in-land vehicles, discrete event simulation stands as a feasible technique for investigating berthing capacity during the initial planning stage of the terminal or for operative planning of logistic processes at the terminal. If the storage area is analysed as a queuing system, the quality serving attributes could be evaluate. When different distributions for arrival flows of the containers in the maritime container terminal are taken into consideration, the quality serving attributes are difficult to estimate. In our paper, a discrete simulation model is developed in ARENA software for case of a maritime container terminal. The estimation of the general measures of performance for the container port terminals through simulation could provide data for the implementation in the management plans by port administrations.

Opis:
This article describes a proposed productivity simulation model enabling container terminal operators to find optimization possibilities. A research of more than forty terminals has been done, in order to provide a helping tool for maritime container terminals. By applying an adequate simulation model, it is possible to measure and increase the productivity in all subsystem of the maritime container terminal. Management of a maritime container terminal includes a vast number of different financial and operational decisions. Financial decisions are often in a direct connection with investments in infrastructure and handling equipment. Such investments are very expensive. Therefore, they must give back the invested money as soon as possible. On the other hand, some terminals are limited by the physical extension and are forced to increase annual throughput only with sophisticated equipment on the berth side and on the yard as well. Considering all these important facts in container and shipping industry, the proposed simulation model gives a helping tool for checking the productivity and its time variation and monitoring competitiveness of a certain maritime terminal with terminals from the same group.
W artykule przedstawiono propozycję modelu symulacyjnego umożliwiającego operatorom terminali kontenerowych optymalizację swoich działań. Badania modelowe obejmowały ponad 40 terminali morskich w celu wyznaczenia odpowiednich narzędzi wspomagających zarządzanie nimi. Wykorzystanie odpowiedniego modelu symulacyjnego pozwala mierzyć i zwiększać produktywność we wszystkich podsystemach morskiego terminalu kontenerowego. Zarządzanie takim terminalem opiera się o szereg różnych wskaźników finansowych i decyzji. Decyzje finansowe są często ścisle powiązane z inwestycjami w infrastrukturę i sprzęt transportowy. Niektóre inwestycje są bardzo kosztowne, w związku z tym muszą się zwrócić możliwie najszybciej. Z drugiej strony istnieją ograniczone możliwości rozwoju obszarowego i terminale są zmuszone do zwiększenia rocznego wykorzystania kei i innych stanowisk. Rozważając wszystkie te istotne fakty dotyczące transportu morskiego i intermodalnego z wykorzystaniem kontenerów, proponowane eksperymenty symulacyjne pomagają w monitorowaniu produktywności, jej zmienności w czasie i konkurencyjności określonego terminala kontenerowego wśród terminali z tej samej grupy.

Opis:
Development of the specialists’ professional competence can be achieved both directly during games and a post-game analysis. Since the continuing education system must respond quickly to changes in external and internal conditions it is necessary to adapt it to new conditions. This is possible when scientific and pedagogical staff of the university is ready to the project activity. In this regard the problem of teachers training for such activities is actual one. The most effective methods of such preparedness development are game methods and, in particular, business and simulation games. There are situations of "conflict" of interest during games as in real life and teachers of different subjects must search a compromise that satisfies basic learning goals. During the game, participants consider many variants for solving certain project tasks, methods of training schemes designing. It is very important in the sphere of maritime specialists training. Participants are often faced with a lack of methodological training that is an important motivating factor for self-development and new knowledge. Business and simulations games have an aim to develop readiness of teachers to design educational systems. The paper discusses the methodological approaches to the development of conceptual designs of professional business/simulation games for seafarers and managers of maritime transport and describes a business/simulation game scenario “Ensuring the safety of maritime cargo transportation”. The problems of the game organization, a results analysis and developing measures to improve the system of training and self-improvement plans of participants are considered.

Opis:
This paper evaluates near ship-ship collision situations in the Tagus River Estuary using a simulation model of ship navigation in restricted waters. The simulation model consists of a ship collision avoidance model based on the Artificial Potential Field (APF) method, which has been improved to account for the lateral distribution of traffic along the route, the ship type and length and speed development of the ships along the trajectory. AIS data of ships entering and leaving the port of Lisbon are analysed to obtain the main characteristics of traffic parameters used as input for the traffic simulation model, such as: the routes of the vessels, speed distribution along the routes, traffic density and characteristics of the ships in each route, among others. First, the improved model of ship navigation and the Monte Carlo simulation technique are used to simulate the marine traffic in the Tagus River Estuary. Then, the concept of “ship domain” is used as collision criterion to determine the number of near collisions and the locations where they are most likely to occur. Finally, the simulation results are compared to the ones obtained from raw AIS data to assess the capability of the simulation model for marine traffic risk analysis.

Opis:
Maritime education and training (MET) has a long tradition of using simulator training to develop competent seafarers and relevant seafaring skills. In a safety critical domain like maritime industry, simulators provide opportunities to acquire technical, procedural and operational skills without the risks and expense associated with on-the-job training. In such training, computer-generated simulations and simulators with higher realism are inferred to better training outcomes. This realism, or the extent to which simulators replicate the experience of a real work environment, is referred to as the “fidelity” of a simulator. As the simulation technology develops, the maritime industry adapts to more advanced, higher fidelity simulators. However, the cost of a simulator generally increases with increasing fidelity, and thus practical and economic constraints must be considered. In this paper, we investigated two types of simulators on perceived skill development of the students at engine room simulation training. We compared the self-efficacy levels of 11 second year marine engineering students and their perceived skill development between two different fidelity engine room simulators. The result suggests that students have higher motivation and prefer to train with immersive training simulators compared to the traditional training. This article aims to add to existing knowledge on the influence of fidelity of simulators in training effectiveness in maritime education and training.

Opis:
In this manuscript, development and preliminary results of a simulation based risk modeling study for the Strait of Istanbul is presented. The goal of this research is to analyze the risks involved in the transit vessel traffic in the Strait of Istanbul. In the first step of the study, the transit vessel traffic system in the Strait of Istanbul has been investigated and a simulation model has been developed. The model gives due consideration to current traffic rules and regulations, transit vessel profiles and schedules, pilotage and tugboat services, local traffic, meteorological and geographical conditions. Regarding risk assessment, two sets of factors are used to evaluate the risk of accident in the Strait: the proba-bility of an accident and its potential consequences, as estimated and evaluated at various points along the Strait. Experience has shown that maritime accident occurrences can be very dissimilar from one another and therefore, probabilistic analysis of accidents should not be done independent of the factors affecting them. Thus, in this study, we have focused on the conditional probability of an accident, under a given setting of various accident causing factors. Unfortunately, historical accident data is by far insufficient for a proper sta-tistical consideration of all possible settings of these factors. Therefore, subject-expert opinion is relied upon in estimating these conditional accident probabilities. Assessment of the consequences of a given accident (in terms of its effects on human life, traffic efficiency, property and environment) was also accomplished using a similar approach. Finally, by integrating these assessments into the developed simulation model, the risks observed by each vessel at each risk slice are calculated in regard to the natural and man-made conditions surrounding. A sce-nario analysis is performed to evaluate the characteristics of the accident risk as the vessel moves along the Strait. This analysis allows us to investigate how various factors impact risk. These factors include vessel ar-rival rates, scheduling policies, pilotage service, overtaking and pursuit rules, and local traffic density. Policy indications are made based on the results of these scenarios.

Simulator based training has its own unique features and problems associated with it. There is a need to discuss these issues in order to understand the real meaning of simulator based training and to handle it effectively. Like other fields of training, use of simulation in the maritime industry is owing to the multiple factors covering technological, financial and training needs of the time. When properly used, supported by well trained and experienced instructors, simulator training, through its risk free environment, can contribute to a reduction in accidents and improve capability and efficiency, by providing trainees with the necessary experience and self confidence to carry out their roles, functions and tasks.

Opis:
The e-Navigation initiative of IMO and IALA has stimulated and inspired a number of ambitious research projects and technological developments in the maritime field. The global transportation of goods is not only facing rapidly growing ship dimensions but also increasing industrial off shore activities, changing the relation between the need of areas for safe and reliable vessel traffic and its availability. Off shore activities is increasingly limiting the available navigable spaces and concentrating traffic flows, especially in coastal waters and port approaches. Enhanced technical systems and equipment with numerous added functionalities are in use and under further development providing new opportunities for traffic surveillance and interaction. Integrated Bridge and Navigation Systems on board modern ships not only support the bridge teams and pilots on board, but also allow for more comprehensive shore-based traffic monitoring and even allow for re-thinking of existing regimes and procedures on traffic management. A sophisticated manoeuvring support tool using fast real-time simulation technology and its application for on board support as well as for its potential integration into enhanced shore-based monitoring processes when linked with the ‘Maritime Cloud’ will be introduced. The potential for contribution to generate harmonized collision warnings will be discussed and explained. This paper is a reviewed and extended version of (Baldauf, Benedict & Gluch, 2014).

Opis:
The primary purpose of a marine casualty investigation is to seek to establish the causal factors of the casualty with a view to learning the hard lessons and avoiding a repetition. The broad questions of an investigation: ""who?, what?, when?, where?, why?, and how?"", all help to uncover the facts. The investigation sequence will cover a diverse range of fact-finding activities, amongst which, as often the case, may be a requirement for “conducting specialised studies”. Following the fact-finding stage the typical investigation progresses to analysis of the facts, reaches conclusions and makes recommendations. Keeping an open mind, to avoid premature conclusions, requires the separation of the fact-finding and analysis phases. But the analysis may well help to identify missing pieces of evidence, or different lines of enquiry that may otherwise have gone undetected. As an effective reconstruction tool, a full-mission bridge simulator offers an opportunity to examine a broad spectrum of environmental conditions and vessel characteristics, as well as equipment failures, human factors and operating procedures. A casualty incident can be reconstructed in a real-time simulated environment, to aid more detailed analysis. Within the usual confines of the legal process, comprehension of nautical ‘black magic’ is greatly simplified for non-mariners, by seeing the simulated casualty incident unfold, in real-time or in selected short-time segments.

Opis:
Despite the efforts of all stakeholders maritime accidents still occur, most commonly caused by human failure. Efficient team work is a vital tool in preventing occurrence or rectifying the errors and violations. Therefore Bridge Resource Management course focuses on developing and sustaining work teams. Unfortunately, team work can be hampered by many factors, including poor organisation, cultural differences, improper attitudes and behaviours, as shown by analysis of many accidents and it is important to address these issues during trainings. As a starting point for a discussion simulation training can be used. In this paper we propose three scenarios based on real accidents, which address problems that are usually not familiar to students: authority gradient, desire for harmony in a group and antagonism between specialties.
