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.
