From time immemorial, the main type of human activity at sea was transport of goods, then fishery, exploration of overseas territories, combating enemy’s vessels etc. The twentieth century visualized clearly also a military activity, whereas the latter part of the century also an industrial one on the continental shelves. Progress in these fields was the leading motive power considerably increasing human activity at sea beyond transport. The paper shows results of research work on designing of human activity at sea in the navigational simulators environment. These research works have been conducted in Institute of Navigation and Hydrography Polish Naval Academy.
Wszechstronny i dokładny trening na lądzie, pozwala zmniejszyć liczbę wypadków na morzu. Dzięki symulatorom nawigacyjnym, można szkolić załogi statków, nie narażając ich na niebezpieczeństwo. Szczególnie ważny jest trening w obsłudze radaru nawigacyjnego. Podczas pracy zostały porównane zobrazowania radarowe symulatorów nawigacyjnych w polskich uczelniach morskich oraz wybrano obraz najlepiej oddający rzeczywistość. Ponadto przedstawiono ogólny opis wykorzystanych do badań symulatorów nawigacyjnych.
A versatile and accurate training on the land, lets reduce the number of accidents at sea. Thanks to navigational simulators, it is possible to train crews of ships, not exposing them to a danger. A training in the operation of the radar is particularly important. Comparison of radar depicting in Polish Maritime colleges have been analyzed during my work and the best image conveying reality has been chosen. Moreover a general description from the radiolocation as well as navigational simulators has been presented.
Content available remote Research on Ship Navigation in Numerical Simulation of Weather and Ocean in a Bay
For safe navigation, high-resolution information on tidal current, wind and waves is very im-portant. In coastal areas in particular, the weather and ocean situation change dramatically in time and place according to the effects of geography and water depth. In this paper, high-resolution wave data was generated using SWAN as a numerical wave model. To estimate waves, wind data is necessary. By using the mesoscale meteorological model of WRF-ARW, detailed wind data was generated. The tidal current data was generated by using POM. We simulated tidal currents, wind and ocean waves for the duration of a typhoon passing over Japan in Sep-tember of 2004. Secondly, we simulated ship maneuvering using simulated tidal current, wind and wave data. For the ship maneuvering model, the MMG (Mathematic Modeling Group) was used. Combining high-resolution tidal current, wind and wave data with the numerical navigation model, we studied the effects of tidal current, wind and waves on a ship’s maneuvering. Comparing the simulated route lines of a ship with the set course, it was recognized that the effects of the tidal current, wind and waves on a moving ship were significant.
Content available remote A Simulation Model for Detecting Vessel Conflicts Within a Seaport
Conflicts represent near misses between two moving vessels, and often occur in port waters due to limited sea space, high traffic movements, and complicated traffic regulations. Conflicts frequently result in congestion and safety concerns. If conflict risk can be predicted, one could take appropriate measures to re-solve conflicts so as to avoid incidents/accidents and reduce potential delays. To the best of this researcher’s knowledge, no systematic study has been carried out on the issue of detecting marine traffic conflicts. In this paper, we present an algorithm designed to determine a conflict using the criterion of vessel domain. The al-gorithm aims to evaluate the relative positions of vessel domains to detect potential conflicts. To implement the algorithm, a simulation model has been developed in Visual C++. The model at present provides a single function for conflict detection but can be expanded to a multi-functional system for resolving conflicts in fu-ture work.
Content available remote A Methodological Framework for Evaluating Maritime Simulation
The application of simulation courses according to STCW conversion is addressed to the edu-cation of marine deck and engine officers in order to familiarize with the working environment, emergency contingency training and trouble shooting. This paper presents a framework which evaluates the participants in the courses of simulator, according to their concerns and their level of use. Actually this framework is an innovative concept which tries to identify how the contributors think and work in this virtual environment. The results from the application of this framework are presented in this paper, based on student’s concerns, reactions and level of use with respect to the exercise and efficiency of simulation training courses taken place at the Merchant Marine Academy of Engine Officers on Chios Island. The main goal of our research is to promote a general framework which can be easily applied in any marine simulation curses and will be very useful to the instructor for reorganizing, redesigning and finally configurating the Simulation Courses accord-ing to their participant.
Content available remote Simulating Method of Ship’s Turning-basins Designing
The paper presents one of the methods of ship’s turning-basins designing. The simulating method is more and more often used to the defining parameters projected turning-basins, testing of existing turning-basins and the improving of the manoeuvring practice on the particular manoeuvring basin.
Safe operation of ships in restricted areas, in particular in canals and waterways of restricted width and depth, often with presence of current. depends on operator skill. One way to influence operator skill and hence to increase safety against collisions and groundings is proper training of operators in realistic envi-ronment. Training could be accomplished on board ships, which takes, however, long time but also on simula-tors. There are two types of simulators: full mission bridge simulators (FMBS) working in real time and phys-ical simulators using large manned models in purposeful prepared training areas (MMS). Capabilities of both type simulators are discussed in detail. Capability of FMBS depends on computer codes governing them. Few examples of capability of FMBS to reproduce correctly ship handling situations are shown. There are few MMS in the world, one of which is Ilawa Ship Handling Research and Training Centre. In the centre models of several types of ships are available and training areas are developed representing different naviga-tional situations. The main purpose of the training exercises is to show the trainees how to handle the ship in many close proximity situations, in the presence of current, in very restricted water areas etc.
