    Opis:
    The paper contains a description of different possibilities of stopping a large ship equipped with azipods. The model tests were carried out to compare the effectiveness of stopping the ship using the different methods. The ship model used in stopping tests reproduces a large LNG carrier of capacity ~150 000 m3.

    Opis:
    There have been developed numerous mathematical models describing the motion of a ship. In opinion of present authors the CFD is mature enough to determine with confidence the hydrodynamic characteristics necessary to simulate ship manoeuvres. In this paper the authors present the attempt to determine the hull hydrodynamic forces using the results of CFD computations of ship flow. Results show qualitative agreement with reference data and reveal shortcomings due to simplifying assumptions applied in CFD computations.

    Opis:
    In this paper approach parameters widely used collision avoidance systems such as the distance at closest point of approach and time to the closest point of approach and less known and used as the distance on course, the distance abeam and any distance and the times intervals to their occurrences are derived, analyzed and graphically interpreted in the combined coordinate system for position and motion. They can be used in collision avoidance systems and for reversed purposes - manoeuvring to required approach parameters, intentional approaches and naval tactical manoeuvres.

    Opis:
    CRG casualties create one of the major type casualties in shipping. Prevention of CRG casualties is an important issue, especially because of the number of CRG casualties has increased almost twice during recent years. For the great majority of all CRG casualties human factor responsible, and the increasing number of these casualties might be attributed to poorer qualifications of ship masters who have not enough experience in handling very large ships put into operation presently. Risk analysis is a modern method for assessment of safety level of technical systems. This tool may be the used to investigate causes of casualties and to find out most effective prevention measures. Risk analysis is widely used in many areas; in case of marine technology it is used routinely in off-shore technology. The author investigates possibilities to apply risk analysis in the area of ship handling with the focus on human factor. This is preliminary study where possible methodology for hazards identification and risk assessment in respect of CRG casualties are investigated and risk control options are suggested. Various aspects of the influence of human factor in collision avoidance are listed and in particular the effect of training is stressed.

    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.
