    Opis:
    The process of the ships docking, especially very large ships, is an very risky operation in confined and busy port waters. The similar difficult is the task to pass along any channel, river, strait or similar water road. The basic difficulty causes maneuvering with the great mass of the ship in situation of small space to maneuvers, the large inertia of the object and poor maneuvering properties at small speeds occurring in such circumstances. An additional factor, which make this task more difficult is the influence of the wind and the sea current on the hull of the inert ship as well as consequences of the limited visibility. The bad weather can cause the necessity to delay the maneuver. However this joins with heavy costs. An alternative is usage of systems supporting this process. In this paper nowadays accessible systems for augmentation the docking and harbor navigation are analysed. There are: shore based (active or passive) and ship based (active). This paper is prepared in the frame of Bonus project call 2012 ‘The Captain Assistant system for Navigation and Routing during Operations in Harbor’.
    Proces wprowadzania statków do portów, zwłaszcza statków bardzo dużych, to ryzykowna operacja, szczególnie na wodach ograniczonych i zatłoczonych. Podobnie trudne jest zadanie przeprowadzenia statku przez jakikolwiek kanał, rzekę, cieśninę lub podobną drogę wodną. Podstawowa trudność wynika z wielkiej masy statku w sytuacji małej przestrzeni, wielkiej bezwładności obiektu i złych własności manewrowych przy małych szybkościach, typowych dla takich okoliczności. Dodatkowym czynnikiem utrudniającym to zadanie jest wpływ wiatru i prądu morskiego na kadłub bezwładnego statku, jak również konsekwencje ograniczonej widoczności. Zła pogoda może spowodować potrzebę odłożenia manewru na później, jednak łączy się to z dużymi kosztami. Alternatywą może być zastosowanie systemów wspierających ten proces. W artykule przedstawiono analizę dostępnych obecnie systemów dedykowanych dla wspierania takich operacji w portach oraz żeglugi w akwenach ograniczonych. Systemy te występują w wariantach brzegowych (aktywne lub pasywne) oraz okrętowych (aktywne). Artykuł został przygotowany w ramach projektu BONUS 2012 „System wspomagania kapitana w procesie nawigacji w trakcie operacji portowych”.

    Opis:
    Growth of demand for containerized cargo shipping has put more ports into pressure to accommodate larger vessels. Considering the limitations on dimensions of navigation channels, this is not feasible unless aiming for significant capital dredging or alternatively creating high precision predictions of vessel motions subjected to environmental forcing and interaction with shallow and restricted waterway. NCOS ONLINE (Nonlinear Channel Optimisation Simulator) is a state of the art navigation support tool which combines DHI’s high level forecast of environmental conditions with mathematical model of ship motions to add an extra level of accuracy in predicting the under-keel clearance and vessel swept path to boost the efficiency of navigation and pilotage within restricted channels. NCOS Manoeuvring Module utilizes an autopilot scheme based on PID (Proportional / Integral / Derivative) controller and Line of Sight Algorithm to FORCE Technology’s SimFlex4 manoeuvring solver for prediction of manoeuvring ship swept path and response, which will effectively bring the accuracy of real time full bridge simulator to fast time operation support tool. In this paper, the result of mathematical model is validated against fullscale measurements of containership transits through Port of Auckland Navigation channel by comparing pilot commands, leeway drift and swept path through output of portable pilotage unit. According to the results the model is found promising to predict the behaviour of human pilots with precision required in operational use. Finally, the swept path and manoeuvring performance of a sample transit is assessed on different environmental conditions and tide stages to evaluate the safe transit windows in operation.

    Opis:
    Approaches to the port are usually considered high traffic areas. Not only deep draft vessels pass through this limited manoeuvring space, but also intensive pleasure craft traffic, especially during the summer season. Crossing of both commercial ships and pleasure craft traffic may generate dangerous situations for navigation. The aim of the following article is to present solutions to the aforementioned safety problem. The article focuses on the navigation safety aspects at the Świnoujście seaport entrance. Currently, Świnoujście-Szczecin Port Regulations take only large ships into consideration while specifying the safety passing at this area, at the same time, belittling the presence of small crafts up to 20 m in length. In order to prove the need for change, one should first present the necessary research concerning the evaluation of the safety level of maximum sized ships navigating at the Świnoujście entrance area in the presence or absence of small pleasure crafts. The surveys were conducted on a group of pilots and captains possessing pilot exemption certificates. The research findings clearly show that the traffic of small crafts and large ships should be separated due to safety concerns. Thus, marine traffic engineering solution is suggested in order to eliminate the most plausible dangers.

    Opis:
    The increasing sizes of ships and lack of functionality of the existing solutions determine the interest in rebuilding the already existing solutions. Simulation models allow to analyse the possible modernisation variants taking into account the variability of elementary parameters. The article presents analysis results for the Przemyslowy Canal in Szczecin with respect to navigation safety and regulating traffic regulations in the Przemyslowy Canal taking into consideration the interests of all subjects involved. The paper applies real-time simulation methods based on manoeuvring simulators. After a thorough analysis that took into account the safety of navigation, further possibilities of development have been determined. Study results are aimed at designing new solutions in case of modernization of the Przemyslowy Canal in Szczecin.

    Opis:
    The paper presents a study on the environmental impact on the risk of harbour operations. The hydro-meteorological elements have been recognised as the most important safety factors with regard to the ship entrance into the harbour and berthing inside the docks. They are identified as real time, short and long term factors and they all should be considered in the safety assessment of harbour operations. The risk of each operation should be determined on the basis of weather forecast and the modelled prediction of the total water level, surface currents and waves. Several topics have been discussed in the paper with regard to the safe ship approach and navigation inside the harbour. The application of different tools for the prediction of ship performance is presented. The stochastic method for the determination of probability that the ship will navigate within the boundaries of the required navigational width and low speed manoeuvring standards proposed by Panel H-10 SNAME have been considered. The real scale experiments carried out in Port of Gdynia and the several trials performed using the Full Mission Simulator convinced that the open water model tests are necessary for the proper prediction of ship performance during berthing. The program of the proposed open water investigations is presented in the paper. The experimental stand constructed for the tests of ship-berth interactions, in the lake Silm at the Ilawa Ship Handling Training and Research Centre facilities is described.

    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.
