First, we especially focused on Uchida-Kraepelin performance test (hereinafter, referred to as UK-Test) in order to check the ability of non-technical skills of the officers in charge of a navigational watch (hereinafter, referred to as OICNW). UK-Test is one of the psychological test for understanding the personality. In this paper, we considered whether UK-Test is effective methods for OICNW in order to check the ability of non-technical skills using UK-Test results and collision avoidance manoeuvre experiments results on the ship handling simulator (hereinafter, referred to as the simulator). Specifically, we analysed the correlation between UK-Test results and collision avoidance manoeuvre experiments results on the simulator. We also created the collision avoidance scenario that required a lot of the ability of non-technical skills as OICNW, and evaluated the ability of non-technical skills of OICNW.

Safe shipping is essential for society and different measures are taken to improve maritime safety, for example through implementation of traffic separation schemes, radar surveillance and traffic management concepts. But how can maritime safety be measured to determine the effects of those implementations? In this study, a real-time maritime safety index for a ship is developed, taking into account both the probability of grounding and the probability of collision. The index is developed using fuzzy integrated systems and validated in ship handling simulator scenarios. It uses numerical data from the simulator as an input to assess the present traffic situation from the perspective of a specific ship and outputs a comprehensive index. This paper describes the concept of sea traffic management as proposed and evaluated in the EU funded STM Validation project, the motivation for developing a maritime safety index, the numerical input variables and model properties and also validates the feasibility of the approach.

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.

The hydrodynamic interaction effects between two vessels that are significantly different in size operating in close proximity can adversely affect the safety and handling of these vessels. Many ship handling simulator designers implement Potential Flow (PF) solvers to calculate real-time interaction effects. However, these PF solvers struggle to accurately predict the complicated flow regimes that can occur, for example as the flow passes a wet transom hull or one with a drift angle. When it comes to predicting the interaction effects on a tug during a ship assist, it is essential to consider the rapid changes of the tug’s drift angle, as the hull acts against the inflow creating a complicated flow regime. This paper investigates the ability of the commercial PF solver, Futureship®, to predict the accurate interaction effects acting on tugs operating at a drift angle during ship handling operations through a case study. This includes a comparison against Computation Fluid Dynamics (CFD) simulations and captive model tests to examine the suitability of the PF method for such duties. Although the PF solver can be tuned to solve streamline bodies, it needs further improvement to deal with hulls at drift angles.

Simulators have proved beneficial for ship handling training in real time on well equipped bridges throughout the last decades. The Maritime Simulation Centre Warnemuende (MSCW) has been com-plemented by a new type of simulator called the Safety and Security Trainer (SST). Wismar University has been involved in the conceptual design and development of this new technology. One of the most challenging innovations developed during the research is the 3D-designed RoPax ferry “Mecklenburg-Vorpommern” for the SST simulation system. An integrated support and decision system, called MADRAS, was interfaced into the SST and the entire system was interfaced to the Ship Handling simulator SHS in order to assists officers in coping with safety and security challenges during manoeuvres of the vessel (SHS). This new and enhanced simulation facility allows for “in deep” study of the effects of the safety and security plans and procedures on board and enable more detailed evaluation of their effectiveness under varying conditions and during different courses of events by a different series of simulation runs. This paper will introduce the basic concept of the safety and security training simulator and describe the work entailed for its integration into the complex envi-ronment of full mission ship-handling-simulators. Selected results of a case study dealing with first basic im-plementation of training scenarios will be demonstrated.

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.

This paper presents development of and experience from a simulator based training course for personnel in Norwegian emergency response operations. As a response to governmental white papers on emergency preparedness and safety at sea in Norwegian waters, it was decided to develop a simulator based training course with focus on emergency towing operations. The first part of the paper describes work done by a group of subject matter experts appointed by Norwegian Coastal Administration. This group assisted Ship Manoeuvring Simulator Centre to specify the content of a three days training course for deck officers on emergency response vessels. Two test courses were run in the summer of 2006. Feedback from these courses was used to update and extend course content for the first ordinary courses that took place later that year. The second part of the paper reviews course experience and feedback from course participants. The final part of the paper describes the links between the simulator based course and the research and development activities in the R&D project “Arctic Emergency Operation” involving partners from France, Germany, Japan, Norway and United Kingdom.

Nowadays the equipment used on ships is becoming more and more sophisticated, safety of shipping depends heavily not only on trustworthiness of high-tech products, but also on mariners’ competence. It is necessary to find methods to enable seafarers to keep track with technical developments. Simulators as a tool combined with a properly developed course curriculum and qualified instructors provide an appropriate method not only for training, but also for measuring, assessing and evaluating individual mariner performance in order to test levels of competency and proficiency. According to Nieri (1995, p. 1/6), “The development of performance-based assessment tools would utilize the widely-recognized advantages of simulators and part-task trainers to generate a scenario in which the license candidate must demonstrate his knowledge of system relationships, knowledge of operational procedures, monitor systems and situations, respond to unexpected occurrences, identify and diagnose problems, and manage personnel, in a dynamic world“. This paper discusses the usage of new capabilities of the NTPRO 4000 full mission ship handling simulator in the assessment and evaluation processes at Lithuanian Maritime Academy.

International sea transport has growing rapidly during the period of the last decade. Ships became larger and wider and its container capacity is still increasing to 12.000 TEU and even more. To navigate such vessels safely from port to port and specifically within the ports more and more enhanced computer-based systems are installed on the ships navigational bridges. Prediction tools are very helpful and already in use on ships for a long time. However, the simplification of existing predictions allows restricted use only and do not include the immediate response on changes of rudder and engine. Within this paper investigations into the feasibility and user acceptance of newly developed layout of navigation display will be introduced and selected results of simulation studies testing the influence on manoeuvre performance dependent on different kind of prediction functions will be discussed. Examples will be given for results from test trials in the full mission ship handling simulator of the Maritime Simulation Centre Warnemunde and a concept for the application of the developed .tools for purposes of collision avoidance is described.

Ship maneuvering models are the keys to the research of ship maneuverability, design of ship motion control system and development of ship handling simulators. For various frames of ship maneuvering models, determining the parameters of the models is always a tedious task. System identification theory can be used to establish system mathematical models by the system’s input data and output data. In this paper, based on the analysis of ship hydrodynamics, a nonlinear model frame of ship maneuvering is established. System identification theory is employed to estimate the parameters of the model. An algorithm based on the extended Kalman filter theory is proposed to calculate the parameters. In order to gain the system’s input and output data, which is necessary for the parameters identification experiment, turning circle tests and Zig-zag tests are performed on shiphandling simulator and the initial data is collected. Based on the Fixed Interval Kalman Smoothing algorithm, a pre-processing algorithm is proposed to process the raw data of the tests. With this algorithm, the errors introduced during the measurement process are eliminated. Parameters identification experiments are designed to estimate the model parameters, and the ship maneuvering model parameters estimation algorithm is extended to modify the parameters being estimated. Then the model parameters and the ship maneuvering model are determined. Simulation validation was carried out to simulate the ship maneuverability. Comparisons have been made to the simulated data and measured data. The results show that the ship maneuvering model determined by our approach can seasonably reflect the actual motion of ship, and the parameter estimation procedure and algorithms are effective.

Constantza Maritime University had won a two year research grant, financed by the Romanian Government through the National University Research Council, for optimization of the Constantza port fairway and assessment of maneuvering procedures for handling of very large ships. The actual port fairway could not ensure safe navigation for ships with a draught greater than 13 meters, and also in the container terminal area, the actual maximum depth is 11meters. In a port without tide, the unique solution is to deepen and enlarge the existing fairway. The aim of our paper is to present the working hypothesis and methodology, which we used for creating the ship handling simulator maneuvering scenarios for very large ships. Validation and assessment of these scenarios, in order to establish the optimum shape and dimensions of the redrawn fairway, were done in cooperation with Constantza port pilots and VTS operators.

This paper investigates vessel traffic risks that are exposed by a new port installation. A vessel traffic risk analysis was performed by the Ship Handling Simulator team for container terminal installation in Izmit Bay. The main purpose is to evaluate whether the container terminal project shall affect the proper operation of nearside Oil Refinery Terminal. Construction and revision of shore structures may form significant threats for masters in ports and narrow waterways. The Ship handling simulator of ITUMF presents the environmental objects’ effects, vessel traffic and weather conditions. Furthermore, the Environmental Stress Model of Inoue (2000) may give an opportunity to analyse vessel traffic risks quantitatively by SHS.

In the present paper, a safety evaluation index that determines the probability of accident occurrence of collision and stranding when the experiment is executed using a ship handling simulator is proposed, by noting Unsafe Ship Handling Situations. The number of Unsafe Ship Handling Situation was counted from the results of simulator trials, and the accident ratio was surveyed from the past records of sea casualties in the corresponding water area. The correlation between the appearance ratio of Unsafe Ship Handling Situation and the accident ratio showed reasonable coincidence with the order of 10-3. When port administrator tries to assess the effectiveness of safety improvement planning of port and harbour facilities, it can be said that this kind of probabilistic prediction model of accident occurrence is indispensable from the aspect of introducing cost effectiveness analysis.

This paper deals with a method for identifying the main parameters of a maneuver using both real-time full mission simulators and positioning data obtained from the Automatic Identification System of the same area. The effort required for experiments in real time maneuvering is naturally larger than the effort required to collect already available data. Analysis of both data sources is presented. We show how the curvature of the ships track can be related to the wheel-over point and further used to estimate the main parameters of a course-changing maneuver. The southern approach to the Risavika harbor in the southwest of Norway is used as a demonstration. The approach angle and turning circle diameter was accurately identified in both AIS and simulator data, but significant navigational markings was only quantifiable in simulator data.

Stosowanie symulatorów manewrowych stanowi obecnie normę w szkoleniu. Wiemy od dawna, jak je wykorzystywać i jak przygotowywać właściwe ćwiczenia, które byłyby bliskie rzeczywistym sytuacjom na morzu i gwarantowałyby realizację celów szkolenia. W obecnych czasach instruktorzy symulatorów coraz częściej zwracają uwagę na sam proces obiektywnej, wielokryterialnej i automatycznej oceny umiejętności nabytych podczas szkolenia na symulatorach (i/lub egzaminowania). Ciągle nie mamy akceptowalnych kryteriów i metod oceny umiejętności. W pracy przedstawiono rozważania na temat czynników umożliwiających taką ocenę, które oparto na badaniach oceny manewru podejścia statku prawą burtą do nabrzeża w celu zacumowania, wykonywanego na symulatorze manewrowym.

Using shiphandling simulators (full-mission or PC-based) is now a standard for training, We know how to take advantage of them and how to prepare good exercises as close to real situations at sea as possible, and training goals. Now, the shiphandling instructors more and more often discuss the problem of objective, multicriteria, and automatic shiphandling skills assessment (and/or examination) also through the use of shiphandling simulators. There are still no accepted criteria and methods in this respect, though the shiphandling simulator training itself has been intensively practised for a few decades over the world. The present paper contains discussion on such possibilities with regard to shiphandling skills assessment. The basis of discussion is research of ship's starboard side approaching to the pier for berthing assessment.
