This article presents a dedicated kinematic method of determining a safe fairway bend width with a specific turn angle and arc radius as the function of ship parameters and prevailing navigational conditions on the fairway. The assumed approach takes into consideration monoeuvring and navigational components of the safe fairway bend width. The method is based on an analysis of the results of numerical tests conducted on a model representing all physically possible movements of ship's centre of gravity in the bend. The developed method was initially verified on the Ińskie bend, part of the Świnoujście-Szczecin fairway.

The paper presents the processing of EGNOS integrity data received either directly from the satellite network or the Sisnet internet relay. Relationship between the individual frames in EGNOS messages has been described. Usefulness of these data was indicated by the three examples. In the first example data form EGNOS was used to compare integrity parameters and the calculated position error. In further examples the simulated position with error and calculated integrity parameters were implemented together. The results were presented in two ways: with use of dedicated program which presents only ship contours (the one not covering GNSS uncertainty and the one covering this uncertainty called Marine Vessel Protection Area) and as a layer in existing ECDIS.

During the process of development of the Full Mission Bridge Simulator, I have come in to a conclusion that an important part of a successful learning process is the ability to train with a high fidelity bridge simulator. The Polar areas are harsh environments and to survive there, one must have special training and experience. This surviving means that the polar ecosystem will survive from pollution and the vessels and their crew from the bad judgments or misconduct of vessel operators. The most cost-effective way to improve special skills needed in the Polar waters is to include bridge simulator training to the Deck Officers requirements. In this paper I will introduce a real life situation in which an icebreaker assisting a merchant vessel gets into a “close call” situation and how this was handled. Maritime industry hasn’t studied much about the influence simulator training has to the navigators. Here the maritime industry could learn from aviation and medical industry, since they have done some extensive scientific studies to prove the need for simulators.

In parallel with the increase in the volume of world trade, cargo handling rates and seafarers' pace of work has increased. Although the STCW regulations and restrictions on working hours has improved, this tempo has brought with it insufficient resting hours, especially in short sea transport. It is known that individuals under stress and intensive workloads are more prone to making mistakes due to fatigue. In this study, the officers’ working hours are simulated in full-mission simulator at short sea transport to investigate errors made during the navigation and port watches. For this purpose, the data were obtained from 7 volunteers watchkeeping officers with the help of video monitoring and check lists in the full-bridge simulator system and also, system records in cargo handling simulator. With this study, introduced what types of errors made during navigation and port watches by watchkeeping officers under the intense pace of work. And the errors are evaluated under the legislation of international maritime. As a result, to comply with the limitations of working hours, it is necessary to increase the number of officers responsible for operations on short sea transport.

The primary purpose of a marine casualty investigation is to seek to establish the causal factors of the casualty with a view to learning the hard lessons and avoiding a repetition. The broad questions of an investigation: ""who?, what?, when?, where?, why?, and how?"", all help to uncover the facts. The investigation sequence will cover a diverse range of fact-finding activities, amongst which, as often the case, may be a requirement for “conducting specialised studies”. Following the fact-finding stage the typical investigation progresses to analysis of the facts, reaches conclusions and makes recommendations. Keeping an open mind, to avoid premature conclusions, requires the separation of the fact-finding and analysis phases. But the analysis may well help to identify missing pieces of evidence, or different lines of enquiry that may otherwise have gone undetected. As an effective reconstruction tool, a full-mission bridge simulator offers an opportunity to examine a broad spectrum of environmental conditions and vessel characteristics, as well as equipment failures, human factors and operating procedures. A casualty incident can be reconstructed in a real-time simulated environment, to aid more detailed analysis. Within the usual confines of the legal process, comprehension of nautical ‘black magic’ is greatly simplified for non-mariners, by seeing the simulated casualty incident unfold, in real-time or in selected short-time segments.

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.

This paper proposes an approach of measuring navigation performance using a full mission bridge simulator. The motivation for this research is the updates in equipment and that the desire of using new instruments and technology not always is accompanied by analyses of the impact of the changes. The task of navigating in a fairway is proposed to be assessed through various methods to answer questions related to performance and the experience of using bridge equipment. The overall aim is to reach a higher degree of understanding and knowledge through the testing of different instrumentation setups.

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.
