    ABSTRACT: Within this paper results of ongoing investigations will be presented. Main subject of studies is laid on the present situation of alert management onboard ships navigational bridges and potential use of data recorded with mandatory ship-borne VDR equipment during normal ship operation to support the process of on board collision avoidance. The investigations and results discussed and presented in the paper are gained within trhe work in two different projects on research and technical development

    The development of training and practice of navigation for advanced ships : application to merchant marine training centre programmes in Thailand

    Get PDF
    This dissertation is a study of an advanced ship, focusing on the training needs for a navigation officer by taking into consideration technological advances, operational factors and human factors. A short overview is given of current and future trends, and developments in modem technology in shipping including an advanced bridge in the form of an integrated bridge system. The role of the navigator, bridge operational procedures and conditions, and training needs are examined, taking into account manning and technological change that have taken place. The required knowledge, skills and attitude for an operator of advanced ships are identified. The importance of Bridge Resource Management training is also discussed. The factors influencing the operation of the advanced ship under the concept of oneman bridge operations are investigated. The results are evaluated to further improve the safe and efficient operation of an advanced ship. Proposals and recommendations are made to improve the training programmes, technology and operations for advanced ships and to update the navigation training programme at the Merchant Marine Training Centre (MMTC). A number of recommendations are also made concerning the need for further study and investigation in the subject

    How a ship´s bridge knows its position - ECDIS assisted accidents from a contemporary human factors perspective

    Get PDF
    The technological artifacts used in ship navigation have undergone substantial changes during the last decades, and real-time digital navigation is a reality with the introduction of the ECDIS. Despite the obvious merits of this new navigation mode, and the imagined improvement in safety that it theoretically should bring, ECDIS has in recent years been associated with several accidents. The term ECDIS assisted accidents has emerged in official accident investigation reports and is widely used among the applied technology community as well as having led to the term reverberating the RADAR assisted accidents that the maritime industry has used following the introduction of the RADAR. Despite the focus on the causal contribution from the interplay between the ECDIS and the navigator, the conclusions in the official accident investigation reports are predominantly directed towards the abilities of the ECDIS operator to use the equipment properly, and to a lesser extent on the features of the ECDIS. The reports do not at all investigate how the equipment could have helped navigators, by offering better support in reaching their contextual goals, i.e., to remain in control of the ship and to maintain safe navigation. Parallel accounts emanating from the applied community of ship navigation seem to suggest that functioning of the ECDIS is far from perfect, and at times is considered suboptimal by navigators. The ambition driving this thesis work was to explore these second stories about navigation with ECDIS, based on operator experiences, in order to gain leverage for new ways to inform future development and design of ECDIS, which to a higher degree would need to take into account the contextual conditions and demands that operators experience in the field of practice, and thereby to minimize the gap between how designers, and other remote stakeholders, imagine ECDIS operations, and how these actually play out. Naturalistic research was carried out by attending three ships ́ bridges while the ships were operating. Insights were gained into what sometimes make work difficult during navigation by ECDIS. The findings were juxtaposed with information found in three official accident accounts of ECDIS assisted accidents, and finally the results were discussed based on a theoretical framework based on contemporary human factors and systems safety research literature, including Cognitive Systems Engineering. Thus, it was concluded how the methods applied in this thesis work, and its findings, could be useful to future ECDIS design and development

    Impact of automatic identification system (AIS) on safety of marine navigation

    Get PDF
    Automatic Identification System (AIS) was introduced with the overall aim to promote efficiency and safety of navigation, protection of environment, and safety of life at sea. Consequently, ship-borne AIS was implemented on a mandatory basis by IMO in 2000 and later amendments to chapter V of Safety of Life at Sea (SOLAS) Convention. Therefore SOLAS Convention vessels were required to carry AIS in a phased approach, from I" July 2002 to end of December 2004. The intention is to provide more precise information and a clear traffic view in navigation operations, particularly in anti-collision operation. This mandatory implementation of AIS has raised a number of issues with respect to its success in fulfilment of the intended role. In order to improve the efficiency of the AIS in navigation operation, this research mainly focused on the accuracy of AIS information, and practical use of the technology on board the ships. The intentions were to assess reliability of data, level of human failure associated with AIS, and the degree of actual use of the technology by navigators. This research firstly provided impressions about AIS technology for anti-collision operation and other marine operation and, about a system's approach to the issue of human failure in marine risk management. Secondly, this research has assessed reliability of AIS data by examination of data collected through three AIS data studies. Thirdly, it has evaluated navigators' attitude and behaviour to AIS usage by analysing the data from navigators' feedback collected through the AIS questionnaire survey focused on their perceptions about different aspects of AIS related to its use. This research revealed that some aspects of the AIS technology and some features of its users need further attention and improvement, so as to achieve its intended objectives in navigation. This study finally contributed in proposing the AIS User Satisfaction Model as a suitable framework for evaluation of navigators' satisfaction and extent of the use of AIS. This model can probably be used as the basis for measuring navigators' attitude and behaviour about other similar maritime technologies
