Abstract: Navigational equipment and systems installed on board ships and at land-based centres improve and automate the processes of navigational information acquisition, processing and presentation. These systems perform mainly information functions that enhance decision making processes. The growing range and amount of available information and the consequent difficulties in data processing and use make up a potential source of human errors, one of the main reasons behind marine accidents. Actions already undertaken aim at extending the existing navigational systems, or building new ones, where decision support functions will have a wider scope. This article will describe the present situation and directions of developing navigational systems in maritime transport.
Efforts to ensure the safety of people, ships, cargo and the marine environment and to enhance the effectiveness of transport services in maritime shipping result in increasingly updated navigational equipment and systems implemented on board ships and in landbased centres. These new facilities, widely using advanced information technologies, support decision making processes. Basic functions of decision support systems include acquisition, storage, processing and presentation of navigational information.
As the user’s needs are diverse in terms of scope and form of navigational information to be presented, dedicated systems are being created. These include, but are not limited to pilot navigational systems, docking systems, weather routing systems and dynamic positioning systems.
Available computing power continues to grow, consequently more and more complex computing methods and algorithms can be introduced, extending the range of functions of navigational systems presently in use. This refers to issues such as vessel movement predictions, generation of solutions to an existing situation with the justification of the solutions generated by the system. Developments we can observe tend to gradually
transform navigational information systems into decision support system utilizing methods and tools of knowledge engineering. (...)
