Method and system for supporting the navigation decisions, in the process of safe piloting of the navigable object

摘要

A method and system of navigational decision support in the process of safe vessel navigation is provided in this invention. The method has a number of characteristic features: we receive signals identifying our ship (own ship) and targets from navigational systems and equipment, then, after the integration of these signals, we analyze and assess a present navigational situation by means of a computer and display the situation. If own ship faces a risk of collision, we generate allowable and recommended manoeuvres of own ship or targets and we graphically display them to a navigator; in the proposed manoeuvres we take into account at least one safety criterion as well as criteria representing good marine practices or economical criteria. Subsequently, upon navigator's approval of the proposed manoeuvre/s, we perform either one of the allowable or recommended manoeuvres or a series of such manoeuvres. After navigational data collection, we submit them to the processes of fusion and integration, using a computer and specialized software. The system of navigational decision support system in the process of safe vessel navigation, incorporating the modules of data collection, event identification, knowledge base, analysis and assessment of a navigational situation, manoeuvre generation, movement prediction, graphical user interface (GUI), management and execution, is characterized by the following: the data collection module contains a fusion block, and the knowledge base module contains a block of algorithmized Collision Regulations and a block of criteria based on good marine practices. The execution module controlling the work of own ship's machines is connected with the autopilot, steering gear, main engine, telegraph and controllable pitch propeller.
