DEVISING AN APPROACH FOR THE AUTOMATED RESTORATION OF SHIPMASTER’S NAVIGATIONAL QUALIFICATION PARAMETERS UNDER RISK CONDITIONS

Abstract

The object of this study is the safety control system of ship management, by identifying and restoring the qualifica tion parameters of shipmasters in criti cal situations. The task solved in the study is the timely determination of an insufficient level of qualification for the perfor mance of certain operations in con trolling the movement of the ship, by applying a formal-logical model of de tecting the intuitive actions of the ope rator-shipmaster and gradually restor ing his/her qualification parameters using the devised method. The stages of development and the formal-logical structure of the model and method in terms of cognitive auto mation were described in detail as the study results. It was possible to ensure early detection of risks when controlling the movement of the ship in 56 % of cases, during a laborato ry experiment on simulators, which in 24 % of cases turned out to be particu larly dangerous. The interpretation of the results in volved algorithmizing complex and for malized data on the actions of opera tors and the application of the method of restoring their qualification para meters, which allowed a comprehensive approach to safety management. The distinguishing features of the findings were to predict the level of danger by simulating maritime opera tions with input navigational and indi vidual conditions. This made it possible to improve the effectiveness of ope rations to 89 %, reduce the phenome non of loss of control over the course to 32 %, reduce critical situations to 7 % and the cost of resources. The scope and conditions of practi cal use involve a comprehensive assess ment of external and internal influ ences on the level of danger, delay in decision-making by operators, as well as sailing conditions. The simulation results could be used to devise strate gies for planning maneuvers, predicting risks, and developing maritime securi ty systems
