Abstract

A conceptual modernized model of route planning during the voyage cycle of a sea vessel has been developed. It differs from the existing change in the method of planning the transition by trajectory points, taking into account the manoeuvrability characteristics, the water area for manoeuvring and the introduction of the stage "Risk Analyzer". Planning by the method of advanced content model and presentation of results by the summarized matrix of trajectory points (TP), after risk analysis, allows you to develop measures to manage the level of risks and maintain them at an acceptable level. As a result of accident studies in the areas of the Bug-Dnieper-Lyman Canal and Kherson Sea Canal and comparison with the Turkish Straits, it was found that navigation risk factors are the same – grounding, collisions in the canal, onslaught or other vessels, ice cases, technical reasons (failure of the main engine). Therefore, measures for voyage planning and preparation for navigational risk management will be the same for any region. The algorithm of planning by the method of the advanced content model allows the establishment of the cause of navigation risk and assumes the use of data for the vessel’s condition in real time. To reduce the risk of stranding, high-precision planning of trajectory points, automatic control of the amount of lateral displacement and the introduction of the correct reserve of water depth under the keel. Continuous automatic control of the bandwidth, by calculating the abscissa of the pole of rotation, prevents landing on the shoal and collision with the wall of the canal, fairway or ship at the berth. Keywords: vessel’s manoeuvrability characteristics, route planning by trajectory points, summarized matrix of voyage coordinates, navigational risks analyzer, acceptable risk management.
