Planning of motion coordinates and maneuvering control of a marine vessel when anchoring under cybernetic risk

Abstract

When performing voyage cycles of a marine vessel, one of the most common maneuvering operations is anchoring. A feature of this operation is the requirement for its execution in a strictly defined place by the port of call, as a rule, in an outer roadstead open to the action of the wind, in which the direction of the current is not always known. In addition, in addition to navigational risks, cybernetic risks have also appeared. Being different in the nature of their occurrence from navigational ones, they have the ultimate goal of causing a navigational accident, causing significant damage to the vessel, leading to the loss of cargo or financial losses to its ship-owner. The basis for the formation of meaningful and mathematical models of maneuvering during anchoring is the graphical method of displaying the coordinates of movement in an inverse way, the method of preparing a table of waypoints and calculating maneuvering parameters. When preparing for the ship's voyage cycle, using the table and data on maneuvering characteristics, the certified computer program «Path Planning IS» automatically calculates the matrices of coordinates of trajectory points and stores them in a navigation cluster protected from cyber-attacks. These data are used only after arriving at the anchorage, during the influence of cyber-attacks or for anchoring under normal conditions. It has been established that this method of planning the coordinates of the path during maneuvering for anchoring and storing data in a navigation cluster protected from cyber-attacks during the voyage allows organizing navigational cyber security. The theoretical aspect of the research allows us to assert that the decisive role in the formation of the competence of practicing ship-owners is laid in the methodology of using digital automated complexes and training manuals, which ensures the training of the ship's crew for work in conditions of cybernetic risks and the organization of navigational safety of maneuvering when anchoring.
