Kalinichenko G. Perfection of methods of divergence of ships by the account of their dynamics and navigation obstacles. It is Qualifying scientific labor on rights for a manuscript

The minimum dynamic system is considered in work, current status of which depends on the managing influencing of both ships. Its formalization is conducted and got analytical expressions of mutual dependence of parameters of veritable and relative motion. Situation indignations, which arise up at dangerous rapprochement of ships and can take on two values which determine the standard and urgent maneuvering, are considered. The concept of region of dangerous courses of the minimum dynamic system is resulted and considered its use for the choice of safe maneuver of divergence by the change of courses. In work the question of account of inertia is considered at the turn of ships and navigation dangers in the district of their maneuvering at forming of region of dangerous courses of ships. It is shown that through inertia of ships at their turn distance of the shortest rapprochement appears less calculation, therefore at construction of region of dangerous courses of its border settle accounts for maximum - possible distance of rapprochement, which is megascopic on the size of loss of distance of the shortest rapprochement through inertia of ship. The account of navigation dangers is considered at the choice of maneuver of divergence of ships by the region of dangerous courses. Got expressions for the calculation of maximum courses of deviation of ships at presence of different types of navigation dangers: point, distributed linear and difficult distributed. The reflection of maximum courses of deviation is shown together with the regions of dangerous courses and developed procedure of choice of safe courses of deviation of ships for divergence taking into account limitations which arise up through the presence of navigation dangers. For verification of correctness of the method of choice of safe maneuver of divergence got in dissertation work the considered imitation computer program, its description is resulted, and also represented the results of imitation design of processes of correct divergence of ships in different situations of dangerous rapprochement. Keywords: safety of navigation, warning of collisions of vessels, region of dangerous courses, navigation dangers.
