Mai B. Increase of accuracy of process of a divergence of ships in the constrained conditions

Problem of reduction in breakdown susceptibility of ships from their collisions is considered, the problem of the analytical description of process of a divergence of courts in particular is solved at absence of navigating dangers. The way of the account of constraint of area of maneuvering is received at a divergence of vessels courts which differs that at an estimation of danger of collision and a choice of safe optimum maneuver of evasion safety zones of elliptic and rectangular forms are used that raises profitability of maneuver. The algorithm of calculation of optimum maneuver of a divergence which has formed base for development of imitating model of process of a divergence dangerously approaching ships is synthesized. This model is submitted by the computer program, allowing to model process of a divergence of ships. Results of development of imitating model and modelling with its help of process of a divergence have allowed to receive recommendations on increase of safety of maneuver of a divergence of ships. These recommendations, first of all, concern practical interpretation of some aspects international regulations COLREG 72.
