Abstract

Despite considerable efforts and resources, expended on soft-, hardware and organizational facilities for navigators’ development, it is required to increase the level of navigators’ skills, familiarize them with the functions and limitations of ship’s equipment. Building a harmonized cooperation between the members of bridge team is one of the most important tasks even for the well-educated and skilled in ship handling officers. A problem of sea transportation safety improvement through increased quality of navigators’ simulator training is considered in current article.  A critical review of IMO model courses and their use for the tasks of navigators’ simulator training was performed. These recommendations pursue the purpose of standardization and unifying the bridge team training in accordance with STCW 1978/ 2010 convention. The main navigational tasks were classified, their formalized form end solutions represented. Because time constant and time of delay do not depend on the decision’s responsibility level, it is possible to consider them as the characteristics of a definite Bridge Team member. These descriptions are determined by the simple experiments of reaction on the known signals and it is possible to get the model of Bridge Team behavior depending on the decision-making risks and external indignations. It was suggested to use safe sailing probability function as the criterion of navigator’s competence. The essential point in the article is the transition from partial criteria for evaluating the navigators’ work to the assessment of the average risk as a single criterion, which makes it possible to assess objectively the prospects of using a definite vessel crew. The implementation of a risk minimization strategy leads to a sequence of steps which allows to achieve an optimally safe trajectory. It was suggested to use Pontryagin’s maximum principle on an optimum route plan,   thus the task turned to the standard task of optimum operation speed of the linear system. A structure of optimal solution for bridge team simulator training is defined. A training complex structure consisting of visualization complex, where an external situation is designed, Bridge Team members’ workplaces, data bases of vessels’ dynamics models, navigation database, bases of indignations models and instructor’s workplace was suggested.
