Gabruk R. The methodology of guaranteeing dynamic positioning safety by definition a comprehensive reserve of controllable thrusters reactions.

In the thesis was created a new methodology for quantifying the safety of navigation of water transport object, carrying out dynamic positioning in locally confined space of technological work in non-linear dynamic influences of environmental factors. The methodology based on new integrated paradigm of prediction coordinated interactions of components which forms dynamic positioning system. Implementation effects of proposed methodology are based on the analysis of complex models that form the knowledge base. The comprehensive reserve of controllable thrusters reactions was adopted as quantitative characteristic of dynamic positioning safety. The developed methodology uses two-sided algebraic transformations of non-linear models, which are components of complex interacting systems, to provide information regarding safety of dynamic positioning to operator. Dynamic positioning safety assessment should be carried out by analyzing thrust reactions reserve polar diagrams for non-linear determined in time disturbing influences of environmental factors. Diagrams make possible to define sector of safe courses for dynamic positioning, escape routes and optimize dynamic positioning of water transport object. The efficiency of methodology, models and methods were proved scientifically by computer simulation and experimental results.
