The paper contains results of a numerical simulation of maneuvering of a ship in restricted waters. Main goals of the research presented were development of method of forces and moments prediction and elaboration of criterions of maneuverability of a ship. Results of numerical computations were presented and compared with results of experimental measurements. There were made regression analysis to find dependences allow taking into consideration additional forces and moments appeared on ship’s hull while maneuvering nearby banks. With the help of these formulas additional forces and moments for several ships were calculated. There were several simulations in training simulator “Polaris” to validate the formulas.

It seemed that the commissioning in 1990 the first open top container ship "Bell Pioneer", prompted a boom of building of the new architectural-constructive type vessels. Several shipping companies bought for its fleet a series of open containerships. But after ten years have seen a slowdown in the building of the open containership. But despite the changes in the organizational and technological scheme of linear container carriage, the hatchless container ships have found their niche in the feeder transport sector. The article provides a state of act and development of open top containerships.

The mathematical model and numerical algorithm for analysis of a ship dynamics on waves are presented. The storm waves is simulated by a setting of wavemaker motion. Numerical integration of a motion equations is executed by a Runge-Kutta method. The potential fields of a water velocity and acceleration in each time step are determined with using of a boundary element method and with sampling of all boundaries (wetted surface of a ship, free surface of water and surface of a wavemaker). The iterative procedure of acceleration potential correlation is applied for correct accounting of a conservation law of hydrodynamic equilibrium.

The article considers a process of formation of the subsets of the qualitative attributes which define construction of the family of the terminological subsystems of the reliability theory and the subsets of models of status transitions followed by change of the priority of the current status of the classified object. The formed subset of the models of the terminological structures features a number of alternative categories of notions like «property + property → process» formed on the subset of mating tops of the subgraphs, which form the content of the system generic notion reflected by the notion of «subject» category. The article provides an analysis of construction of the family of the  subgraphs of the status transitions, which identify the crossing of the mating contours of the one-level model of the graphs of main statuses and events on which subset of the mating tops the priority of a group of attributes reflected by the content of mating notions is changed..

Key words: model of status transitions, terminological subsystem of the reliability theory, subset of mating tops of the subgraphs, the one-level model of the graphs of main statuses and events, priority of a group of attributes.
