The article presents the analysis of accident rate of ships of internal and mixed «river-sea» and sea navigation. Different types of ship-repair companies are looking in this article. Also looking the specificity of their activity. On the basis of the analysis of the existing problems in the field of organization and technical planning of the ship repair production proposed the concept of a new product. It aimed at solution of the same problems.
Key words: Ship-repair company, planning of ship-repair works, the software product, the fleet passport.

This work presents the example of design of the filter with the final impulse characteristic for a filtration of a useful signal from high-frequency set with noise. The created filter is applied to the analysis of the signal which has been written down by accelerometers, established on the case of the one-stage centrifugal pump. Quality of the filtered signal is investigated.
Key words: Signal processing, filtration of a useful signal, spectral characteristics, ship pumps.

This paper is about  the three dimensional potential problem of the longitudinal  motions of a ship in the canal of restricted depth. Numerical panel’s method and the method of mirror images are used  for the solution of this problem. The investigation of the influence of the breadth of a canal on the added masses and damping coefficients, exciting forces and amplitudes of ship motions is given. Also, the comparison of influence of a quantity of vertical walls on those values is presented.
Key words: canal of restricted depth, method of mirror images, Green function, added masses of a ship, damping coefficients, motion responses.

The results of numerical simulations of the ship motions on the still water, heave and pitch motion of the Wigley Body are presented. The Reynolds averaged Nevier-Stokes equations coupled by k-ε and SST turbulence models are used. The Volume of Fluid method is applied for the estimation of the surface elevation. The 6DoF method is used to describe a ship translation. The modified solver of OpenFOAM has been developed. The ship resistance and parameters of the heave and pitch motions are compared with experiment.
Key words: roll, waves, viscous fluid, turbulence.

The article describes the method of uniformly cooling of space between fuel assemblies with a slit water-water injector and a perforated shield. The formulas are given. A schematic diagrams of an apparatus used for cooling of space between fuel assemblies are shown. The paper presents the computational and theoretical analyzes of the undiffuser water-water injector and a perforated shield in inter-channel space, allowing to achieve uniform cooling of the reactor core to the steam-producing device such as "Beta".
Key words: integral reactor, cooling of the reactor core, boiling water reactor.

The present paper contains a brief overview and analysis of the currently used terminology applied for the mechanization and automation of organizational and technological processes, enterprises, vessel, ship (water, air and space), as well as methods for determining the assessment of these processes and their compliance with the current development level of science and technology. There are many different interpretations of these terms, which do not always reflect the views of experts in these professional fields. Here we  review the most well-known definitions are and introduce our own approach to the assessment of the appropriate levels and degrees.
Key words: a terminology, a mechanization, a automation, a degree, a level, a effectiveness, a process, a method, a requirement, a automat, a control, a information.
