At present, much attention is paid to the training of specialists who operate at responsible and hazardous industries, using various types of benches and simulators. A special place among them is occupied by three-dimensional computer simulators, which are characterized by low cost and sufficient quality of training. The paper presents an approach to developing an integrated control system for computer simulators; its functional chart is proposed. In this work, the problem of modeling complex technical systems taking into account the criteria of complete and realistic modeling and performance is specially noted. There is also an approach to constructing simulators with variable technical object models depending on the target and with a given level of detail. The results of the work were tested in the development of simulators of electrical equipment.

The article presents an approach to the use of artificial intelligence methods in the development of imitation professional simulators. The analysis of the use of artificial intelligence tools for the development of 3D applications is carried out, typical components and their functions are considered, the drawbacks that limit the use of these methods in professional simulators are revealed. The proposed approach is based on adapting these standard tools and supplementing them with functional-logical models that perform control functions. As an example, the implementation of the approach in the Unity cross-platform development environment is proposed. The results of the work have been tested in the development of simulators in the field of labor protection.

The paper considers a technique for analyzing the strength and buoyancy of block pontoons for vertical cylindrical tanks used for storing liquid oil products. A model is proposed for performing calculations by the finite element method of a pontoon for buoyancy and strength, taking into account the action of pushing forces. The results of calculations on strength and buoyancy of an aluminum pontoon with foam-urethane filling BPA5000 are presented. It has been established that BPA5000 pontoons have sufficient strength and buoyancy, as regulated by GOST 31385-2016.
