The article presents the results of research of orthogonality of the signals of vibration acceleration, vibration velocity and vibration displacement in the course of the defect development by means of numerical simulation of defects and correlation analysis.
Orthogonality of diagnostic features is an important condition that significantly simplifies the process of vibration analysis of the equipment condition. The more independent characteristics form a vector of diagnostic features, the easier to relate it to the vector of the equipment condition.
The dependence of the equipment condition is simplifying if all diagnostic features of a vector are orthogonal.

The analysis of failure level of process equipment (furnaces, columns, machinery, etc.) shows that machine equipment failures make up about 70% of all failures. Thus, the automation of control over equipment operation on the basis of real-time vibration monitoring of the equipment condition is an actual problem.
Automated Control Systems of Safe Resource-saving operation and Maintenance of equipment (ACS SRSM™), which were developed by DYNAMICS Scientific & Production Center (SPC) for vibration analysis and control over safe resource-saving operation on the basis of real-time condition monitoring of equipment, solve the following problems:
vibration analysis and prediction of major malfunctions (> 95-98%) of equipment with early detection, full use of resources and retention of maintainability;
notification to the personnel of urgent immediate actions intended to control the equipment condition;
monitoring of execution of diagnostic instructions of the systems and the personnel actions through network (Internet) engineering;
development of the plans of targeted repairs in accordance with the actual technical condition of equipment;
elimination of design and installation mistakes;
optimization of flow charts and equipment configuration;
keeping the databases of diagnoses, works, replacements and service lives of equipment, reporting at all control levels of the enterprise.

The paper presents the strategy of integrated continuous control of equipment condition that is based on real-time acquisition and analysis of objective instrumental data on actual technical condition of equipment. The data sources are the complexes of acoustic emission monitoring of capacitive equipment (vessels, instruments, pipelines, etc.) and the complexes of condition monitoring of rotating equipment (pumps, compressors, fans, smoke exhausters, etc.) by the parameters of vibration, current and temperature.
This strategy is implemented in the COMPACS® systems for computer monitoring of the machinery condition, which enables complete elimination of sudden failures, increase of safety and cost efficiency of operation of hazardous production facilities and comprehensive solution of a problem of increasing run-to-failure period of equipment provided transition to operation in accordance with the actual technical condition.
Problems associated with wear of basic production assets of hazardous production facilities of chemical, petrochemical and oil refining enterprises and actual condition of process equipment necessitate search, development and implementation of modern advanced technologies for monitoring of the equipment condition and systems for maintenance based on the principles of use of actual resources of safety. Experience of development and maintenance of modern control and diagnosing systems based on the methods of acoustic emission and vibration monitoring enables realization of the basic principles of the strategy of preventing maintenance, safety and resource-saving technologies.

Energy-saving and reduction of power consumption of equipment are vital problems for modern businesses. One of the ways to solve them is equipment operation in conditions ensuring energy-saving.
The analysis of operation of equipment most accepted by the enterprises - pumps, compressors, fans, electric motors - showed that electricity consumption may be reduced by 15-25% by improvement of its technical condition, which requires timely determination of equipment condition and unfavorable operating conditions, informing service and managing personnel in case of degradation of technical condition and violation of operation conditions in order to take urgent measures.
The assigned task is successfully solved by various systems: the COMPACS® system for vibration monitoring and vibration diagnostics, the COMPACS®-micro personal system, vibration diagnostics systems for repair departments integrated into diagnostic network Compacs-Net®. The analysis of sources and reasons for immediate effect after the system implementation permits to affirm that real-time vibration monitoring of equipment complexes enables company profitability on the basis of resource-saving safety.
