Risk-oriented Reliability Management Based on Digital Technologies and AI Systems COMPACS

Print
Technogenic safety is a key component of ensuring a refinery or petrochemical company’s profitability. In ensuring a high level of technogenic safety it is crucial to put the focus on machinery reliability control. Risk-oriented reliability management is currently the most demanded approach which is rapidly spreading across the oil-and-gas industry. A high level of safety, reliability, and operational efficiency for all 40 years has been the main concern of the managers and specialists of TOO Pavlodar Oil Chemistry Refinery – the leader of the Kazakhstan refinery industry. That is why the strategy of increasing safety and operational efficiency of productions based on the management of technogenic risks initiated by KazMunayGas was warmly supported by the management and staff of the Pavlodar Oil Chemistry Refinery.

“Big Data” Technologies in Real-Time Health Monitoring Systems

Print

Production today is impossible to imagine without systems for machinery condition monitoring.

Constant increasing level of production automation results in higher number of operating machines and facilities, which, consequently, increases the cost for their maintenance and risk of accidents due to failure.  The most efficient way to reduce the operational costs is to apply a modern technology of resource-saving operation of machinery based on stationary real-time condition monitoring systems.

The papers [1,2] present the most common ways of increasing efficiency of monitoring systems when introduced to production facilities:

- implementation of real-time monitoring systems providing constant control of the most critical machinery;

- implementation of the systems at every stage of their operational life-cycle  (acceptance test, operation, maintenance);

- implementation of comprehensive systems providing monitoring of various types of equipment(such as rotating machinery or static equipment) using a single software-and-hardware platform;

- integration of systems into a single diagnostic network of the enterprise providing information on machinery condition to all interested services.

The real-time application of the “big data” technologies in the equipment technical state monitoring systems allows to increase the efficiency of these systems implementation at modern technological complexes.

Some Problems of Vibration-based Health Monitoring

Print

Integration of the Russian scientific and technological achievements with similar foreign developments caused a conflict of interest and misunderstanding, particularly, in the machinery condition monitoring, diagnostics and health monitoring. The conflict of interest is primarily associated with the commercial interest of certain firms and companies aimed at selling their products and the related intentional and unintentional misconception in the machinery diagnostics. The misunderstanding relates to the lag of foreign countries in some fields of science and technology, specifically, in machinery vibroacoustic diagnostics and health monitoring.

The purpose of the paper is to present the basic terminology of diagnostics, monitoring and vibroacoustics and its application to the real engineering solutions.

The terminology is suggested by guidelines and regulations, reference, scientific and educational materials, including the researches carried out by the authors.

The analysis of the terminology used in Russia and abroad revealed the differing interpretations in solving engineering problems of the machinery condition monitoring, diagnostics, and health monitoring. In particular, the term “condition monitoring” shall be understood as monitoring of state parameters without diagnostics.

It is shown that the vibroacoustic signal is a random process, and the vibroacoustic diagnostics requires analysis of its stochastic characteristics. For this reason, it is necessary to measure vibration acceleration, velocity and displacement, since the stochastic characteristics of these vibroacoustic oscillation parameters are statistically independent.

The studies performed brought us to the conclusion that the real-time health monitoring systems should provide real-time machinery diagnostics at such time intervals, during which the machinery state of health cannot change from normal to limit. In order to minimize the failure missing risk and ensure reliable diagnostics based-on the vibroacoustic signal parameters, one should measure the vibration acceleration, velocity and displacement with an accuracy of few percent over the frequency range of at least 3000 Hz.

Generic structural model of machinery vibroacoustic signal

Print
The paper deals with the challenges of the machinery vibroacoustic signal modeling. The purpose of this paper is to form a phenomenological model for the structure of vibroacoustic oscillations and signals appeared in case of malfunctions and defects. It presents particular structural models for vibroacoustic signals of some reciprocating machine malfunctions. Mathematical description of the vibroacoustic signal reveals the informative parameters of the malfunction diagnostic signs. The model enables us to define in detail the informative vibroacoustic signal parameters. The model also allows us to select the diagnostic signs of the given malfunctions and defects in certain machine parts and components. At the same time, it is considered that the signal is received in certain points on the machine taking into account the excitation sources, conditioning channel and propagation of the vibroacoustic oscillations. The model has been constructed considering the presence and interaction of the three main sources of excitation of the asset vibroacoustic oscillations, which are identified by the types of excited oscillations. It is assumed that there are damped natural, undamped induced, random broadband and narrowband vibrations. The parameters of the vibroacoustic signal structural model also take into account the properties of converting the vibroacoustic oscillation to the vibroacoustic signal by means of a piezoelectric sensor. The model shows that the vibroacoustic signal has not only the components from each source, but their mutually modulated components. We developed partial models for mechanisms of structuring the vibroacoustic signal appeared in case of malfunctions and defects in rotating parts and couplings, machine shaft and drive shaft misalignment, increased clearances and other defects and failures of the rotating and reciprocating parts and components. The proposed phenomenological structural models of the vibroacoustic signals appeared in case of malfunctions of reciprocating machines show that for the diagnostic purposes it is necessary to analyze vibroacoustic signals either in the time domain according to the cyclogram of the reciprocating machine operation or in the envelope spectrum at characteristic frequencies or the noise component. In the event of defects and malfunctions in the centrifugal rotating parts and components, there are excited the vibroacoustic signals, which are advisable to analyze in the direct spectrum or in the spectrum of the noise component envelope. The proposed models enable us to select and form scientifically grounded systems of the machine failure diagnostic signs.

Condition monitoring and diagnostics of drive isolation in rotating machinery of petrochemical facilities by partial discharge method

Print

Condition monitoring and diagnostics of rotating machines, such as pumps, compressors, fans is the most efficient policy to ensure safety and good performance of petrochemical productions. The most common type of drives in rotating machines is electric motors, mostly, induction ones. Despite their high reliability level they also require condition control for both mechanical and electrical parts, because a fault of a drive’s electric motor may lead to an emergency shutdown of the unit. When the controlled machinery is located in hazardous areas, it means that there are special conditions for diagnostic methods and means to be applied. At the same time, using remote diagnostic methods often helps to avoid such restrictions. One of the efficient control methods for isolation condition – including isolation of stators in induction motors is a partial discharge method. The authors suggest their own method of the remote method practice outside the hazardous areas. The data collected in the course of the research show that the remote monitoring of partial discharge parameters is an efficient way of diagnostics of any destructive elements in isolation and monitoring over their development. Further research done by the authors will allow defining and improving the algorithms used for automatic diagnostics of rotating machinery drive isolation.

Safe resource-saving operation, strategy of increasing technogenic safety and operational efficiency of Gazpromneft-Moscow Refinery

Print

Technogenic safety is a foundation of the efficient operation of refineries and petrochemical plants. Larger and more complex hazardous productions of refineries make it vital to increase the reliability and safety along with operational efficiency of productions. Given the maturity of the industry and market conditions, the struggle for margins and product improvement are the main priorities of refineries of such leading companies in the industry as PAO Gazpromneft. That is why the strategy of boosting operational efficiency by increasing energy performance and operational readiness, and reduction of production losses takes a special place among the strategic priorities of PAO Gazpromneft. Today the company is implementing several big projects on building a single digital platform for managing the efficiency of the value chain based on the analysis of process-related data coming from the APCS of its subsidiaries, including the introduction of condition monitoring systems. One of the main tasks aimed at increasing safety and reliability is early detection, monitoring of development, and timely elimination of malfunctions and defects of machinery operating simultaneously at production facilities with a maximum potential residual life.

Condition Monitoring of Drive Insulation in Machinery at Petrochemical Facilities Based on Partial Discharge Method

Print

Currently, asynchronous electric drives are the most common for machinery at petrochemical facilities. To ensure their safe and steady operation it is required to perform monitoring and diagnostics of their condition, and condition of their insulation. In this case, it is advisable to monitor the condition of the power supply circuits as a whole, since the failure of the cable line (CL) or the supply cell will also entail a shutdown of the machinery unit. The authors consider it obvious that such issues are highly important.Currently, asynchronous electric drives are the most common for machinery at petrochemical facilities.

Improved engineering methods of a rotor’s bolt connection state evaluation using multiple-factor analysis

Print

Operation of a turbine unit causes mechano-caloric processes deteriorating state of shafting parts which increases the risk of accidents and emergencies.  Common types of accidents in the power industry in Russia and abroad are the ones related to the deterioration of rotors of a generator and exciter, including the one happening twice in 2013–2014 when there were partial and full deteriorations of half-coupling bolts of the exciter’s armature of a 1000 MW turbine unit. In 2014–2015 several 250 MW turbines bolt connecting high and medium pressure rotors deteriorated soon after the assembly. It should be noted, that some parts can work in similar operating conditions 5-10 years or more, while others degrade in a few months. This is also true for half-coupling bolts. Such a wide range in the wear-off is due to two crucial factors: a)variations of material properties may be caused by a 100% variation of operational characteristics; b) variations of technical deviations due to human factors during assembly may decrease operation life substantially.
