OVERVIEW OF SOFTWARE PRODUCTS ALLOWING TO AUTOMATE PROCEDURES FOR PRODUCTION CONTROL AT HAZARDOUS PRODUCTION FACILITIES OF OIL AND GAS PRODUCTION FACILITIES
This article discusses a brief overview of software products and cloud services that allow automating procedures related to the organization and implementation of industrial control over compliance with industrial safety requirements at hazardous production facilities of oil and gas production facilities. Requirements for the organization and conduct of industrial control are defined by the law on industrial safety .
The analysis of software products and cloud services is performed from the point of view of automation of accounting, planning, monitoring of production safety in accordance with the requirements of the legislation of the Russian Federation, as well as taking into account the specifics of the oil and gas producing industries HPF operated and the conditions of their operation. Software products are considered, information about which is available in open sources. Some of the software products are patent developments of scientific institutes. The review of the software products presented in the Russian market is given, their strengths and weaknesses are highlighted. The elements of the production control system and the controls of the production control system are analyzed, and the relationship between these concepts is defined. In the course of the comparative analysis, the advantages and disadvantages of the automation tools used in the management of industrial safety were revealed, as well as the functions currently not implemented in existing programs, allowing to measure the level of industrial safety, improve the effectiveness of the organization of industrial control, ensure transparency of industrial safety processes and information support for decision-making based on facts, including assessing the actual situation industrial safety and identified violations of industrial safety requirements.
At present, special attention is paid to the issues of industrial safety in oil refineries. This is due to the growing number of accidents in recent years. The most likely are the emergency situations associated with the process pipelines depressurization due to their corrosive wear, the normal process conditions violations, planned preventive maintenance insufficient quality, etc. Process units’ incomplete loading, caused by a change in the raw materials consumption structure at enterprises, leads to a change in the equipment loading regimes and the increase in its stops. To a greater extent, this refers to the process pipelines linking the reactor equipment, which has a no stationary change in the stress state. In this connection, it became necessary to develop a method for determining the process piping movement when the reactor axis misaligns from the vertical.
The process piping deformation calculating results verification in the reactor axis misalignment from the vertical obtained in the SOLID WORKS software package and their comparison with the results of the reactor prototype mock-up with process piping were performed in this work. Ultimately, this allows creating a unified approach to the various factors influence study on the reactor pipeline systems, which is an important task that contributes to improving reliability and trouble-free operation. The estimation of deformation displacement piping axis deviation from the vertical reactor standard, numerical and observational methods, the comparative analysis of the results obtained.
To increase the level of qualification and training on industrial safety at the enterprises operating hazardous production facilities in the framework of the functioning system of industrial safety management provides the mandatory training and testing of knowledge of employees, as well as periodic training actions in emergency situations. The result of this study is to assess the level of compliance of professional competences of workers to the industrial safety requirements. The formation of professional competence is significantly affected by the level of development of individual professionally important qualities of employees. To improve the efficiency of compulsory education in the field of industrial safety automated systems for evaluation of professionally important qualities of workers of the main professions were developed and implemented, as well as operational staff, determine not only the willingness of staff to act in emergency situations, but also to carry out works of heightened danger. The development of these automated systems included the following main stages: study of the productive activities of employees; expert assessment of the significance of the qualities necessary for the successful management of emergency operations and hazardous work; determination of information content of the standardized tests for the assessment of the identified characteristics; the establishment of local standards for each test and the integral criterion to assess the readiness of the worker to actions on localization and liquidation of consequences of accidents and to carry out works of heightened danger. The use of these automated systems will allow, on the one hand, to reduce the likelihood of accidents by increasing the effectiveness of the procedure of mandatory training and testing of knowledge of requirements of industrial safety workers of basic trades and on the other hand, to reduce the extent of the damage in the implementation of accidents due to preparedness of the operational staff of the hazardous production facilities for action localization.
APPLICATION OF FINITE ELEMENT ANALYSIS FOR SOLVING ISSUES OF FORECASTING BEHAVIOR OF VERTICAL VESSELS WITH PROCESS PIPING IN EMERGENCY SITUATIONS
Second half of the twentieth century became the time of active development of such applied academic discipline as industrial safety. First of all it was connected with the industrial-production growth, increase of its concentration, complication of technologies, application of wide range of new types of substances taking part in processing procedures and so on. All of this resulted in a situation where occurring technogenic accidents possess increasingly cata.
Accidents at the enterprises of oil and gas industry usually result in high vol-ume emissions of explosion and fire hazardous substances which generate fuel-air mixture clouds, petroleum products spills and as a result – fires, explosions, failure of vertical vessels and whole installations.
Nowadays issues related to practical calculation of accidents consequences, taking into account dynamic factors affecting strength and stability of structures under the influence of external factors, including explosion, are still poorly covered.
Performance of precise numerical experiment can significantly improve safety of the facility and save time and resources, required for carrying out live experiments, for designing new facilities, moreover it can reduce accident risk of existing facilities.
The article contains development with the application of numerical methods of the model of dynamic behavior of vertical vessel with process piping under the influence of shockwave effect in full three meters positioning and taking into account multifactorial loading and detalization of object geometry. Typical changes of plastic strains distribution in different elements of the considered system, depending on the direction of shockwave effect, were analytically obtained.
At present, one of the main industrial components of the country is the oil and gas industry. Oil production, oil refining, oil transportation – all links of the oil shoulder are an integral part of the world hydrocarbon space.
A feature of the oil industry personnel labor is the impact on workers of dangerous and harmful factors that threaten health and life. The deterioration of the health of the able-bodied population, the reduction in the period of active working capacity, the increase in the number of diseases, disability and even the early death rate caused by professional activity is one of the main problems of the Russian Federation. That is why the tasks of the state as a whole and of any oil industry enterprise in particular are to maintain professional health and longevity through developing technologies and reducing morbidity and injury.
Statistical information on accidents and injuries in Russian industry is presented. The structure and dynamics of occupational morbidity in the oil and gas industry are shown. The main methods of analyzing the danger of occupational diseases in oil refineries are considered.
The method of integrated assessment of the harm index using is proposed. It is shown that its implementation in combination with modern monitoring technologies will allow to develop and implement a professional risk management system, to justify a rational set of measures to improve working conditions at oil refineries.
