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.
THE ANALYSIS OF DANGERS, ASSESSMENT OF RISK OF ACCIDENTS ON HAZARDOUS PRODUCTION FACILITY AND THE RECOMMENDATION ABOUT THE CHOICE OF METHODS OF THE ANALYSIS OF RISK
High level of threat of emergency situations of natural and technogenic nature and tendency of growth of quantity and scales of consequences of emergency situations require to expect future threats, risks and dangers, to apply methods of their forecast and prevention.
In article the main questions connected with the analysis of dangers, a risk assessment are considered. It is shown that a main objective of risk analysis of accidents is establishment of degree of emergency danger of hazardous production facilities and (or) its components for the advance prevention of threats of damnification of life, to human health, harm to animals, plants, environment, safety of the state, property of physical persons and legal entities, the state-owned or municipal property, threats of emergence of accidents and (or) emergency situations of technogenic nature, development, planned implementation and timely adjustment of reasonable recommendations about decrease in risk of accidents
Methodical the basics on carrying out the analysis of dangers and risk assessments of accidents on hazardous production facilities are covered. Methods of risk analysis of accidents are described and analysed. Recommendations about the choice of methods for different types of activities and the main stages of lifecycle of dangerous production process are provided.
The quantitative risk assessment of accidents is characterized by calculation of several indicators of risk and can also include one or several above-mentioned methods (or to use their results) and allows to estimate and compare various dangers and hazardous production facilities on single indicators and is most effective.
THE IMPROVEMENT OF SAFETY LEVEL AT HAZARDOUS PRODUCTION FACILITIES, OPERATING EQUIPMENT, WORKING UNDER OVERPRESSURE
Exploitation of oil and gas equipment, working under excessive pressure is factor leading to the manifestation of emergency situations and accordingly serious consequences on dangerous industrial objects.
Hazards of the equipment working under overpressure in the operation were studied. An analysis of accidents and injury of considered equipment was conducted. The need for improvement and introduction of more advanced technologies training of personnel for the purpose of increase of level of industrial safety and working conditions in the workplace is shown. The safety of hazardous production facilities, is a complex of interrelated organizational and technical measures aimed at trouble-free work of the enterprise. Safety of hazardous facilities is not only direct compliance with all mandatory rules, it is, above all, stable operation of the main production with the use of properly functioning equipment, carrying out timely and quality repairs, and if necessary upgrades or replacement.
The erroneous actions of the personnel in normal and especially abnormal situations that are the result of incorrect assessment of potential hazards, as well as intentionally or unconsciously ignoring signals about violations of technological processes.
Statistics show that such errors lead to a 20-30% failure rate of the equipment operating under excess pressure. In General, industrial enterprises 80-90% of accidents are caused by the fault of the workers themselves.
The reliability of functioning of technical devices subject to pressure is determined not only by strength and resistance of their structural elements, but also to some extent dependent on the reliability of knowledge and professional skills of the personnel, continuously serving the whole system of hazardous production facilities technical devices including.
MODELING OF SCENARIOS OF DEVELOPMENT OF EMERGENCIES FOR NON-STATIONARY HAZARDOUS PRODUCTION FACILITIES OF AN OIL AND GAS COMPLEX
Results of the analysis and researches of not stationarity of technological processes and processing equipment are given in article and need of their account at design and safe operation of the hazardous production facilities (HPF) of an oil and gas complex is shown.
Research and the analysis of results of inspection of conditions of emergence and development of emergencies are carried out taking into account the analysis of not stationarity of conditions of emergence and development of emergencies in the main technological modules of the ELOU-AVT installation.
According to inspection the formalized models of “trees of refusals” and “trees of events” taking into account not stationarity of risks for head OPO were constructed.
The analysis of development of scenarios of accidents by means of the formalized models of “trees of refusals” and “trees of events” is a component of system of the analysis and management of minimization of the risk allowing to consider influence of the striking factors, to estimate zones of defeat and to develop organizational and technical actions for early prevention of emergencies at a design stage and operation.
Algorithmic providing an assessment of a relative indicator of danger of the processing equipment allowing to estimate total potential fire danger, potential of explosion and reliability of the equipment taking into account not stationarity of operation of OPO is developed.
The assessment of degree of danger of OPO taking into account their not stationarity allows to develop the control system of minimization of technical risk providing safe operation of processing equipment on this basis.
THE IMPACT OF ELECTRIC POWER QUALITY PARAMETERS ON THE INDUSTRIAL SAFETY AT HAZARDOUS PRODUCTION FACILITIES
The problem of the electric power quality impact on the work of the electric power receivers which are involved in technological processes on hazardous production facilities has been considered in the article.
The main electric power receivers on hazardous production facilities are: electric thermal plants, pumps’ electric engines, fans, conveyors, etc., interior and exterior illumination, relay protection and production processes’ automation.
The devices which use electric power work properly in the cases if the voltage and the frequency are close to their nominal values and if the interruptions in the electric power supply are not so frequent.
In this case the electric power supplied is considered to be of a high quality. Changing the consumer plants’ parameters and the appearance of new devices makes not only to seek for the obtained quality maintenance but to constantly improve it as well.
The electric power quality depends on dozens of factors. To these indices belong such characteristics as frequency, voltage, sinusoidal curves of voltage and current, currents’ unbalance between phases and many others. All these characteristics influence the equipment performance quality and stability involved in technological processes on hazardous production facilities.
The article deals with the consequences to which an incorrect use of the low quality electric power by some receivers may lead and a conclusion is made that for electric power quality parameters’ maintenance the efforts of the electric power grid company are necessary as well as those of the electric power consumer organization.
Monitoring and maintaining the electric power quality parameters while operating at a hazardous production facility allows to significantly reduce the possibility of the equipment failure, a false automatics operation, an accident occurrence, i.e. makes for the industrial safety at hazardous production facilities
