ACCOUNTING OF FUNCTIONAL CONDITION OF THE PERSON IN CASE OF THE ADMISSION TO WORKS FOR RISK DECREASE IN WELLS CONSTRUCTION
Statistical data on accident rate on objects of an oil and gas complex confirm a high role of “a human factor” in the causes and escalation of emergencies. Scientific research in the field of influence decrease of a human factor on accident rate is directed as to creation of modern imitating and training systems, improvement of procedures of professional selection, as to assessment of working conditions and a current functional state of the person in a working environment. At risk management in aspect of a human factor the main emphasis is placed on assessment of competences of personnel, their formation and development. Assessment of competences of the candidate – the first thing that the person faces at the device on hazardous production facility. Assessment procedure can be expressed in the form of an interview, passing of testing, an examination during the solution of the offered tasks. At the same time actually there is no assessment of a state in which the examinee is.
Article is devoted to the assessment of influence of a person’s current functional state on risks of emergencies on objects of an oil and gas complex. The hazardous production facility chosen for an experiment is described, assessment procedure is also given. Results of assessment of risk according to which it is possible to draw a conclusion that the reason of development and escalation of 20 % of emergencies on the chosen hazardous production facility of an oil and gas complex is the non-optimal current functional state of personnel of an object, responsible for safe functioning. Carrying out this analysis allows to reveal also the concrete factor of a functional condition of the person having negative effect on indicators of safe functioning of hazardous production facility. Identification of negative factors is a basis for development of methods of psychological ensuring activity of personnel of hazardous production facility and also improvement of procedures of professional selection and the admission to works of the increased danger in an oil and gas complex.
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.
In the structure of the mineral – raw material base of Russian oil is increasing the proportion of hard-to-reserves, which by some estimates is currently about 60% of all open oil reserves of the country . Since the active reserves are produced quickly enough to compensate for this factor must be at the expense of hard-to-stock. That is necessary to increase the volume of drilling and apply new technologies for the production of hard-to-stock. There are many technologies for the production of stranded by increasing injectivity of injection wells and production wells intensification of work. One of the main methods to increase injectivity of injection wells and the intensification of work of oil wells is hydraulic fracturing, for which you want a fairly large amount of equipment and personnel. The method is to increase the existing and creation of new held high cracks in the reservoir for fluid flow to the bottom of the well. Upon stimulation of the well by this method is extended her life and production rate increases. With the development of this method in Russia, frequent accidents, for example, open spouting wells after hydraulic fracturing and resulting in injury and death of workers. The current situation makes it necessary to increase the level of supervision of the operation of hydraulic fracturing and proper operation of the equipment used.
In this article the events that are associated with an increase in safety when developing wells after fracturing operation.
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.
Fire safety at the objects of petrochemical and oil production is a very important part of fire safety. Fires and accidents on objects of oil refining lead to serious consequences for the environment and for the population.
In the country repeatedly carried out reforms that affect the institutional foundations of fire protection, repeatedly changed affiliation, and departmental affiliation. One of the main components of fire protection – contractual Federal fire service of state fire service SBS FPS(contractual) were created in the course of reforming of the object of units of the state fire service in large industrial plants, oil, gas, chemical, metallurgical industry, etc [1-4].
Work on prevention and extinguishing fires in such enterprises requires qualified knowledge, abilities, skills, techniques and technologies in petrochemical industry processes [5-6]. Contractual fire departments are much better equipped with fire equipment, fire and technical equipment than the fire Department, containing at the expense of the Federal budget (again, thanks to the owners of the enterprises). The content of these units (FPS GPS (contractual)) does not cost the state a dime. Besides the Contractual Federal Fire Service go on suppression of fires and liquidation of accidents, emergencies in nearby communities – this should be beneficial to the state!
The aim of this work is to analyze the state of fire protection on objects of oil refining and petrochemistry.
