Description

Technical Field

[0001] The present invention relates to the technical field of production safety management and risk assessment, and in particular to a covering and non-missing hazard identification method for an oil and gas transportation system. Background Art

[0002] At present, the dangerous and harmful factors in equipment and facilities are based on the failure of components and accessories, which cause equipment and facility failures or accidents. Only then can the damaged components or accessories be found out based on the disassembly results of the equipment and facilities. If we can find the time and type of possible component and accessory failures in advance based on the hierarchical structure given by the equipment and facilities and the failure probability and service life of the components and accessories given by the manufacturer,

[0003] In the case that the evaluation system exists but is not decomposed, the understanding of the system is limited to the equipment, facilities, and devices that can be seen on the surface. The system's vulnerable points, failure points, aging points, vibration points, erosion points, and impact points cannot be detected and monitored. As a result, it is impossible to accurately know in advance the technical status of components and accessories before they may fail and cause the failure of the system, nor is it known what potential hidden dangers these components may involve in mechanical, electrical, electronic, stress, thermal, enabling, sensing, and other aspects.

[0004] Because the structural conditions of the equipment and facilities have not been analyzed and the performance information of the components and accessories has not been thoroughly understood, it is impossible to effectively identify the physical phenomena such as movement, electric shock, hot melting, heat absorption, heat dissipation, magnetic field, pressure, induction, vibration, microwave, friction, radiation, ionization, fluctuation, stress, air pressure, temperature, light sensitivity, potential energy, impact, manufacturing, and freezing that may exist in the equipment and facilities, as well as chemical phenomena such as oxidation, corrosion, reaction, combustion, explosion, synthesis, polymerization, replacement, hydrolysis, cracking, addition, and substitution.

[0005] However, in the actual identification of hazard factors or risks, we often only identify simple phenomena such as defects and appearance changes of these physical and chemical phenomena. We do not investigate how these physical and chemical phenomena produce energy transfer, material exchange, and the generation of new material components, and ignore these physical and chemical processes that should be studied in depth or continued. As a result, a large number of hazard factors are not properly identified, and the manifestations of physical and chemical hazard attributes are not included in the identification, resulting in many omissions in the identification of risks and hidden dangers of many problems, so that some necessary risk prevention and control measures are not identified and prevented. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a covering and non-missing hazard identification method for an oil and gas transmission system. In the case where the evaluation system exists but is not decomposed, the cognition of the system is only the equipment, facilities, and devices that can be seen on the surface, and it is impossible to effectively detect and monitor the system's vulnerable points, failure points, aging points, vibration points, erosion points, and impact points. A covering and non-missing hazard identification method for oil and gas transmission is provided, which can effectively detect and monitor the system's vulnerable points, failure points, aging points, vibration points, erosion points, and impact points, thereby effectively preventing safety hazards.
