Embodiment Construction

[0030] Take the present invention to be implemented as an example in Guangzhou by the Guangzhou City Gas Company below for further description.

[0031] Implement the following steps:

[0032] (1) Segment the gas pipeline;

[0033] (2) Classify the parameters that cause pipeline risk, and assign weights according to the influence of each parameter on gas pipeline risk;

[0034] (3) Using the parameters and their weights in step (2), carry out risk assessment for each factor of the pipeline, and calculate the index sum;

[0035] (4) Calculate the gas pipeline leakage influence coefficient according to the danger of the transport medium and the size of the influence surface;

[0036] (5) Comprehensively calculate the relative risk value according to the index of step (3) and the leakage influence coefficient of step (4);

[0037] (6) Analyze the relative risk value obtained in step (5), and draw a risk conclusion.

[0038] Among the four factors of pipeline segmentation in s...

Abstract

The invention provides a fuel gas pipeline risk assessment method based on Mu model. The method comprises the following steps: (1) dividing a fuel gas pipeline into sections; (2) classifying parameters causing pipeline risk and distributing weightings according to the degree of impact of each parameter on the pipeline risk; (3) through the parameters and weightings of the step (2), carrying out risk assessment of each factor for the pipeline and working out an exponential sum; (4) calculating the fuel gas pipeline leakage influence coefficient according to the risk and influence surface of a conveyance medium; (5) working out a relative risk value integrally according to the exponential sum of the step (3) and the leakage influence coefficient of the step (4);(6) analyzing the relative risk value obtained in the step (5) to obtain a risk conclusion. The invention adjusts the factor weightings of the Mu model risk assessment and is provided with the fuel gas leakage influence coefficient to be computed, thereby bringing about more adaptability and more accurate and reliable assessment results.

Description

technical field [0001] The invention belongs to the technical field of risk management of gas pipelines, in particular to a risk assessment method for gas pipelines based on the M Moser model. technical background [0002] With the continuous laying of oil and natural gas pipelines, the risk management of oil and gas pipelines has attracted worldwide attention. With the continuous development of the computer software industry, it has become a trend to carry out pipeline risk management in the form of computer software. Foreign countries started earlier in pipeline risk assessment software, and already have many powerful assessment software; China has only developed software in this area in recent years, and there have been some products so far, but these products, except M Moser software , there is no one for the risk assessment of urban gas pipelines. There is a module in M ​​Moser software specifically for urban gas pipelines. However, due to some particularities in the d...
