Risk assessment is basis to put pipeline integrity management in practice and the acceptable risk level is important criteria to execute risk assessment and constitute maintenance safeguard. So it is very important to establish a rational and practicable acceptable criterion and present a specific acceptable risk level. It is just for this need that the present paper gave a review of all the available research around the acceptable risk level and analyzed various domestic and overseas standards and documentation concerning how to define the acceptable risk criteria. As a result, a criterion suitable for oil and gas pipeline was presented and recommended acceptable risk level was gave.

Potential Risks

Due to the sensitivity and vital and undeniable role of gas energy in the energy basket of the country, especially in economy, evaluation of risk assessment studies on the designing and exploiting of this massive and extensive industry including oil and gas pipelines seems to be very necessary. Generally, risk assessment is process of the determining the risk quantity and quality by analyzing potential risks in the project which will be done by taking into account the sensitivity or vulnerability of the surrounding environment. kent Muhlbauer’s method based on relative scoring of parameters that are involved in risks creation deals with the risk assessment. In order to establishment this system for risk assessment of statistical data collection, due to the failure of Iranian oil and gas pipelines, experts and scholars’ experiences as a field project (South Pars gas condensate export pipeline) were collected. According to the existing conditions and availability of information sources in the Iranian oil and gas industry, finally, these data as safety risk assessment criteria of pipelines were processed in a graph and scoring was conducted based on the relative weighting of risk starter elements in the pipeline. according to the obtained scores and the relative risk of different areas of pipeline by considering km scale of areas, it was identified that 16% of the total pipeline had very high risk level, 34% of the total pipeline had high risk level, 34% of the total pipeline had medium risk level and 16% of the pipeline had low risk level.

Aim at gob in loess gully region is the only ways of West—East oil and gas pipeline, the risk assessment on oil and gas pipeline through gob is solve operation of pipelines, and prevent the occurrence of major disasters and urgently need to study and solve major problems. It combines with integral method to further risk assessment on oil and gas pipelines across god based on the results mining subsidence hazard study in loess gully region. The method has proved that has some guidance on risk assessment of oil and gas pipelines through the loess gully region, and it is for further study on overlying gob pipeline movement and deformation to lay the theoretical basis.

Abstract When the operation benefit of an oil and gas pipeline is not enough to cover its operation cost, and the pipeline is no alternative use, seriously damaged, aged or the operation risk exceeds the acceptable range, it is bound to cause serious safety and environmental hazards along the pipeline, especially for the over age pipeline in service, therefore its scientific abandonment and reasonable disposal is particularly important and urgent. Focused on the methods for judging abandonment, retirement modes, cleaning and environmental management of oil and gas pipelines, the characteristics of existing methods for predicting the remaining life of the pipelines and their application in abandonment and disposal are compared and analyzed, and the basis and adaptability of oil and gas pipelines retirement are illuminated. According to the actual situation and environment of the discarded pipelines, the selection basis and applicable conditions of the pipeline and facility disposal methods such as demolition, in-situ shelving and their combination are expounded. It is found that North America has rich experience and mature technology in oil and gas pipeline abandonment and disposal, but many countries, including China, seriously lack scientific and systematic evaluation standards, practical experience, related theoretical and technical investigations. This study has important reference and practical significance for promoting the development of abandonment and disposal technology of an aging oil and gas pipeline, and ensuring the personal safety and ecological environmental protection along the abandoned pipeline. This paper presents the status quo of over age service and abandonment decision-making of oil and gas pipelines in the world, draws lessons from the experience of safety and environmental protection disposal of the global abandoned pipelines, and puts forward the principle and method of abandonment judgment and scientific disposal of the aging pipelines based on residual life evaluation. This method has sufficient basis, strong adaptability and wide application.

For long distance oil and gas pipeline system has the characteristics of high accident rate tending to happen in personnel job activity, this paper expounds the necessity and application steps of HAZOP (Hazard and Operability Analysis) analysis for long-distance pipeline system key operation procedure (SOP). The HAZAOP analysis of deviation, causes of deviation, consequences, existing control measures and recommending measures, make the key operating procedure safer, and also contributes to the improvement of the oil and gas pipeline system safety and fitness between operating procedures and hardware facilities. The results of application examples show that HAZOP is able to identify key operating procedure loopholes, helps enterprises optimize key operating procedures, improves the hardware facilities, and has an important role to improve the security of the key operation of oil and gas pipelines.

Pipelines are regarded as one of the most practical and economical modes for transporting dangerous and combustible substances, such as oil and gas. However, the use of historical failure data in qualitative risk assessment of oil and gas pipelines is unusual due to lack of data or incomplete information. The pipeline incident database (PID) provides valuable information for researchers to identify potential threats of oil and gas pipeline systems, and catty out effective risk assessment. In this study, pipeline failure statistics such as pipeline classifications, incident definitions, failure causes and failure frequencies from the United States, Canada, Europe and United Kingdom are compared. Failure frequency of oil and gas pipelines for different kinds of primary failure causes are estimated from the statistical analysis of the mileage, pipe-related incident, and failure cause data collected by each PID. Although above-mentioned databases are established by pipeline operators in developed countries, the statistical analyses of incidents on oil and gas pipelines based on comparing different pipeline incident databases can benefit the quantitative risk assessment of pipeline systems also in some developing countries where pipeline incident database haven’t been established.

During the construction of oil and gas pipelines, a complex of engineering and geodetic works is necessary to ensure the geometric parameters of the designed routes during their laying. Therefore, the development of new methods for performing engineering and geodetic works for tracing linear structures using modern instruments is an urgent task. The purpose of this research is to analyze the modern methodology for the implementation of engineering and geodetic works for surveying and construction of the gas pipeline. The object of surveying is the route of the main gas pipeline «Aikhal-Udachny». The approbation of the methodology for performing engineering and geodetic works surveying for the «Aikhal-Udachny» gas pipeline was carried out and an analysis of the results was given.
