Complete Inspection

In this paper a process framework was constructed for the inspection and assessment of urban gas pipeline. Take a certain gas pipeline network as an example, work directory for complete inspection was established as well as models for risk assessment. Feasible and effective rectification measures could be taken according to the relative importance of the results of the inspection and assessment. Some work in this paper could be adopted for the inspection and assessment of urban gas pipeline.

Objective: Identifying an accurate quantitative risk assessment. FEC (Fuel and Energy Complex) plants are a high-risk area as they may cause manmade disasters, various accidents, pose a threat to human life and environment. In addition, the Russian energy industry is noted for its high complexity and social responsibility. Its specific feature is that it is not always possible to make an accurate quantitative risk assessment reasonably in advance and its degree determination methods are not well enough developed. In view of the above, there are some difficulties in minimizing the risks and estimating risk management costs. There has been a recent trend in improved current legislation on industrial safety and Rostechnadzor (Federal Environmental, Industrial and Nuclear Supervision Service of Russia) oversight and supervision activity practice toward implementing a risk-based approach using the risk analysis methods. It allows optimizing the methods and frequency of inspections made by regulatory bodies depending on the risk level of facilities supervised. Methods: The (accident) risk analysis is performed as a certain scientific justification set forth using qualitative and quantitative analysis of a potential accident likelihood, consequences of its occurrence, and identification of the weakest points in the engineering system or complex. Using fault tree analysis, this article identifies hazards and assesses the high-pressure gas pipeline loss of containment risk, one of the events possible for an energy provider in operation. Results: Based on the risk analysis, there has been a proposal to replace gland seal valves with bellows seal valves noted for their optimum relationship between the unit reliability, cost and sophistication level. In case the facilities with gland seal valves remain in operation, improved production process monitoring is recommended using gas leak detectors and automatic interlocking devices. Practical importance: The measures proposed will allow minimizing the gas pipeline loss of containment risk.

Pipeline Failures

Gas transmission pipelines mainly transport flammable fluids across the length and breadth of the country especially in the Niger Delta region of Nigeria. The associated risk to both the individuals’ encroaching and inhabiting areas along the right-of-way (ROW) and the society at large cannot be underestimated. Thus safety concerns considering the individual and societal risk of pipeline failures has become important. This paper attempts to develop a model for both individual and societal risk assessment for a 12km length natural gas transmission pipeline in Utekon community (commencing from the Benin-Auchi through Uhuwmunode Osina town and terminating in the Benin-Agbor axis) in Edo State using the Chemical Process Quantitative Risk Analysis Method (CPQRA). The CPQRA is used because it examines the hazard zones within a pipeline ROW and the number of persons that would be affected by fire/explosion. Finally, field data was used in this study to validate the model which can be applied to any natural gas pipeline risk assessment scenario.

Gas Network

The paper presents a complete risk assessment system of urban natural gas network from seven modules. Pipeline hazard scenarios are analyzed and the reasons for seven modules risk assessment system model are presented. Based on objective data of various pipeline sections, the assessment system also allows sections of pipeline to be ranked into a risk hierarchy by using advanced scientific mathematical treatment methods. The system is displayed in geographic information system (GIS) platform, in order to implement data resource sharing and visualization of assessment results. Therefore, the dynamic and safety management of gas pipeline network is achieved and the safe and reliable operation of urban gas pipeline network can be ensured. An application based on a real case study was undertaken so that the effectiveness of the assessment system could be verified.
