Application Of The Safety Assessment In The Construction And Management For West-East Gas Project

Long-distance natural gas pipeline safety and reliability of the rapid development makes it increasingly prominent issue, increase the predictive power of the accident is to achieve safe and efficient gas transport capacity of the key. Gas Pipeline Safety Assessment Research Project is to improve the gas transmission engineering design, construction, operation and other aspects of reliability, increase accidents and hidden the predictive ability, to minimize accidents caused by economic losses, personnel casualties and damage to environment.This article discusses the safety evaluation of natural gas pipeline in the importance of safety engineering to introduce a safety assessment of basic knowledge and theory, summed up the domestic and international pipeline safety evaluation technology of the status quo and for the characteristics of long distance gas pipeline project from a different angle Select the Pipeline Risk Assessment Method (EST), hazard and operability study(HAZOP), job safety analysis (JSA) for safety evaluation applied research.To West-East Gas Project as an example, through the pipeline failure factors and the type of statistical analysis of the accident, according to West-East Gas Project delivery media properties, such as the inherent risk characteristics of hazards analysis; and the establishment of pipeline risk models to develop the corresponding evaluation index system to determine the weight of various factors, the value of failure and evaluation of scores, calculated by the evaluation of pipe sections relative risk value, intuitive display a full range of the risk of West-East Gas Pipeline .West-East gas pipeline project through a typical station yard, valve chambers, gas storage system HAZOP analysis process to identify the original process system design deficiencies and defects, increased the reliability of gas transmission engineering design and construct. Risk for a typical operation, application of operational safety analysis (JSA) to fully recognize the risks involved in operations and to develop control measures to improve the West-East Gas Project safety management and safe operation level.
