Study On Gas Project Construction Management Of Tianjin R Corporation

With the rapid development of China's urbanization process,as to the domestic and international's attention, urban gas pipeline is growing popularity and its scale is gradually increasing. Meanwhile , as we all known, the frequent gas pipeline .accidents associated with safety have become a social and public question. The safety problems of city gas projects have the character of complexity, wide-ranging and systemization. Safety management is not just confined to the internal gas enterprises, but opens to the whole society. Therefore, the safety management of gas corporations has great importance on the steady of society and the safety of people lives. How to make sure the end-users' safe applications and strengthen security of the whole gas system operation, has been a problem concerned by professionals. At the same time, it's important to the property and society stability.The main contents of this article is to analyze the prone problems of gas projects and find out the existent situation of safety production management of city gas corporations in our country, and then discusses the importance of safety management to city gas corporations etc. Based on the accident rescue system, we makes use of the responsibility matrix method to let the emergency department or emergency rescue person understand the responsibilities during resources scheduling, to know Which part undertake the support responsibility. So that they can allocate resources rationally during the operation of emergency resources.The first chapter, Introduction section, we discussed article topics about the research background and research significance and did a basic literature review and present the necessary theoretical basis of research needs, and finally Finally, we outlined the main contents of text and technology roadmap.The second chapter, We analyzed the concept of emergency gas works, and discussed emergency management and emergency gas works between. Between them, always hand in hand. We described the characteristics of accidents of gas, gas transmission and distribution system, the environment in which gas pipelines, gas and gas pipeline risk factors inherent in, gas and gas pipeline management, risk factors etc, and analyzed the relationship between them and security risks.In chapters III and IV, we discussed the buried gas pipeline leak accidents, development and evolution mechanism, and focused on the city gas pipeline construction process management. Meanwhile, based on the success of integrity management of the oil and gas pipelines, the integrity management of city gas pipeline is put forward, which is the new higher rank security management model than the safety management and the risk management. It is to ensure that city gas pipeline running economically and in security as the core goal, and to make pipeline management standardized, procedural, scientization and standardization through carrying out a variety of potential factors comprehensive, integrated management. Pipeline integrity management has become the most recognized security management model. Currently, the pipeline integrity management has become a hot field of pipeline engineering. Through the pipeline integrity management, we not only can greatly reduce the incidence of pipeline accidents, and also avoid unnecessary and unplanned repair or replacement pipes, which will bring a huge economic and social benefit. Meanwhile, we analyzed the risk assessment model of city gas pipeline network. With the pipeline index risk assessment method, the failure probability and consequence of the evaluated system are received. After the risk degree is evaluated, the pipeline risk control and decision-making system is established. We analyzed the essential characteristics of the risk. This shows that the city gas pipeline network and application systems of risk management has many practical significance, such as raising the level of management decision-making and optimize the cost of risk relationship, in a timely manner to eliminate risk factors, improve system reliability, integrity and safety, reduce sudden catastrophic events. Through the analysis of urban buried gas pipeline leak incident response resource scheduling factors, we proposed and analyzed the buried city gas pipeline leak emergency resource scheduling. On this basis, we established a buried city gas pipeline leak emergency resource scheduling model. Scheduling model discussed in this chapter is intended to aid the primary objective of the fastest action, and on this basis, we optimized the number of rescue points and quantified the reliability of transport routes. We considered adding the early leakage, duration, consumption of resources required for recovery, at the same time, we take into account the preliminary results appear after the disposal of resource requirements, and established a mathematical model, which begin emergency first time, the minimum number of save points and the reliability up to goal, from weighing options to find the optimal resource scheduling scheme. This chapter used a multi-objective decision method to solve multi-objective optimization problems, and solutions will take into account the shortest and most reliable rescue point at least a compromise combination.In Chapters V, we analyzed the responsibilities of gas pipeline construction management units and pointed out that the construction unit of the gas project investment, quality, schedule should be an indirect means of control, and orderly. Only supervision, construction, quality control and other units check at each level that would further reflect the design drawings to the construction results, and ensure the construction quality has been improved in order to guarantee the people use the security and stability of gas. We studied the gas leakage of buried pipeline emergency resource management. Emergency resource management is a dynamic equilibrium system, including emergency resources reserves, demand, supply and use of four continuous cycle process. Gas Group, in accordance with the characteristics of gas and gas accidents accident rescue experience, developed a gas emergency rescue plans for emergency incidents, including the company level, division level, plant (unit, team) level emergency response plan, and timely to carry out emergency rescue exercise. Gas pipeline emergency rescue team accepted the dispatch room of the branch command of Gas Group, and emergency rescue personnel repair the gas accident in the process according to the following chart, and the simulate rescue exercises on the accident scene. Since the sudden gas leakage and complexity, it may be involved in emergency rescue departments are more prone to tangle as a result of responsibility for the phenomenon, affecting the efficiency of emergency rescue. To avoid this phenomenon, we must first distinguish which of the emergency rescue departments bear the primary responsibility for the rescue workers and department specific tasks undertaken, to make each of the participating emergency services to know exactly what they were going to complete the task, enable better collaboration between departments to ensure adequate emergency response resources to support. Based on the accident and rescue system we use responsibility matrix method to make the emergency department or emergency rescue personnel understand the responsibilities and resources, scheduling, and make sure distinction in the emergency rescue departments in which the primary responsibility for which part of the commitment to support the responsibility. So that we can allocate resources reasonably during the operation of emergency resources.In Chapter VI, I summarize the full text. Through writing this master's thesis, I have learned lot questions that my work needs to be known but they are not very clear. I further understand the operation of gas supply system, gas pipeline and the possible risks of accidents and so on. This experience laid a solid theoretical foundation for my future work.
