Research And Practice Of Lean Safety Management In Petrochemical Engineering Project

Under the international situation of increasingly intense energy crisis, to ensure China's energy security, it is an inevitable growing trend for petrochemical industry to enhance production capacity and to extend and expand petrochemical projects. Meanwhile, the petrochemical industry is the third largest high-risk industry, following coal production and firecracker manufacture. In recent years, serious accidents have cropped up incessantly in petrochemical enterprises, which severely threaten national security, environmental protection and people's lives and properties. Therefore, there is an urgent demand for research on safety management theories and innovative methods for petrochemical projects. It undoubtedly is of great practical and theoretical significance in promoting the safety management of the petrochemical industry in China.This dissertation first summarizes the theories, methods, present situation and developing trend of safety management systematically, and then analyzes lifecycle operations and management features of petrochemical projects. It points out that a petrochemical project is a typically complex socio-technical system. Hence, the general principles of security control in the complex socio-technical system should be complied with. Meanwhile, the operational mechanism of the organizational management and the factor of "person" in safety management should also be focused on.On the basis of analysis on current management situations of Chinese petrochemical enterprises, this dissertation points out that it is a new direction of management innovation to implement lean management in petrochemical enterprises. While systematically identifying the organic links between safety and leanness, this dissertation presents the concept of efficient and lean management. Adhering to the basic principles and methods of lean management and using the theory of safety chain management for reference, a model system of lean value chain management is established. In order to create high reliable organizations, an elemental system of management measures is built from three dimensions:the safe production operation subsystem, security control subsystem and safety culture subsystem.Due to the difficulty of knowing-doing transformation in the lean safety management of petrochemical projects, system dynamics theory is employed to construct the system dynamics model of lean safety transform. A simulative analysis was conducted based on the model of a 500 tons/year refinery expansion project in a petrochemical corporation, and the effectiveness of the model was also verified. Further research will be done to evaluate the model parameters psychologically and sociologically.
