Research on the Risk Grading Division of Oil and Gas Pipeline Based onWeb GIS

摘要

The safety management is among the most important management work for oil andrngas pipelines. As an alternative, the risk grading division based on WebGIS is beingrnconsidered to improve safety management. An information management system forrnoil and gas pipeline based on WebGIS has been established using ArcGIS Server asrnthe developing system of WebGIS, SQL Server as the database to store pipeline datarnand ArcSDE as the GIS Server. According to the practical pipeline situations, thernexpert grading method on risk assessment of oil and gas pipeline set by W. KentrnMuhlbauer was modified. An analytic hierarchy process (AHP) was introduced torncomprehensively evaluate the expert grading method, and a categorization methodrnfor the risk of oil and gas pipelines was proposed. Finally, it was demonstrated withrnexamples that this improved categorization method based on Web GIS is morernintuitive and easier to apply.
