Research on the Risk Grading Division of Oil and Gas Pipeline Based on WebGIS
Weiqiang Wang, Ming Wu, Dongdong Wang, Fuwei Wang · 2009
The safety management is among the most important management work for oil and gas pipelines. As an alternative, the risk grading division based on WebGIS is being considered to improve safety management. An information management system for oil and gas pipeline based on WebGIS has been established using ArcGIS Server as the developing system of WebGIS, SQL Server as the database to store pipeline data and ArcSDE as the GIS Server. According to the practical pipeline situations, the expert grading method on risk assessment of oil and gas pipeline set by W. Kent Muhlbauer was modified. An analytic hierarchy process (AHP) was introduced to comprehensively evaluate the expert grading method, and a categorization method for the risk of oil and gas pipelines was proposed. Finally, it was demonstrated with examples that this improved categorization method based on Web GIS is more intuitive and easier to apply.
