Han Xiao-ming · Acta Petrologica Sinica · 2010
The earthquake occurred in Wenchuan County of Sichuan Province resulted in seriously secondary geological disasters such as landsides and quake-formed lake.The Lan-Cheng-Yu pipeline passing through the earthquake area had also been seriously affected.For protecting the pipeline safety and supplying oil for disaster area,the PetroChina Pipeline Company applied the integrity technology to identify the threats affecting the pipeline safety and assess the risk grade.The protection and mitigation plans were developed.An integrity management program based on GIS was also used to graphically display the assessment results and provide information for operators to effectively allocate resources for appropriate prevention,detection and mitigation activities of safety improvement.
