Abstract: Northwest Pipeline Corporation owns and operates a large-diameter natural gas pipeline system thai runs from Igoacio, ( olorado, to Sumas, Washingtoni A 26-inch section of this pipeline crosses the Roan Plateau in western Colorado at Douglas Pass, northwest of Grand Junction, Colorado. I he pipeline alignment crosses a number of landslides of various sizes, ages, and degrees Ol activity. Due K) the considerable deformationsol some slopes, 01 because of occasional large scale landslides, i he integrity of the pipe was disrupted several times in past years. Due to disruptions of service. Northwest decided 10 implemeni certain predictive and mitigative measures ihal would enable the Operations group to maintain the pipe in its present location and minimize the risk of failures. This paper presents a method to predict potential pipe failure at a specific location and the implementation oi early mitigating measures to prevent the failure.
