The aim is to improve a software tool for reliability-based quantitative analysis of dents (QuAD) in pipelines developed by Enbridge. QuAD is a tool used to predict the failure for dented pipelines, so that the deteriorated pipeline segments can be reliably identified for excavation to avoid failure. The critical concern with the current QuAD tool […]

Pipelines are a common means to transport oil, gas, and other petroleum products used by citizens in everyday life. These pipelines sometimes traverse slopes, where soil movement caused by erosion or excessive precipitation can lead to pipeline damage which may result in release of product to the environment. The results of this study will allow […]

Pipelines are often subjected to longitudinal stresses due to ground movements such as moving slopes and discontinuous permafrost areas. In these cases, numerical models are used to calculate strain demand which is then compared to tensile and compressive strain capacities (TSC and CSC) which are functions of the pipeline and girth weld material properties. In […]

Corrosion, mechanical damage and cracking are the primary causes of pipeline incidents in Canada. Major incidents can significant impact the public, wildlife, and environment. Over the past ten years, the length of pipelines has increased 11 per cent, but the number of pipeline incidents has decreased 48 per cent. This is largely due to continuous […]
