Canada has vast oil and gas reserves. Its supply has grown and is expected to keep growing. The Canadian oil & gas sector needs pipelines, which are considered the safest and the most efficient ways for the transportation of oil and gas. All pipelines have a design life and degradation over time in service. Such degradation can cause failure, which disrupts the oil and gas transportation and is catastrophic to the environment. Monitoring, identifying and responding to an emergency repair are essential. The pipeline isolation system is crucial equipment used during repairs. Rubber gaskets are one of the most important components for such an isolation system. During the pipeline isolation and the subsequent hydrastatic testing following the repair, the gaskets can produce high stresses. Such stresses may cause damage to the pipeline. This project aims to explore the interactions between the gaskets and the pipe and to develop a computer-aided tool to estimate the stresses induced by the gasket in the pipe. Both approaches of computational solid mechanics and experimental mechanics will be used in the proposed project. The project will be carried out with significant industrial support and as an extension of the previous successful collaboration with ProForma Engineering Ltd. (ProForma), an engineering consulting company in Winnipeg, which has been involved in designing the above mentioned specific tools. Although overall Canada's pipeline safety record is strong, safety of pipelines has been the center issue for any pipeline development. The project will contribute to enhancement of pipeline safety by developing a useful tool for pipeline material integrity monitoring and repairing.

加拿大拥有丰富的石油和天然气储量。它的供应量已经增加，预计将继续增长。加拿大石油和天然气行业需要管道，这被认为是最安全和最有效的石油和天然气运输方式。所有管道都有设计寿命，并随着使用时间的推移而退化。这种降解可能导致故障，这会破坏石油和天然气的运输，对环境造成灾难性的影响。监测、识别和响应紧急维修至关重要。 管道隔离系统是维修过程中使用的关键设备。橡胶垫圈是这种隔离系统的最重要部件之一。在管道隔离和维修后的水压试验期间，垫圈可能产生高应力。这种应力可能会对管道造成损坏。本计画旨在探讨垫片与管道间之相互作用，并发展一电脑辅助工具以评估垫片在管道中所产生之应力。计算固体力学和实验力学两种方法将在拟议的项目中使用。该项目的实施将得到重要的工业支持，并作为以前与ProForma工程有限公司（ProForma）成功合作的延伸，ProForma工程有限公司是温尼伯的一家工程咨询公司，曾参与设计上述具体工具。 虽然加拿大的管道安全记录总体上是强有力的，但管道安全一直是任何管道开发的中心问题。该项目将通过开发管道材料完整性监测和修复的有用工具，为加强管道安全做出贡献。
