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。其供应量已经增长，并且预计将继续增长。加拿大石油和天然气行业需要管道，管道被认为是最安全、最有效的石油和天然气运输方式。所有管道都有设计寿命，并且会随着使用时间的推移而退化。这种降解可能会导致故障，从而扰乱石油和天然气运输并对环境造成灾难性影响。监控、识别和响应紧急修复至关重要。 管道隔离系统是维修过程中使用的关键设备。橡胶垫圈是此类隔离系统最重要的组件之一。在管道隔离和修复后的后续水压测试过程中，垫片会产生高应力。这种应力可能会导致管道损坏。该项目旨在探索垫片和管道之间的相互作用，并开发一种计算机辅助工具来估计垫片在管道中引起的应力。该项目将使用计算固体力学和实验力学两种方法。该项目将在重要的工业支持下进行，并作为之前与温尼伯工程咨询公司 ProForma Engineering Ltd. (ProForma) 成功合作的延伸，该公司参与了上述特定工具的设计。 尽管加拿大整体管道安全记录良好，但管道安全一直是任何管道开发的中心问题。该项目将通过开发用于管道材料完整性监测和修复的有用工具，为提高管道安全做出贡献。
