Buried pipelines sloping ground potential

项目摘要

Oil and gas pipelines generally traverse over a large distance through various ground conditions, from relatively flat areas to sloping grounds such as crossing hills, mountain ridges and rivers. Ground deformation/slope failure and upheaval buckling during operation pose a major threat to the structural integrity, safety and operability of the pipelines. Canada has a network of approximately 115,000 km of underground energy transmission pipelines that operates every day to transport oil and natural gas. The current guidelines recommend using simplified approaches, which have some limitations. In the proposed project, numerical analysis and laboratory tests will be performed for a better understanding of these complex mechanisms to develop improved methods for assessing the response of pipelines in the sloping ground and that might experience buckling. Two PhD and one Master's candidates will be supported through this research grant. The outcomes of the research will be sought by stakeholders including engineering service companies, operators, oil and gas companies, regulatory agencies and academia to address constraints (e.g. technical, economical or logistical) and satisfy accepted risk and safety targets (e.g. societal, environmental).

石油和天然气管道通常在各种地面条件下，从相对平坦的区域到山坡，山脊和河流等各种地面条件，通常会在较大的距离内穿越。操作过程中的地面变形/坡度故障和动脉屈曲对管道的结构完整性，安全性和可操作性构成了重大威胁。加拿大拥有大约115,000公里的地下能源传输管道网络，每天运行以运输石油和天然气。当前的指南建议使用具有一些局限性的简化方法。在拟议的项目中，将进行数值分析和实验室测试，以更好地理解这些复杂机制，以开发改进的方法来评估倾斜地面中管道响应的方法，并且可能会经历屈曲。这项研究赠款将支持两名博士学位和一名硕士候选人。该研究的结果将由包括工程服务公司，运营商，石油和天然气公司，监管机构和学术界在内的利益相关者寻求，以解决限制（例如技术，经济或后勤）以及满足公认的风险和安全目标（例如，社会，环境，环境）。
