Predictive crack growth models for pipeline integrity and risk management - Circumferential cracking management

该项目由加拿大能源管道协会（CEPA）成员赞助， 与C-FER Technologies和阿尔伯塔大学合作。该项目旨在评估各种 近中性pH（NNpH）地下水中的环向应力腐蚀开裂（C-SCC） 环境. CEPA C-SCC项目的启动是因为CEPA各成员公司确定了 在他们的完整性管理计划的缺陷，以周向裂纹的威胁。《安排》将 C-SCC项目分为两个阶段。该项目的第一阶段已于2018年底完成， 研究和组织行业知识，以确定差距，并概述整体项目计划， 制定C-SCC管理推荐做法。一个众所周知的行业知识差距是 C-SCC的开始和终止所需的可测量条件。C-SCC项目的第二阶段是 为弥补知识差距而发起的。该项目将由一名博士后和2名博士进行 研究生为期3年。加拿大拥有840，000公里的管道网络 将原油运送到国内和美国的炼油厂。CEPA代表加拿大的输送管道公司 他们在加拿大运营着大约119，000公里的管道，在美国运营着14，000公里的管道。 states. CEPA成员每年运输约12亿桶液体石油产品和5.4万亿桶石油产品。 天然气的需求量。事实上，加拿大每天97%的原油和天然气都是通过 从生产地区到整个北美市场的CEPA成员。管道是一种安全、可靠 和环保的方式来运输石油和天然气。溢出、泄漏和破裂是罕见的， 只有很小一部分通过管道。预计该项目的成果将进一步 提高CEPA成员公司管道运行的安全性和可靠性。

This project is sponsored by members of Canadian Energy Pipeline Association (CEPA) and performed in partnership with C-FER Technologies and the University of Alberta. The project is aimed to evaluate various aspects of circumferential stress corrosion cracking (C-SCC) in near-neutral pH (NNpH) ground water environments. The CEPA C-SCC Project was started because various CEPA member companies identified deficiencies in their Integrity Management Programs to the circumferential crack threat. CEPA has divided the C-SCC project into two phases. Phase 1 of this project was completed at the end of 2018, which was intended to research and organize industry knowledge to identify gaps and outline the overall project plan for development of a C-SCC management recommended practice. One well known industry knowledge gap is the measurable conditions required for the initiation and prorogation of C-SCC. Phase 2 of the C-SCC project is initiated to address the knowledge gap. The project will be performed by one postdoctoral fellow and 2 PhD graduate students for a period of 3 years. Canada has an extensive network of 840,000 kilometres of pipelines carrying crude oil to domestic and U.S. refineries. CEPA represents Canada's transmission pipeline companies who operate approximately 119,000 kilometers of pipeline in Canada and 14,000 kilometers in the United States. CEPA members move approximately 1.2 billion barrels of liquid petroleum products and 5.4 trillion cubic feet of natural gas each year. In fact, 97 per cent of Canada's daily crude oil and natural gas is moved from producing regions to markets throughout North America by CEPA members. Pipelines are a safe, reliable and environmentally friendly way of transporting oil and gas. Spills, leaks and ruptures are rare, representing a tiny percentage of what is flowing through the pipelines. It is expected that outcome of this project will further improve safety and reliability of pipeline operation of CEPA's member companies.
