项目摘要

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.

该项目由加拿大能源管道协会（CEPA）成员赞助，并于与 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) 地下水中周向应力腐蚀开裂 (C-SCC) 的各个方面环境。 CEPA C-SCC项目的启动是因为各个CEPA成员公司确定了其完整性管理计划中的缺陷导致了圆周裂纹威胁。 CEPA已划分 C-SCC项目分两期进行。该项目一期工程已于2018年底竣工，预计研究和整理行业知识，找出差距并概述总体项目计划制定 C-SCC 管理推荐实践。一个众所周知的行业知识差距是 C-SCC 启动和终止所需的可测量条件。 C-SCC项目的第二阶段是旨在解决知识差距。该项目将由一名博士后和两名博士执行研究生，学制3年。加拿大拥有由 840,000 公里管道组成的广泛网络将原油运送到国内和美国炼油厂。 CEPA代表加拿大输油管道公司他们在加拿大运营约 119,000 公里的管道，在美国运营约 14,000 公里的管道国家。 CEPA 成员国运输了约 12 亿桶液体石油产品和 5.4 万亿桶每年立方英尺天然气。事实上，加拿大每日 97% 的原油和天然气都是通过运输方式运输的由CEPA成员从产区运往整个北美市场。管道是安全可靠的以及环保的石油和天然气运输方式。溢出、泄漏和破裂很少见，代表流经管道的水只占很小的比例。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。
