The proposed project is aimed at improving the structural integrity management of pressurized steel transmission pipelines with respect to two major threats, namely metal-loss corrosion and third-party interference. The specific objectives of the research are to 1) develop procedures to determine the minimum or optimal number of field excavations required for validating the accuracy of inline inspection (ILI) data for corrosion defects, and Investigate measurement errors associated with the ILI-reported depth and length of the corrosion defects; 2) develop an accurate, practical burst capacity model for corroded pipelines based on a large database of burst pressure capacities established through extensive high-fidelity finite element analysis (FEA) that are validated by full-scale burst tests, and 3) improve the pipeline integrity management practice with respect to the third-party interference by improving the model for estimating the probability of third-party interference and methodologies for evaluating the impact force and puncture resistance of the pipeline. The research will be carried out by two co-principal investigators, Drs. H.P. Hong and W. Zhou, over a period of three years under the support of TransCanada and NSERC, and will involve the training of two postdoctoral fellows and three PhD students. The research outcome will allow TransCanada and the Canadian pipeline industry to more effectively manage the integrity of transmission pipeline networks, and contribute to the long-term prosperity of the Canadian society. The proposed project further offers a unique training opportunity for the PDFs and PhD students involved in that they will develop excellent technical skills by carrying out state-of-the-art research of high practical relevance, and gain valuable practical experience and knowledge by interacting with experienced pipeline integrity engineers on a regular basis. This training will enable them to become the next-generation stewards of the Canadian pipeline networks.

拟议的项目旨在改善相对于两个主要威胁，即金属损坏腐蚀和第三方干扰的加压钢传输管道的结构完整性管理。 研究的特定目标是1）制定程序，以确定验证腐蚀缺陷的验证准确性（ILI）数据所需的最小或最佳田间发掘数量，并研究与ILI-RETEDSTED腐蚀深度和腐蚀缺陷长度相关的测量误差； 2）基于通过广泛的高保真有限元分析（FEA）确定的巨大爆发压力能力数据库，为腐蚀管道开发准确，实用的爆发能力模型，该数据库通过全面的爆发测试来验证，这些元素分析（FEA）通过全尺度的爆发测试验证，3）改善管道完整性管理实践，以估算第三方的影响，以估算第三方的概率和第三个方法的方法，以估算第三局部的方法和第三名的方法，该模型是概率和方法。管道的阻力。 这项研究将由两名联合首席调查员博士进行。 H.P.在TransCanada和Nserc的支持下，Hong和W. Zhou在三年的时间内，将涉及两名博士后研究员和三名博士学位学生的培训。 该研究结果将使TransCanada和加拿大管道行业能够更有效地管理传输管道网络的完整性，并为加拿大社会的长期繁荣做出贡献。 拟议的项目进一步为参与的PDF和博士生提供了独特的培训机会，他们将通过进行高级实践相关性的最先进研究来发展出色的技术技能，并通过定期与经验丰富的管道完整性工程师进行互动，从而获得宝贵的实践经验和知识。 这项培训将使他们成为加拿大管道网络的下一代管理者。
