Holistic Approach Reliability Evaluation Unpiggable

项目摘要

The reliability- and risk-based corrosion assessment of unpiggable oil and gas pipelines is a challenging taskbecause such pipelines are inaccessible to inspection tools. Various methods including the samplingexcavation, hydrostatic pressure testing and above-ground survey techniques are commonly used to collectpartial information about the corrosion conditions of unpiggable pipelines. Therefore, there is a need fordeveloping a holistic approach that allows pipeline operators to effectively integrate data obtained fromdifferent sources to obtain the complete information about the corrosion condition and facilitate the reliabilityevaluation and risk-based integrity management of unpiggable corroding pipelines. The objective of theproposed project is to carry out exploratory investigations toward the development of such an approach. Theproposed project will employ the Bayesian methodologies for updating the density and sizes of corrosionfeatures on unpiggable pipelines based on data obtained from various sources. The research will be carried outin collaboration with the industry partner, JANA Corporation in Aurora, Ontario, and will train onepostdoctoral fellow for a duration of six months. The research outcome will facilitate the integritymanagement of unpiggable oil and gas pipelines and improve the safety, reliability, and economical viability ofthe vast oil and gas pipeline networks in Canada.

对石油和天然气管道的可靠性和基于风险的腐蚀评估是一个具有挑战性的任务，因为这种管道无法访问检查工具。各种方法，包括采样量，静液压测试和地上调查技术，通常用于收集有关无关管道腐蚀条件的派种信息。因此，有必要开发一种整体方法，该方法允许管道运营商有效整合从各个方面的来源获得的数据，以获取有关腐蚀条件的完整信息，并促进了可靠性评估和基于风险的完整性管理，对无形的腐蚀管道进行了管理。该项目的目的是为开发这种方法进行探索性研究。该项目将采用贝叶斯方法学来根据从各种来源获得的数据来更新无法配置管道上的腐蚀作用的密度和尺寸。该研究将与安大略省奥罗拉（Aurora）的行业合作伙伴Jana Corporation合作进行，并将在六个月内培训Onepostdoctoral研究员。该研究结果将促进不可使用的石油和天然气管道的完整性管理，并提高加拿大庞大的石油和天然气管道网络的安全性，可靠性和经济可行性。
