摘要

Oil and gas pipelines are the most economical and reliable means of long-distance fluid transport worldwide. However, these systems are subject to various forms of degradation that compromise their structural integrity and reduce service life. To address these challenges, composite repair technologies have been extensively developed and applied for pipeline rehabilitation. While the effectiveness of these composite repair systems has been demonstrated through extensive hydrostatic testing and has gained industry acceptance, further improvements in design methodology are essential. This paper comprehensively reviews the analytical approaches used to evaluate composite repaired pipelines, including experimental testing, numerical simulations, and theoretical modeling. The advantages and limitations of each method are systematically summarized, compared, and critically reviewed. Furthermore, this review highlights potential research methods and identifies key challenges and emerging directions in composite pipeline rehabilitation. This review highlights specific data that is needed in the computation of important information for composite-repaired pipeline, such as minimum composite repair thickness, failure pressure etc. The goal is to offer valuable insights into the current state and future developments of composite repair strategies, paving the way for future research.
