Composite Repair Validation and Testing: Offshore and Onshore Pipeline Correlation and Findings

Composite wrapping has seen increased usage in both offshore and onshore production assets for the purpose of addressing faults and repairing spots on piping, risers, and pipelines. Validation of repair techniques and products is crucial to ensure the effectiveness and reliability of composite materials utilization. The primary objectives of this study are to establish criteria for validating the Composite Wrap Repair technique, develop a framework for re-validation, and distinguish between materials and protocols used for onshore and offshore pipeline integrity repairs. This study is divided into two parts, examining the principles and standards of Composite Repair products and evaluating their performance in their intended environment. Our product line includes composite repair solutions for both onshore and offshore pipelines. Additionally, we provide a comprehensive analysis of non-destructive testing (NDT) procedures for inspecting and re-validating composite repairs. The project will investigate the use of composite materials for repairing pipelines located both offshore and onshore. We are currently conducting a study on Composite Repair Inspection Techniques, focusing on their on-site application, limitations, and any proof-of-concept findings. We are looking for excellent insights in this area. Through these two component investigations, revalidation criteria and a framework were obtained. A study has been carried out on various composite repair materials and systems that are commonly used in the oil and gas industry. The main emphasis was on understanding their characteristics and evaluating their performance. The study resulted in a deeper understanding of the materials in question. This study sought to examine the mechanical parameters and performance of the chosen products in different load conditions and operating environments, both onshore and offshore. The main goal was to validate the failure mechanisms. Furthermore, a thorough assessment of the main elements has been conducted following the guidelines set by ASTM and ISO standards. This evaluation has been compared to enable further on-site inspections, ensuring the validation of composite wrap repairs currently in use. The evaluation of the proof-of-concept non-destructive testing (NDT) inspection procedures has identified four distinct and promising methods. These methods include contour and digital radiographic scan, infrared thermography, and CT scanner. These methods can be implemented and validated on-site, depending on the desired outcomes. The final section was evaluated to determine the criteria for validation and revalidation, as well as the process of developing them for future use. The study highlights the different reasons behind the failure of composite repair solutions for onshore and offshore pipelines, which are primarily related to the adhesive ingredients and fiber alignment. Prior to deploying each product on assets, a thorough analysis was conducted to assess its performance and behavior in specific operating conditions. This analysis aimed to gain a deeper understanding of the product's failure characteristics. This approach has the potential to effectively safeguard oil and gas assets and mitigate the risk of potential disasters.
