Mechanical damage involving dents with gouges is one of the leading causes of transmission pipeline failures in terms of both static and cyclic pressure loading. Because of the severity of this defect type, pipeline companies are required to respond to these anomalies by either removing damaged sections or repair using welded sleeves. Composite materials have been used to repair corroded pipelines. Numerous systems have been tested with results being presented in the open literature. The purpose of this paper is to provide the oil and gas industry with an evaluation of composite repair and reinforcement systems to properly evaluate how composite materials should be used to repair and reinforce high pressure pipelines and offshore risers. The paper covers the current state of the art of composite repair and reinforcement, the design process involved in repairing and reinforcing with composites, the analysis methods used, and the testing methods applied. It includes discussions on what critical elements should be evaluated for each composite system, items of caution and concern, and the importance of evaluation to ensure safe long-term performance. Based on a review of available research, composite materials can be used to reinforce damaged pipe materials. The reviewed literature comprises documents on assessing the performance of composite materials, reasons for repairing pipelines, the use of composite materials for offshore applications, the repair of onshore pipelines using composite materials, and strain-based design methods and limit state design. Specific examples include reinforcing mechanical damage subjected to cyclic pressure service and reinforcing corroded offshore risers. Insights gained through the past decade can be used to apply composite repair technology to new systems and structures. The strain-based limit state design method involving composite reinforcement method is ideally-suited for evaluating the level of reinforcement provided by composite materials. Composite reinforcement provides an increase in the fatigue life of unrepaired mechanical damage. But significant care should be taken in repairing actual mechanically-damaged pipelines including considerations of period service history, material quality. The pipeline industry has led the use of these materials as a repair method in the same way the aerospace industry adopted this technology in the 1960s and 1970s. Using a 'lessons learned' approach better positions us to understand the capabilities and limitations of this technology.
