Abstract

Damage detection in pipeline system is one of the most important goals for energy companies. As the pipeline network continues to age, monitoring and maintaining its structural integrity is needed. A few methods of nondestructive evaluation (NDE) are currently used for this purpose, but numerous accidents over the past several years have led to significant costs and fatalities, indicating that NDE techniques may not be sufficient. Researchers and owners believe that a structural health monitoring (SHM) system would enable pipeline operators to continuously monitor the structural integrity of their networks. This paper gives critical review about impedance-based structural health monitoring. Impedance method is one of the SHM system detection techniques that implemented using the piezoelectric patches, avoiding the necessity for two separate sensor arrays. Because piezoelectric patches are flexible and resilient, they can potentially be permanently bonded to the curved surface of a pipeline’s main body. This permanent installation allows for the continuous monitoring of the pipeline system and reduces the costs associated with implementing NDE techniques, such as excavation to gain direct access to the pipeline.
