Pipeline security is related to the human life and property, and monitoring the state of pipeline structural health in real time and on-line is the precondition to ensure pipeline security. Optical fiber sensing technology has been developed and applied in various fields, which provides excellent technical support for pipeline security monitoring. In this paper, the principle and key technology of the distributed fiber sensing system, fiber grating sensor, arrayed fiber sensing system, and fiber sensor with the intelligence structure were introduced, and their performances and features were further analyzed. Application of optical fiber sensing technologies in pipeline structure safety monitoring was presented and analyzed thoroughly, including pipeline structural monitoring, pipeline leakage detection, and pipeline internal corrosion monitoring. Research achievements of each technology were illustrated. Merits and defects of these technologies were described, and development trend of these technologies was proposed. It’s pointed out that using optical fiber sensing technologies to monitor pipeline security has bright prospect and many advantages.
