Discrimination of Internal Wall Thinning in Pipeline with PPP-BOTDA Based Distributed Optical Fiber Sensors

Abstract:

In this paper, the new developed PPP-BOTDA based distributed optical fiber strain sensors are used to monitor wall thinning in pipeline. Furthermore, according to the sensing behavior of PPP-BOTDA, a damage detection method is proposed, by using the measured strain distribution of PPP-BOTDA, the thinning area in pipeline wall can be located and quantified by proposed method, furthermore, the accuracy of proposed method is evaluated.
