This paper describes a disruptive continuous monitoring system to detect Corrosion Under Insulation (CUI) risks for every meter of pipeline over large distances. Distributed Fiber Optic Sensing (DFOS) has emerged as a viable non-destructive ATEX-proof solution to detect CUI. ors by depositing metal coatings to the surface of the sensors. Three types of fiber optic sensors were investigated as candidates for corrosion detection: the extrinsic Fabry-Perot interferometer (EFPI), the absolute extrinsic Fabry-Perot interferomete (AEFPI), and the long period grating (LPG). This paper presents a distributed monitoring approach for detection, visualization, quantification, and warning for pipe corrosion using a single-mode telecommunication-grade fiber optic cable as a distributed sensor. The distributed sensor can be deployed on the surface of a pipe to measure. Fiber optic AE sensor was tested due to its anti-explosiveness, fitting to petrochemical plants. Experiment was successful, and one sensor could detect approx. 4,000mm-away corrosion. Our study attempts to detect.
