Abstract
The oil leakage of off-shore pipelines will cause ocean contamination and economic losses. These accidents may happen by the failures of offshore pipelines due to corrosion, impulse and free-spanning. So, it is very urgent on pipeline health monitoring. Fiber optic distributed sensors should be used to know when and where failures may occur. In this study, a feasibility of BOTDA (Brillouin Optical Time Domain Analysis) system is studied on off-shore pipeline distributed strain monitoring influenced by free spanning. Strain distribution of an off-shore pipeline is calculated by numerical analysis and strain measurement experiments are carried on a beam bending test using BOTDA system. BOTDA could be an excellent tool to monitor the long-distance pipeline.
