摘要： An optical fiber sensor system and method for monitoring a condition of a linear structure such as a pipeline is provided which is capable of providing continuous monitoring in the event of a break in the sensing optical fiber or fibers. The system includes at least one sensing fiber provided along the length of the linear structure, and first and second interrogation and laser pumping sub-systems disposed at opposite ends of the sensing fiber, each of which includes a reflectometer. The reflectometer of the first interrogation and laser pumping sub-system is connected to one end of the sensing fiber. The reflectometer of the second interrogation and laser pumping sub-system is coupled to either (i) an end of a second sensing fiber provided along the length of the linear structure which is opposite from the one end of the first sensing fiber, or (ii) the opposite end of the first sensing fiber. Before any break of the sensing fiber or fibers occurs, each reflectometer redundantly monitors the condition of the linear structure over its entire length. After any such break occurs, each reflectometer will continue to receive signals up to the point of the break from opposite ends of the structure.

摘要： A fiber optic sensor assembly for use on a sub-sea pipeline. The fiber optic sensor assembly is coupled to remotely located equipment by fiber optic cable(s) which extend outside of the pipeline. The fiber optic sensor assembly is affixed to a mounting point on the pipeline. The mounting point is a pipe section having an internal conduit and at least one layer that surrounds the internal conduit for protection and insulation of the internal conduit. A segment of the pipe section has a portion of such layer(s) removed or omitted to define an annular recess. When installed, the assembly has two semi-cylindrical halves that are positioned with the annular recess and coupled together to thereby surround and embrace the segment of the pipe section. The assembly houses a length of optical fiber that is coupled to at least one externally accessible fiber optic connector.
