Abstract:
A method for non-intrusive pipeline testing involves constructing the pipeline at a construction location that is above ground, affixing an optical fiber along a surface of a length of the pipeline that is at the construction location, measuring dynamic strain experienced by the length of the pipeline by performing optical interferometry using the optical fiber, and moving the length of the pipeline from the construction location to a different installation location. The optical fiber includes at least one pair of fiber Bragg gratings (“FBGs”) tuned to reflect substantially identical wavelengths with a segment of the optical fiber extending between the FBGs.

Claim (Index 47):
A portable inspection system for non-intrusive pipeline testing, the system comprising:\n (a) a fiber reel on which is wound optical fiber of which a portion is affixed along a surface of a length of the pipeline, the portion of the optical fiber affixed to the length of the pipeline comprising at least one pair of fiber Bragg gratings (\u201cFBGs\u201d) tuned to reflect substantially identical wavelengths with a segment of the optical fiber extending between the FBGs; (b) an optical interrogator optically coupled to the optical fiber and comprising a laser source and a photodetector, wherein the interrogator is configured to perform interferometry by shining laser light along the optical fiber and detecting light reflected by the FBGs, and wherein the interrogator outputs dynamic strain measurements based on interferometry performed on the reflected light; and (c) a signal processing unit electrically coupled to the optical interrogator, the signal processing unit comprising a processor and a computer readable medium communicatively coupled to the processor, the computer readable medium having stored thereon computer program code that, when executed by the processor, causes the signal processing unit to determine an amount of dynamic strain experienced by the length of the pipeline from the dynamic strain measurements that the optical interrogator outputs.
