Abstract
A fluid pipeis monitored using a distributed acoustic sensing (DAS) fibreprovided within pipe. The DAS fibreis coupled at one end to a light emitterand a light detector. The light emitteremits light pulses into the DAS fibre. The light detectordetects backscattered light so as to provide an indication of the vibration experienced by each section of the DAS fibreand thus of vibration characteristic of particular pipe events including leaks of the pipe. The DAS fibrein a pipecan also be used to locate the route of a buried pipeby successively tamping the ground surface at a number of locations A-E in the vicinity of the suspected route of the pipeand comparing the tamping vibrations detected from each location A-E.
