“…BOTDA sensors were also used to detect and localize buckling on a pressurized pipe by detecting a large Brillouin frequency shift at the location of buckling or a broadening of the Brillouin spectrum . It has also been shown that BOTDA sensors can be used to detect pipe leaks by installing sensors around the pipe prompting a temperature change in the sensors in the event of a leak .…”

SUMMARYDistributed fiber optic sensors have been shown to be promising when used to monitor the structural health of pipes. The body of work thus far has only considered pipes whose cross sections are assumed to remain circular under load. In some applications, the cross section of the pipe has been known to deform when loaded. Subsequent loading on a deformed pipe then generates additional stresses that may have been unaccounted for when designing the pipe. This paper addresses the effects of the initial non-circular cross section of a pipe under internal pressure and its detection with a distributed fiber optic sensor based on Brillouin Optical Time Domain Analysis. This ability of the Brillouin Optical Time Domain Analysis sensor to detect local stiffness irregularities on an out-of-round pipe subjected to internal pressures is also demonstrated.

“…• Distributed Temperature and Strain Sensing (DTSS) units based on stimulated Brillouin scattering, which is the preferred approach due to its long range capability [5]; each of these units is located in a pipeline node such as a pumping station; • Strain and temperature measurement cable sensors, respectively SMC and TMC; TMC also ensures the communication between stations and control centers ( [6], [7], [8]); • Data communication interface between monitoring units and the control centers including the use of the TMC cable; •…”

“…Eisler et al [25] proposed using distributed temperature sensing (DTS) to detect leakage, using optical fibre cables that were embedded in soil, close to the pipeline. Their results [25] showed that embedded fibre sensors can reliably detect and localise movement in the soil that can potentially endanger the pipe. This was found to be quicker and easier than bonding the sensors onto the pipe [26].…”

Leakage is undesirable in water distribution networks, as leaky pipes are financially costly both to water utilities and consumers. The ability to detect, locate, and quantify leaks can significantly improve the service delivered. Optical fibre sensors (OFS) have previously demonstrated their capabilities in performing real-time and continuous monitoring of pipe strength leak detection. However, the challenge remains due to the high labour cost and time-consuming process for the installation of optical fibre sensors to existing buried pipelines. The aim of this paper is to evaluate the feasibility of a submersible optical fibre-based pressure sensor that can be deployed without rigid bonding to the pipeline. This paper presents a set of experiments conducted using the proposed sensing strategy for leak detection. The calibrated optical fibre device was used to monitor the internal water pressure in a pipe with simultaneous verification from a pressure gauge. Two different pressure-based leak detection methods were explored. These leak detection methods were based on hydrostatic and pressure transient responses of the optical fibre pressure sensor. Experimental results aided in evaluating the functionality, reliability, and robustness of the submersible optical fibre pressure sensor.
