“…In [17] the authors have implemented the loop integrated Mach-Zehnder interferometer for an optical fibre-based vibrational sensor in pipeline monitoring and leakage localisation. The implemented system was tested with a 40 m steel field pipeline and the obtained results show good performance, with an average percentage error of 0.4% and 2.64% at 2 bar and 3 bar of pressure, respectively [18].…”

“…Several pipeline leak detection methods have been proposed during the last decades using different working principles and approaches. Existing leakage detection methods are: acoustic emission [13,14,15], fibre optic sensor [16,17,18], ground penetration radar [19,20], negative pressure wave [21,22,23], pressure point analysis [24,25,26], dynamic modelling [27,28], vapour sampling, infrared thermography, digital signal processing and mass-volume balance [29,30,31,32,33]. These methods have been classified using various frameworks.…”

Pipelines are widely used for the transportation of hydrocarbon fluids over millions of miles all over the world. The structures of the pipelines are designed to withstand several environmental loading conditions to ensure safe and reliable distribution from point of production to the shore or distribution depot. However, leaks in pipeline networks are one of the major causes of innumerable losses in pipeline operators and nature. Incidents of pipeline failure can result in serious ecological disasters, human casualties and financial loss. In order to avoid such menace and maintain safe and reliable pipeline infrastructure, substantial research efforts have been devoted to implementing pipeline leak detection and localisation using different approaches. This paper discusses pipeline leakage detection technologies and summarises the state-of-the-art achievements. Different leakage detection and localisation in pipeline systems are reviewed and their strengths and weaknesses are highlighted. Comparative performance analysis is performed to provide a guide in determining which leak detection method is appropriate for particular operating settings. In addition, research gaps and open issues for development of reliable pipeline leakage detection systems are discussed.

“…The distributed vibration-based fiber optics can be used in monitoring leakages in buried pipelines ( Jin et al 2016). Png et al (2018) proposed a simple and handy acoustic vibration sensing device to monitor water pipelines. The sensor was cased with a polyvinyl chloride base for protection and handy use.…”

This study reviews the state-of-the-art application of fiber optics in water distribution networks for leak detection and localization. The use of fiber optics in the oil and gas sector has been well-established; however, its potential in water pipelines is not evident owing to limited research. This study, therefore, presents the research developments of fiber optics in water leak detection and localization using the mixed methodology approach by integrating bibliometric and systematic analyses. A scientometric analysis is carried out to analyze the science maps of (1) journal sources, (2) contributing countries, and (3) co-occurrence of influential keywords. The systematic analysis evaluates the use of eight types of fiber optics, such as accelerometer-based fiber optics and hydrophone-based fiber optics, in water leak detection and localization. The review reveals five important directions for future research such as real network-based studies and the development of hybrid techniques.

“…It relies strongly on demodulation technology; however, demodulated signals are susceptible to interference from external conditions. Optical time-domain reflectometry detection technology uses single-mode optical fibers, handling single-mode optical fiber can be costly in terms of splicing and slicing tools as well as the complexity of introducing structures on the side [23,24]. In the existing sensors, the conversion of a liquid leakage event into a change in temperature or strain is time-consuming, which affects the real-time performance of the system.…”

“…In the existing sensors, the conversion of a liquid leakage event into a change in temperature or strain is time-consuming, which affects the real-time performance of the system. Special structures, such as cones [24] and gratings, can be machined on the fiber [15,16], which can improve the measurement accuracy of the sensor and reflect changes in the refractive index. However, such structural processing is complicated, which increases costs.…”

In this study, a novel high-reliability liquid leakage sensor with a V-shaped defect coupling structure (VDCS) is proposed and experimentally demonstrated using polymer optical fibers (POFs) based on a light-emitting diode (LED) side-coupled light source. Liquid leakage detection is achieved with changes in the refractive index as the coupling medium transforms from air to liquid. The LED lamp both provides a light source and assists positioning. The coupling efficiency of the POF liquid leakage sensor varies with the depth and angle of the VDCS. Experimental results show that the coupling efficiency of the POF leakage sensor is high when the VDCS depth is 0.5 mm and the inclination angle is 60°. Compared to an existing leakage sensor with a hole-shape defect coupling structure (HDCS), the VDCS has a faster response time and higher reversibility. The average reliability of the liquid leakage sensor is increased to 5.92 μW/mL. This research provides a powerful structural reference for POF side-coupling leak measurement and can also be applied to the fields of gas and humidity sensing.
