“…An internal corrosion monitoring technique based on distributed strain measurement using optical frequency domain reflectometer (OFDR) technology was proposed by [ 27 ]. The sensor was tested to detect and locate uniform and local corrosion in pipelines based on the reduction that occurs to the pipeline wall thickness when it corrodes.…”

“…The job of the optical fiber, attached to the pipeline, was to measure pipeline hoop strain. In [ 27 ], it was postulated that the reduction in pipeline wall thickness can be obtained by monitoring the change in the pipeline hoop strain. The problem is that the hoop strain can also change due to changes in the pipeline temperature or internal pressure.…”

Corrosion in the oil and gas industry represents one of the major problems that affect oil production and transportation processes. Several corrosion-inspection technologies are in the market to detect internal and external corrosion of oil storage tanks, but inspection of storage tanks occurs every 3 to 7 years. In between inspection interval, aggressive corrosion can potentially occur, which makes the oil and gas industry vulnerable to accidents. This study proposes a new internal corrosion detection sensor based on the magnetic interaction between a rare-earth permanent magnet and the ferromagnetic nature of steel, used to manufacture oil storage tanks. Finite element analysis (FEA) software was used to analyze the effect of various sensor parameters on the attractive force between the magnet and the steel. The corrosion detection sensor is designed based on the FEA results. The experimental testing of the sensor shows that it is capable of detecting internal metal loss due to corrosion in oil storage tanks within approximately 8 mm of the internal surface thickness. The sensor showed more than two-fold improvement in the detection range compared to previous sensor proposed by the authors. Furthermore, the sensor of this paper provides a monitoring rather than occasional inspection solution.

“…Water supply and drainage pipelines in utility tunnel belong to concealed and long‐distance engineering 1,2 . Due to aging, fracture, corrosion, improper materials, and poor construction, 3–6 pipeline leakage in utility tunnel is unavoidable, 7 which will not only waste precious water resources but also affect people's normal production and life 8 and even cause safety problems of other pipelines in utility tunnel 9 . Therefore, it is of great significance to explore the real‐time in situ technology for leakage monitoring of water supply and drainage pipelines in utility tunnel 10 …”

Summary The water distribution systems in utility tunnel are considered as the lifeline projects. The leakage monitoring of water supply and drainage pipelines is closely related to the overall operation and safety of the utility tunnel. However, conventional pipeline leakage monitoring methods are difficult to realize the monitoring of ordinary temperature liquid and small leakage. Moreover, they also have problems with noise interference, high false alarm rate, and high cost. In order to overcome the shortcomings of the conventional methods, the evaporation‐enhanced Fiber Bragg Grating (FBG) temperature sensing (EETS‐FBG) method was proposed as a new type of leakage monitoring solution according to the principle of the psychrometer. This method utilizes the evaporative cooling characteristics of water‐absorbing porous materials and the FBG temperature sensors to realize leakage monitoring. On the basis of experiments, the feasibility of this method is explored, and the effects of wind speed, liquid temperature, and leakage volume on monitoring results are analyzed. The experimental results show that the EETS‐FBG method can monitor the temperature difference of 0.97–8.55°C in the humidity of 51.0–90.8%RH, and the measured values are in good agreement with the theoretical values, which shows that the method has good feasibility. In addition, the measured temperature difference increases with the ambient wind speed, while the leakage volume and water temperature have no obvious effect on the temperature difference, which shows that the method has good reliability and universal applicability. This method has outstanding advantages for normal temperature liquid and small leakage monitoring and is worthy of application and promotion.

“…In the last decades, the research on health and usage monitoring systems (HUMS) is driven by the need for aircraft operational life extension. HUMS is intended to monitor the health state of a structure and its consumed life, based on a series of permanently installed sensors 1–3 . In this framework, knowledge of the real load spectra 4 to which a structure is subjected during its service life and thus the associated strain and stress fields are mandatory for computing the consumed life and exploiting HUMS system data on real structures 5–7 .…”
