| Summary: | Metallic structures, such as pipelines and storage
tanks, are among the most critical infrastructures worldwide
for transporting liquids or gases. Conventional on-site
inspections and monitoring methods are not effective in
detecting sudden or occasional failures due to corrosion in
these metallic structures. Therefore, a continuous monitoring
system is necessary to provide early warnings for immediate
mitigation and to monitor the cathodic protection (CP)
operating conditions and its surrounding environments. A test
post remote monitoring system, equipped with voltage,
humidity, and battery capacity sensors is developed and
integrated with an industrial internet of things (IIoT) platform.
Node-RED was utilized to develop an interface for monitoring
parameters collected from the system via a communication
protocol. The findings indicate that the remote monitoring
system can measure potential readings with a low error of
within 1% comparable to a conventional multimeter.
Furthermore, the system enables monitoring the polarization
and depolarization potential behavior during cathodic
protection operation conditions on a pipeline. |
