... period where the pipeline is no longer cathodically protected. We present a statistical approach to this problem, using remote-monitoring data and advanced data analytics techniques. A machine learning model is developed to classify rectifier readings as in their nominal phase or approaching the end...

...Abstract Remote monitoring for cathodic protection (CP) introduces the possibility of performing a detailed investigation on cathodic protection, by obtaining measurement every second during the whole days and the whole weeks, thus allowing to monitor potentials evolution in real time on many...

... via real-time feedback from IR-free potentials measured at critical CP system test points. Key components of this novel approach include the integration of remote monitoring units (RMUs), which are powered by small solar panels, and their ability to collect and transmit real-time data from critical...

... the appropriate corrective actions. Cathodic Protection Overprotection AC interference Remote Monitoring Coupon Reference standard INTRODUCTION If J.dc > 1 A/m2 then J.ac < 30 A/m²; or if J.dc < 1 A/m2 then J.ac < 100 A/m² In the case of underground pipelines, under...

..., annual survey data, remote monitoring data were combined to create a consolidated dataset spanning over ten years for each impressed current cathodic protection (ICCP) rectifier groundbed. Using advanced analytics algorithms applied to ICCP rectifier groundbed sites, weighting factors have been...

... considering different periods of the year. Cathodic Protection 100mV criterion Polarization Remote Monitoring Coupon Reference standard INTRODUCTION Managing Cathodic Protection (CP) in a gas distribution network, is a very challenging activity: the continuous expansion of the network, the urbanization...

... Protection ER-probes stray currents remote monitoring INTRODUCTION The Crossbridge refinery in Fredericia Denmark was built in 1964. The refinery facilities imports and exports of crude, LPG, diesel, gasoline, and other secondary products through four pipelines to the nearby harbor of Fredericia...

...Abstract A remote monitoring system for corrosion, cathodic protection and coating performance has been designed. The system comprises electrical resistance probes for corrosion measurements that also measure cathodic protection parameters such as potentials, currents, spread resistance...

...Physical surveys provide valuable insight on the inspected areas of the structure, whereas remote monitoring gives information from representative positions. The need for physical inspections can be decreased, prioritized, and optimized due to data from remote monitoring. Furthermore, inspections...

... which was commissioned and put into operation in 2012. The segment of interest has been cathodically protected by three rectifiers which have been continuously monitored by remote monitoring units since 2012, with rectifier voltage and current output recorded at least once weekly. In addition, more than...

...Abstract Two remote monitoring & control units (RMCU) and four remote monitoring units (RMU) were installed at the cathodic protection systems on Selden Lock & Dam. Water quality parameters recorded upstream from Selden Lock & Dam were correlated to different remote monitoring unit...

... Equipment Remote Monitoring Coupon Reference Electrode IRfree INTRODUCTION As known, ISO 15589-1 and SP0169 protection criteria refers to IR-Free potentials values to be met by applying cathodic protection to limit corrosion rate and, at the same time, to avoid overprotection: in this respect...
