We present a procedure to estimate the remaining service life of an impressed current groundbed using data analytics techniques to combine the various manually and remotely collected measurements, and rectifier groundbed metadata. Multiple data sources, including commissioning data, 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 calculated to determine the influence of each dataset on the estimated groundbed remaining service life. This work builds on previous presentations at AMPP Corrosion 2021 and 2022, where seasonality and historic trends in rectifier resistance measurements were modelled. By including additional datasets describing the location at the time of installation and the historic survey measurements, a more robust prediction can be made.
