Cathodic protection groundbeds often exhibit prolonged, unpredictable deterioration, gradually degrading before abrupt service loss. Another challenge is that theoretical design life may not reflect real-world conditions. We present an operator-led predictive model that integrates historical inspection record and key rectifier metadata to help predict groundbed depletion through a variety of systems. A 3 level assessment depending on available inputs where Monte Carlo simulations—planned for future implementation—will capture variability in consumption rate, efficiency and uncertainty. Retroactive application to known failed or degrading groundbeds shows strong correlation across two implemented levels of our three-tier assessment framework, with minor discrepancies due to extrinsic factors. This approach enhances outage forecasting, improves cathodic protection reliability, and supports budgeting for maintenance and replacement of systems before groundbed failure
