The proper functioning of static, rotating, and electrical equipment plays a vital role in ensuring the safety and uninterrupted production process within an oil refinery environment. In this research, an all-encompassing framework of an Equipment Health Score (EHS) will be formulated through a combination of lifecycle condition, operations data, maintenance records, and equipment reliability into a 0–100 score. This method will incorporate the use of initial health, modifier health, and reliability measures as the basis for evaluating different assets within an oil refinery environment. Different equipment-related scores will be based on the following data. The methodology is illustrated using selected refinery equipment, including storage tanks, piping systems, and pumps. The storage tank attained the highest health score of 85.99, with the piping system scoring 80.64, whereas the pump attained the lowest health score of 66.70. The low health score attained by the pump shows that having a good current condition score does not mean good health if other criteria such as lifecycle and reliability are not well met. The developed methodology can therefore be used for the purposes of easy comparisons among different classes of equipment, prioritization of equipment maintenance, and risk-based decisions. The developed methodology has also provided a platform for integration with condition-based maintenance, computerized maintenance management system, and asset readiness evaluation. Future research will concentrate on the validation of the methodology over a long period of time in various refinery plants, fine-tuning of weighting factors and thresholds, and integration with machine learning and predictive maintenance.
