Equipment failure due to corrosion remains one of the significant challenges in maintaining oil refinery asset integrity within the oil and gas processing industry. This study aims to develop a corrosion assessment information system (CAIS), designed to evaluate and visualize the severity of equipment corrosion with a color-coded process flow diagram (PFD) interface. The system facilitates corrosion simulation based on standard damage mechanisms resulting from impurities in crude oil. CAIS significantly enhances the efficiency, accuracy, and cross-functional collaboration in corrosion monitoring activities. The development methodology of CAIS comprises four main stages. First is the compilation, evaluation, and analysis of design and operational data obtained from laboratory testing. The second stage involved process simulation and validation using actual data for each equipment. In the third stage, simulated impurity data are compiled and organized into Excel-based tables for each unit in the crude distillation unit (CDU). Finally, the data are used to identify potential corrosion mechanisms in accordance with American petroleum institute 581 and 571 standards. External validation and system integration within the organizational workflow demonstrate that CAIS is a strategic digital solution supporting risk-based inspection practices and predictive maintenance in PT Kilang Pertamina Internasional Refinery Unit VI Balongan, Indonesia. © SCOG - 2025
