ABSTRACT: The historical context of major industrial disasters provides compelling evidence for the significance of digitizing the permit-to-work systems and control of work processes. Catastrophic events such as the BP Texas City Refinery explosion (2005) and the Piper Alpha disaster (1988) share common root causes directly related to permit-to-work failures. The Ruwais Petrochemical Plant, an ADNOC Group company and a significant player in the world petrochemical, oil, and gas market at some time, was grappling with the limitations of a traditional work control and permit-to-work (PTW) system, a safety and operational risk that drove the organization to transform its work control process. This study was designed to investigate how organizations can maximize Environmental, Health and Safety (EHS) benefits through the implementation of electronic PTW (e-PTW) systems in petrochemical operations. The research employed a single-case study methodology examining the Ruwais Petrochemical Plant implementation experience. A comprehensive audit of the existing paper-based system was conducted to identify systematic deficiencies, followed by gap analysis and market evaluation of available e-PTW solutions. Critical analysis of system functionalities was performed against identified requirements, leading to the selection and implementation of an appropriate digital solution. Process mapping techniques were employed to develop “as-is” and “to-be” workflows, whilst economic analysis examined implementation costs and operational benefits over a 12-month period. The results demonstrated successful resolution of 15 major systematic deficiencies in the paper-based system. Economic analysis revealed total implementation costs of $340,000 offset by annual operational benefits of $210,667, achieving investment recovery by month 19. Through detailed analysis of implementation methodology, operational improvements, and comprehensive economic evaluation, this research offers evidence-based insights for organizations contemplating comparable digital transitions. The results of this research demonstrate that a systematic approach to PTW digitization can address fundamental safety management challenges whilst delivering substantial operational and economic benefits for process industry organizations.
