A central chapter in the 2021 WMS PDF covers the synergy between the WMS and ADNOC’s PTW system (eSIM or legacy systems). Every maintenance job must be linked to a specific permit (e.g., Cold Work, Hot Work, Confined Space Entry). The system blocks work execution until all isolations (LOTO – Lockout/Tagout) are verified. Diving Certificate: For underwater operations
A detailed article on the Implementation of the Integrated WMS outlines the system's architecture and future roadmap.
