RELIABILITY ASSESSMENT OF THE SINGLE-STAGE STEAM TURBINE Q201 IN THE STEAREFORMING UNIT AT SONATRACH'S CP1/Z PLANT (ORAN) USING THE FAILURE MODES,EFFECTS, AND CRITICALITY ANALYSIS (FMECA)

This Master's thesis presents a preventive maintenance study of the single-stage steam turbine YR installed at the CP1Z petrochemical complex. Given the critical role of this turbine in the methanol production process (Sections 200 and 700), any failure can lead to complete production stoppage. Through a detailed analysis, we explored the structure and operation of the turbine, then applied the AMDEC (Failure Modes, Effects and Criticality Analysis) method to identify the most frequent failure causes, assess their severity, and propose an optimized maintenance strategy. This approach aims not only to increase equipment availability but also to reduce maintenance costs and improve operational reliability. Our work concludes with a practical maintenance plan that can serve as a foundation for future diagnostic systems based on vibrational signal analysis.
