• Ensure compliance with ADNOC Offshore process safety standards. 

• Conduct relief, flare, pressure drop, and hydraulic calculations. 

• Manage process safety deliverables (safeguarding, cause & effect, PSV sizing). 

G. Documentation & Review 

• Prepare and review process narratives, line lists, valve data sheets, PFDs/P&IDs. 

• Ensure deliverables of SOW are submitted on time. 

• Valid ate deliverables from FEED and update as per Addendum. 

• Provide input to control narratives, operating manuals, commissioning procedures. 

H. Support to Construction / Commissioning (as needed) 

• Support construction team in resolving process -related site issu es.

• Provide technical guidance during pre -commissioning and commissioning. 

• Verify process performance during start -up and system integration testing.
