RBI, CMP & OSI Study at Jazan Refinery
Location:Kingdom of Saudi Arabia
Services:Risk Based Inspection (RBI)
Corrosion Management Program (CMP) Study
On-Stream Inspection (OSI) Program
Saudi Aramco – in collaboration with SK Engineering & Construction Co. Ltd (SK E&C) - approached Velosi to carry out a detailed Risk Based Inspection (RBI), Corrosion Management Program (CMP) Study, and On-Stream Inspection (OSI) Program for their Jazan refinery, integrated marine terminal and power plant project located in the Jazan province in Saudi Arabia.
RBI Study - To establish the current risk levels for equipment items and in-plant piping in order to reduce risk through inspection. We also have improved cost-effectiveness of inspection resources and provided recommendations and proposed improvements to manage the operational risk to acceptable industry levels; ALARP (As Low As Reasonably Practical) and optimized future inspection plans.
CMP Study -Develop an effective corrosion management strategy that resulted in the improvement of plant integrity and safety. We have also reduced corrosion failures, and optimized mitigation, monitoring and inspection expenditure of the Shaybah NGL Plant.
OSI Program -Validate all equipment items and piping systems (included under RBI assessment) that are covered in the Open Systems Interconnection (OSI) program as per the applicable Piping and Instrumentation Diagrams (P&IDs). We have reviewed and validated the OSI program based on API RBI study and applicable damage mechanisms. Also, Velosi has identified existing gaps, and then provided suggestions to revise or update the OSI program.
