RBI, CMP & OSI STUDY AT SHAYBAH NGL
Objective
RBI Study
- Establish the current risk levels for equipment items and in-plant piping in order to reduce risk through inspection.
- Improve cost-effectiveness of inspection resources.
- Provide recommendations and propose improvements to manage the operational risk to acceptable industry levels; ALARP (As Low As Reasonably Practical) and optimized future inspection plans.
CMP Study
Development of an Effective corrosion management strategy that results in:
- Improved plant integrity and safety.
- Reduced corrosion failures.
- Optimized mitigation, monitoring and inspection expenditure.
OSI Program
The main objectives of establishment/optimization of the OSI Program are:
- To validate if all equipment items and piping systems (included under RBI assessment) are covered in the OSI program as per applicable P&IDs.
- Review and validate the OSI program based on API RBI study and applicable damage mechanisms.
- Identify existing gaps, and then give suggestions to revise or update the OSI program.
