Perform an assessment and/or rerating of equipment that is designed and constructed following procedures provided to the standard API 579-1/ASME FFS-1, Fitness-For-Service to help ensure the safe and reliable operation of pressurized equipment used in oil & gas, petrochemical, and chemical facilities.

A selection will be made from the most commonly available and accepted defect assessment methods (i.e., ASME B31.G, Simplified RSTRENG [0.85 dL] or Effective Area Method).

SPECIFIC OBJECTIVES

• Assess the significance of the corrosion features reported in the pipeline for operation at the current Maximum Allowable Operating Pressure (MAOP).

• Assess the significance of any other feature reported in the pipeline.

• Identify any high-risk areas on the pipeline which require an immediate investigation or repair.

• Assess corrosion growth. In addition, local growth rate and probabilistic assessments are both examined, to establish an internal and external corrosion growth rate.

• Assess the future integrity of the pipeline using the corrosion growth rates identified in the corrosion growth assessment.

• Provide the location and other relevant details for immediate repairs (If it is necessary).

• Provide schedule for future repairs including location, repair activities details and other relevant details. (If it is necessary).

• Recommend an ILI re-inspection interval.

STANDARD REPORT INFORMATION

1. Diagnostic Review of Reported Defects

2. Standard Metal Loss and Manufacturing Defect Assessment

3. Standard Dent Assessment

4. Girth Weld Criticality Assessment

5. Immediate Integrity

6. Corrosion Growth Rates (probabilistic assessment)*

7. Remanente Life Assessment / Future Integrity Plan

8. ILI Re-inspection interval

*Note: The standard FFS includes a corrosion growth rate based on 1 inspection data set, using a probabilistic assessment with 80% confidence level, according to indicated by API 1160. A local growth rate will be considered, if there is a Run Comparison Assessment.
