The main objective of this methodology is to accurately determine the rate of corrosion growth along a pipeline to development of safe and cost-effective Integrity Management Programs.

TO ACCOMPLISH THAT, WE FOCUS ON THE FOLLOW POINTS:

• Review, align, and compare findings of the data set of in-line inspections to assess the characteristics of the reported anomalies.

• Perform a local growth rate and probabilistic assessments, to establish the internal and external corrosion growth rate.

A number of important decisions depend on the corrosion rate estimates that are used. These include the following:

1. Assess the future integrity of the pipeline using the corrosion growth rates identified.

2. Provide a schedule for future repairs including location, repair activities details and other relevant details.

3. Determination of the optimum re-inspection interval based on the remaining life of uninvestigated corrosion defects.

STANDARD REPORT INFORMATION

1. Review of Inspection Reports

2. Analysis of changes between inspection

3. Matching of Defects

4. Alignment data sheet

5. Local growth rate and probabilistic assessments based on 2 or more inspection data set, using a probabilistic assessment with 80% confidence level, according to indicated by API 1160, to establish the internal and external corrosion growth rate.
