In 2010, mechanical integrity personnel started the application of the Direct Assessment (DA) and Inline Inspection Methodologies (ILI) to establish the integrity validation baseline assessments for a Pipeline Integrity Program (PIP) for the pipelines operated within Blocks 12 and 15 by Petroamazonas EP, in Ecuador.

In 2010, mechanical integrity personnel started the application of the Direct Assessment (DA) and Inline Inspection Methodologies (ILI) to establish the integrity validation baseline assessments for a Pipeline Integrity Program (PIP) for the pipelines operated within Blocks 12 and 15 by Petroamazonas EP, in Ecuador.  There were four preconditions which justified the implementation of these methodologies:

1. Following the CFR Title 49, Part-195.6, the Blocks 12 and 15, are classified as Unusually Sensitive Areas (USA’s).

2. Pressure Testing had been the only Integrity Validation Technique applied to all the pipelines and was performed only after the construction of the line to verify the weldments installed but NOT any in-service defect detection.

3. There are pipelines that have been operating for more than 20 years without any integrity assessment beyond the initial construction hydro test.

4. There have been several internal corrosion failures of some pipelines at Blocks 12 and 15 resulting in significant and important economic losses to the operation.

For the implementation of the DA and ILI methodologies the following NACE International and API (American Petroleum Institute) Standard Practices were used as guidelines: NACE SP-0502 for External Corrosion Direct Assessment, NACE SP-0102 and API-1163 for the Inline Inspection Program and NACE MP-ICDA (by the TG-426 and now being published for a late 2015 release) for Internal Corrosion Direct Assessment.
