A lot of information exists on the API
http://www.api.org/products-and-services/individual-certification-programs/certifications/api1169 and INGAA
http://www.ingaa.org/File.aspx?id=29559&v=355c3f71 websites on how to get certified and what certifications INGAA and CEPA member companies will require of our inspectors. Hopefully all you guys who work pipeline are getting yours. It's no where as difficult as the CWI and those who hold the certifications will have more work opportunities.
In addition to CEPA and INGAA, I understand American Gas Association (AGA) is also currently working on a white paper on pipeline inspection in which they will also endorse the certifications for pipeline construction inspectors. The liquid pipeline is already endorsing it. With AGA also endorsing it, all major liquids or gas pipelines in North America will be inspected with API 1169 certified inspectors.
API 1169 is being established as the basic requirement that all levels of inspector will need to have. In addition to it, welding inspectors will be required to have AWS CWI. Coating inspectors will be required to have NACE CIP Level 2. Many anticipate that the old CPWI John Wormley School of welding inspection certification will no longer be recognized on major pipeline construction projects.
IMHO, it is clear that improvements and standardization in experience requirements, competency, qualifications and certifications of inspectors across the pipeline industry can ultimately improve the quality of construction, integrity, reliability and longevity of pipelines as well as the safety of members of the public who live and work near these assets. All of us and our families will be better off for it.
