Scenario
A 10 year internal Inspection of a Lagged Storage Tank carried out to a WSE written by 3rd Party.
The inspection was carried out and pitting was found. Plant Engineer with 15+ year’s industry experience had tank repaired and Dye Pen test, all done on the internal walls of the tank.
OK nothing unusual there.
However Engineer with 1 year industry experience asked the Plant Engineer the following questions,
• What standard was the repair done to,
• Did he get the welder qualification, WPS, information on the type of welding wire/rod used
• Did he check the external of the tank in the welded area (lagging would have to be removed. Removing lagging is not part of the WSE)
• Was a UTS done.
The answer to all was no because as the competent person he believed that it was not needed because he had followed the WSE done by the 3rd party. (The plant engineer is now going to get the welder information)
Who is the more competent?
