Temporary Repairs on Pipeline Systems
During a recent discussion, it was suggested to me that some organizations may not be following the current Z662 requirements, (CSA Z662–15, clause 10.12) established for making temporary repairs. They suggested they didn’t really need to follow the rules because “Nobody Else” was following the rules. Apparently, there are still some people in the field who believed that bubble-gum and duct tape constitute a reasonable temporary repair under pipeline regulations, although I wasn’t able to gain any actual examples or names. I remembered my mother asking “If everyone was jumping off the bridge would you follow?”, so I don’t usually give much credence to what “everybody else” is doing as a rationalization for intentional non-compliance. I have usually found the reason people aren’t following requirements is that they are not really aware of them or their implications.
In the past many temporary repairs were conducted using the “seems like a good idea” or “should be good enough” approaches. They were often with little documentation or planning. The rationalization was it was just temporary. The problem that surfaced was that some of those temporary repairs enjoyed some very long lifespans.
