Faulty PigSig?

The article says "failed component" and "pigging not underway at the time". Sounds like something broke or rotted out (but normally when they see corrosion damage the tell the PR guy to use the word "corrosion").

Yet another reason not to install pig sigs, especially what looks like a buried one...

Yes, "A failed component on a location indicator tool". That could mean an number of things, but given that inspection pigging was not underway at the time, that would eliminate portable pig locators and the like, so I think that narrows it down to journalism speak for "PigSig". Is there anything else it could be?
