Reading a failure report without the jargon

A post-campaign assessment is written by technical people for technical people, which is fine right up until it has to justify a decision to someone who does not read them for a living.

Most of it comes down to three things: where the lining went, what mechanism took it, and whether that mechanism was the one the specification assumed. If the answer to the third is no, the specification is what changes.

What we look for is the point where the decision was actually made. Usually it was not on the shutdown floor. It was in a specification written months earlier, against an assumption about service conditions that has since moved.

Every lining lives in a set of conditions before it lives in a vessel: the chemistry it meets, the thermal cycle it rides, the abrasion it takes at the wear face, and the access the crew gets when it is time to put a new one in. Change any one of those and the right answer moves.

Spalling, erosion, corrosion and matrix conversion all look like “the lining wore out” from a distance, and they call for completely different responses. Getting that one distinction out of a report is most of the value in it.

If you are working through this on a vessel of your own, the fastest way in is to bring us the conditions you run in — cycle, chemistry, access, and what failed last time. That is enough to have a real conversation about what to change.
