Bad Actor Definition

Bad Actor Definition

Bad Actor Definition

Dear Engineering Professionals,

I am working on improving our steam turbine reliability in Downstream (O&G). We are looking into developing a Bad Actor list so that we can work with Maintenance Engineering to resolve problems as they arise.

What would be a good definition of Bad Actor related to equipment?

Highly Appreciated,


RE: Bad Actor Definition

"Bad" actor in what sense? There are intentionally "bad" actors, and inadvertently "bad" actors.

In my mind, anyone can be a "bad" actor who has access to any equipment or interface to same equipment that can cause cessation of operation or damage to the direct equipment or personnel, or equipment connected further downstream or personnel downstream.

RE: Bad Actor Definition

An example of a bad actor is a piece of equipment that fails frequently. A pump that fails frequently due to seal leaks. This pump would be marked as a bad actor for further assessment by Engineers.

RE: Bad Actor Definition

Replacement parts with a long lead time.
Parts, equipment or tools with a short design life or otherwise limited usefulness.
Items that require excessive maintenance, testing or inspection.

RE: Bad Actor Definition

Your Maintenance folks should already have this. It's called a Pareto Analysis looking at historical data like cost to repair or downtime.

Good Luck,

RE: Bad Actor Definition

thanks for the responses. Highly appreciated

RE: Bad Actor Definition

We had this one component that we used on 10 of our boilers, it was critical to the efficient operation of the plant and automatic operation of the plant. Steam supply pressure could get very erratic depending on the operators skill level and fluctuations in demand. This would cause lots of scrap production/stoppages in food retorts etc. It came from overseas with a lead time of 3 months and we were only allowed to have two of them in the stores because of how expensive they were. I think that component qualified as a bad actor.

RE: Bad Actor Definition

Check with your maintenance guy , he should use a maintenance program computerized , taking care of curative and preventive maintenance .
In this case he should have in his hands a way to extract all the downtime per equipment and all possible graph.
Good luck
