I’m betting This is no accident
Could be.
But it was just down for maintenance.
One tiny little slip or mistake in the many plumbing connections, valves, controllers, wiring, connections, etc., and you have a big problem.
With HR everywhere bending over to hire the "right" folks to meet the insane ESG rules, the chance of a screw up increases.
It could also have been operator error, very easy to happen.
When I was a power plant operator, and later an electro-mechanical technician, I always re-thought through everything I was about to do or had done.
One fellow who chastised me for this encountered karma when a couple of weeks later he caused extreme havoc by not paying attention to detail.
Shut the plant down for 2 weeks while we cleaned up 4 feet deep of #6 bunker fuel.
I have goofed up too, but either caught it in time, or it was very minor.
The most dangerous time in a refinery is the start up after downtime for maintenance.
Me too.
