The faulty wire is the root cause. If it didn't trigger the sequence of events, all of the other things wouldn't have happened. And it's kind of a tricky thing to find, so that's an exciting find.

The flushing pump not restarting when power resumed did also cause a blackout in port the day before the incident. But you know, looking into why you always have two blackouts when you have one is something anybody could do; open the main system breaker, let the crew restore it and that flushing pump will likely fail in the same way every time... but figuring out why and how the breaker opened is neat, when it's not something obvious.

Operators always like to just clear the fault and move on they have extremely high pressure to make schedule and low incentive to work safely
