All of our theories and speculation are fun, but I would bet on much more simple and common mechanical failure. There is one thing that I would bet will be looked at by the investigating agencies...did the Dali take on fuel while in Baltimore? Of course we have no way of knowing, but there are many grades of marine diesel (Not like your diesel, it's a blend of diesel #2 and heavy fuel oil))...and moneywise of course, the owners buy the lowest grades and prices. It's up to the ships engineers to make the fuel work, by filtering, settling and or centrifuging. It's nasty stuff, often containing the dregs of the refinery or at least sediments from the bottoms of dirty storage tanks. Fuel contamination for a dollar Alex.
I've heard this a lot too - fuel explains the loss of power/mechanical failure that some people just are completely unable to understand DOES happen without a "cyber attack", while simultaneously bemoaning how expensive it is to fix their Ford in the driveway and Mercury OB on the bass boat. Never making the connection.
