The Dali’s blackout was a rare event. Could dirty fuel be to blame?

A total power and propulsion failure like the one the cargo ship Dali experienced before it struck and toppled the Francis Scott Key Bridge is an extremely rare occurrence, one possibly caused by either faulty equipment or contaminated fuel, maritime engineers and experts said. After the power failed, the ship coasted in the darkness before the generators and engine appeared to kick back on and its lights flickered before going dark again.
