Doesn’t look like an engine fire in that picture.
The Coast Guard says the motor caught fire on the ship. The Coast Guard as well as the Port of Houston and the Houston Fire Department is working to put the fire out.

Fire crews worked to extinguish flames seen on the deck of the Navigator Europa docked at the Port of Houston.
Sorry. That picture was in the article, but I’ve realized it is a file photo of ship fire and not of the actual event.
