(CNN) Investigators know roughly where the flames erupted in the engine room of the Carnival Triumph, but it could be a year before they learn what caused the fire, which left the massive ship adrift for days in the Gulf of Mexico.
“We know that the fire originated in front of a generator,” Patrick Cuty, a senior marine investigator for the U.S. Coast Guard, told CNN Sunday.
“You can see the ignition marks on the wall.”
There are three generators in the engine room where the fire broke out. Three other generators are in a second engine room that wasn’t involved in the fire, Cuty said.
The same ship encountered a problem in January with its propulsion system, according to a notice posted on the website of Carnival senior cruise director John Heald.
“We’ll know by end of the next week whether the generator is the same one that was having an issue, an anomaly, in January, according to passengers we interviewed from previous cruises,” Cuty said.
