Vehicles laden with fuel in a ship's hold require very specific and meticulous procedures to prevent accidents.
Well I guess this answers my question:
“Captain Joao Mendes Cabeças of the port of Hortas told Reuters that special equipment is needed to extinguish the blaze as lithium-ion car batteries in electric cars on board have caught fire. It is unclear whether the batteries caused the fire or if they were lit ablaze after something else caught fire, Cabeças said. It will either be towed to the Bahamas or a European country.”
