Cruise Carnival Triumph returns to Galveston By Jerry Limone / June 12, 2013 Share 1 -- Four months after an engine-room fire knocked the ship out of commission, the Carnival Triumph is set to return to service on June 13.The 2,758-passenger ship is back in Galveston and will resume operating four- and five-day Mexico cruises year-round from the Texas port. The ship underwent $115 million in upgrades during a drydock in the Bahamas. Carnival said it has improved the ship’s fire-suppression system and has installed a second backup generator, so that key hotel operations (toilets, elevators and food service) can continue to function in the event that the main power is knocked out.The engine-room fire in February left the ship without power for five days at sea, leaving passengers with limited hot food, no air conditioning and nonfunctioning toilets. Carnival also added restaurants and bars that were introduced on the Carnival Breeze last year. These include Guy’s Burger Joint, Blue Iguana Cantina, RedFrog Rum Bar, Alchemy Bar and EA Sports Bar.The Triumph’s June 13 sailing from Galveston is sold out, according to Carnival.
