Has a carnival cruise line ship ever sunk?

A Carnival Cruise Line ship has never sunk but there have been some notable mishaps. On the maiden voyage of the only ship in the "Golden Fleet", the "Mardi Gras" ran aground and was delayed. Shortly thereafter, the ship's slot machines were raided to get money to buy fuel so the ship could continue its cruise. In 1989 the "Celebration" collided with a disabled Cuban cement hauling freighter, slicing it in half, with loss of three lives. The Celebration returned to port with bow damage. There have been several other incidents involving "bumps" into other ships (e.g. - Royal Caribbean "Enchantment of the Seas in 2009) and docks (e.g. - St. Kitts in January 2010) but a ship bearing Carnival's name has never sunk.
