Apparently there was an explosion onboard Cunard’s flagship in September. One of the ships electric generators blew a capacitor which caused oil to be sprayed onto high voltage wires. This caused an arcing event that caused the vessel to loose power momentarily. The damage was apparently severe not only to the generator but to surrounding areas and the control room. According to a recently released report from British Officials:
Also caused serious damage to an adjoining steel door into the main switchboard room, the stiffeners on the bulkhead of the compartment were buckled, and the steel cover plate on a cross-flooding duct was blown out into the main switchboard room.
No one was injured as they weren’t in the area at the time, and passengers hardly noticed anything. This report that was just released, was the first anyone has heard about such an event on board the Queen.
