The announcement on Wednesday could help the brand begin rebounding from a wave of bad publicity that began in February, when an engine fire knocked out power on the Carnival Triumph.
Passengers endured filthy conditions as the Triumph was towed to Mobile, Ala., resurrecting stories of a similar incident from 2010 aboard the Carnival Splendor. Cruise sellers say prices for Carnival cruises have dropped.
Carnival said the first phase of improvements involves installing an additional emergency generator on every ship. Carnival is also installing high-pressure upgraded water mist systems on all ships to improve fire safety.
