Cahill said some of those lessons learned after Splendor proved valuable in responding to the Triumph fire. Last week, he would not say if the same cabling problem was responsible for disabling power on the Splendor or how many other ships in the fleet might have the same issue. But in 2011, when the Splendor was returning to service, the company told media outlets that the power outage was the result of fire-damaged cabling.

This month, new questions have emerged after three different ships reported technical issues: the Carnival Dream, which had to fly passengers home from St. Maarten after a routine test revealed a failure in a backup generator; the Carnival Elation, which was struck with a steering problem and the Carnival Legend, which had propulsion issues.

The announcement Tuesday did not address mechanical problems. In a statement over the weekend referring to the most recent trio of issues, the company said: “We are committed to learning from any incident that may occur on one of our vessels to apply lessons learned and prevent future occurrences.”

The Miami-based company’s rash of bad news has taken a toll. Carnival Corp. last week lowered earnings estimates for the rest of the year, saying discounting is pushing revenues down and repairs will drive costs up. The preliminary price tag for repairs related to the review this year is $40 million. Costs related to the Triumph — including repairs and loss of revenue — are expected to reach $80 million.

The company’s stock price has dropped more than 12 percent since Feb. 8, the last day of trading before the Triumph fire. Shares closed Tuesday at $33.21, down more than two percent from the previous day.
