The senator got into more detail in a letter to Carnival CEO Micky Arison (pdf), noting that the US Coast Guard and the US Navy report that the costs of responding to the 2010 Carnival Splendor incident were $1,541,904.53 and $1,884,376.75, respectively. The Coast Guard tallied its costs in the Triumph fiasco at $779,914.26. “Given that you reportedly pay little or nothing in federal taxes, do you intend to reimburse the Coast Guard and the Navy for the cost of responding to either the Carnival Splendor marine casualty or the Carnival Triumph marine casualty?” wrote Rockefeller.

Rockefeller attached a list (pdf) from the US Coast Guard tracking Cruise Ship investigations since 2008. Here’s a segment of the list from February 2012, minus the latest incidents, with the Carnival incidents highlighted in yellow. (Princess Cruise Lines and Holland America Lines, or HAL, are also Carnival brands.)

That’s quite a track record. “”It’s the consequence of not being regulated under a true safety administration of any kind,” Walker says. Some attribute the unusual spate of incidents to management problems at Carnival.

A representative for the company cautions against over-generalizing. ”Each of these situations was different,” Vance Gulliksen, Senior PR manager at Carnival, told Quartz. “All modes of transportation, including cruise ships, have strong overall safety records but sometimes technical issues such as the one Carnival Dream is experiencing will occur from time to time.”
