Carnival Cruise Line said its ship operating out of San Juan, the Carnival Fascination, will be chartered to the Federal Emergency Management Agency (FEMA), wiping out four months of cruises.

The move came at FEMA’s request, Carnival said. The cruise line had been set to resume its normal seven-day cruise schedule from San Juan on the Carnival Fascination on Oct. 15.

Instead, Carnival said departures from Oct. 15 through Jan. 28 have been canceled. The Fascination will resume regular year-round cruising from San Juan on Feb. 18.

“We recognize how important vacations are, and we sincerely apologize for the disruption this late change in plans has caused our guests and travel partners,” a Carnival advisory said. “We value your trust in us and hope you understand that this decision was made after careful consideration of the great need to support the recovery efforts in the region.”

Carnival also modified Caribbean itineraries on a variety of ships through Dec. 31 that substitute new ports of call for visits that had been scheduled for St. Maarten and St. Thomas.

Carnival joins Bahamas Paradise Cruise Line in chartering a ship to FEMA for hurricane relief efforts in the U.S. Virgin Islands.

In 2005, Carnival chartered three of its ships to FEMA for six months for emergency housing in New Orleans after Hurricane Katrina.
