Ocean Princess

(12:45 p.m. EST) -- Shortly following the official acquisition of Prestige Cruises International, Inc. (Oceania Cruises and Regent Seven Seas), Norwegian Cruise Holdings, Ltd. has purchased Princess Cruises' Ocean Princess with the intention to add it to the Oceania Cruises fleet under the name Sirena. The ship will join Oceania Cruises' R Class, along with fleetmates Insignia, Regatta and Nautica.

The 684-passenger Ocean Princess will be delivered in March 2016 and will undergo a 35-day, $40 million dry dock in Marseille. Using recently refurbished Insignia as inspiration, Ocean Princess will transform into Sirena with a number of touches including the addition of Toscana and Polo Grill, Baristas and Terrace Cafe.

"The addition of Sirena opens up an entire array of new itinerary options for Oceania Cruises as we think about our deployment strategy," said Kunal S. Kamlani, president and chief operating officer of Oceania Cruises, in a press release.

Sirena will set sail in late April 2016. Details about the ship's inaugural season will be released in late February 2015, and reservations will open March 4, 2015.
