Sirena, formerly R Four, Tahitian Princess, and Ocean Princess is an R-class cruise ship formerly owned by Princess Cruises. Along with the Pacific Princess, the smallest in the Princess fleet, she mostly sails in Europe and to exotic destinations such as Asia, Africa, and the South Pacific. In March 2016, she was sold to Oceania Cruises and renamed Sirena.
History

The vessel entered operation in 1999 under the flag of Renaissance Cruises. The ship was not owned by the company; instead she was owned by a group of French investors. When Renaissance declared bankruptcy in 2001, the ship was seized by creditors, along with the other seven vessels in the fleet.

In 2002, Princess Cruises secured a two-year lease for R Four and her sister ship R Three (now Pacific Princess). The vessel entered operation at the end of 2002, and was renamed Tahitian Princess. At the end of the lease, Princess Cruises purchased both vessels.
In November 2009 the Tahitian Princess was renamed Ocean Princess to "reflect a more global theme."

It was announced on November 25, 2014, that the ship is to be sold to Oceania Cruises under a definitive agreement. The ship was sold for 82.000.000 $. She is expected to depart the Princess fleet in March 2016 when she will undergo a 35-day, $40 million refurbishment in Marseille, France to become Sirena. On April 27, 2016, The Sirena was christened and entered service for Oceana Cruises.
