Sirena, formerly R Four,
Tahitian Princess, and Ocean Princess is an R-class cruise ship formerly
owned by Princess Cruises. When part of the Princess fleet, along with
the Pacific Princess, Ocean Princess was one of the two smallest in the
fleet. In March 2016, she was sold to Oceania Cruises and renamed Sirena.
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 25 November 2014, that the ship was to be sold to
Oceania Cruises for $82 million under a finance agreement. She departed
the Princess fleet in March 2016 and underwent a 35-day, $40 million
refurbishment in Marseille, France to become Sirena. On 27 April 2016,
The Sirena was christened and entered service for Oceania.
MS Sirena is scheduled to undergo a significant renovation in May 2019
as a part of the company's $100 million OceaniaNEXT program.
