The GTS Celebrity Millennium is a notable Millennium-class cruise ship operated by Celebrity Cruises, a subsidiary of Royal Caribbean Group. Delivered in 2000, she is the oldest vessel still active in Celebrity’s fleet and serves as the class’s flagship. Constructed by Chantiers de l'Atlantique, she was the first new-build for Celebrity following its merger with Royal Caribbean, and notably the first not built by Meyer Werft. Her launch date was November 7, 1999, with sea trials beginning in April 2000, and she was christened in Southampton on June 26, 2000. The vessel measures approximately 91,000 gross tons and features a length of around 294 meters. She is powered by advanced gas turbines integrated into a turbo-electric COGES power plant, which was innovative at the time, utilizing waste heat from gas turbines to generate steam and improve fuel efficiency. Propulsion is achieved through two azimuth pod-propulsion units supplied by Kamewa and Cegelec (now Alstom). Her original hull livery was predominantly dark blue with yellow and white bands. The Millennium’s interior includes unique features such as the Olympic Restaurant, which contains walnut wood panels originally used on the RMS Olympic. Over her service life, she has undergone refurbishments, including a significant 35-day dry dock in Singapore in early 2019, adding 30 new passenger cabins. Her service history is extensive, including deployments in Europe, the Caribbean, Australasia, and Alaska. She has experienced notable incidents, such as a passenger jumping overboard in 2011 and damage from striking a submerged rock in 2007, which caused cancellations and repairs. The ship also encountered electrical issues with her pod-propulsion motors in 2013, resulting in significant operational disruptions and financial costs. Despite these challenges, she remains a key vessel within Celebrity Cruises, representing technological innovation with her gas turbine propulsion and her longevity in service.
