Celebrity Infinity

Overview

Celebrity Infinity is a Millennium-class cruise ship operated by Celebrity Cruises, part of Royal Caribbean Group. She was the second of four Millennium-class ships, following Celebrity Millennium, and she entered service in 2001 as simply Infinity, taking the Celebrity prefix later in her career. At 90,940 GT and 294 metres long, she was part of the generation that moved Celebrity from mid-sized ships into the 90,000-ton class while keeping passenger numbers comparatively restrained — her own article gives a capacity of 2,170 guests. Her historical importance is double-edged: the Millennium class introduced gas-turbine electric propulsion and podded drives to the premium market, but Infinity and her sisters also became the textbook case of early pod-propulsion unreliability, with repeated drydockings and a $300 million lawsuit that ran for most of a decade.

Key specifications

The dataset records 90,940 GT, a length of 294.0 m, a beam of 32.0 m and a speed of 24.5 kn; her article gives the beam as 32.2 m, a small variant that does not change the picture. She has 12 decks. Propulsion is the class-defining plant: a turbo-electric COGAS (combined gas and steam) installation in which two General Electric gas turbines are supplemented by a steam turbine driven from exhaust heat, recovering energy that would otherwise be lost and reducing specific fuel consumption. Electric power drives two Rolls-Royce/Alstom Mermaid azimuthing pod units, rated at about 19 MW each in her article's figures, supplemented by three bow thrusters. That plant gave the class a service speed around 24 knots — fast for a ship of her size and era — at the cost of the bearing problems described in section 7.

Design and construction

Royal Caribbean signed a letter of intent with the French builder Chantiers de l'Atlantique at Saint-Nazaire in February 1998 for the Millennium-class programme. Infinity was built as yard number S31. The class design paired a conventional, relatively narrow hull — a beam of about 32 m kept the ships within the limits of the locks then in use on the Panama Canal — with a radically new machinery arrangement: gas turbines high in the ship, electric transmission, and pods instead of shafts and rudders. She was floated out in June 2000 and delivered on 25 February 2001. Note that the dataset's "launched 2001" is her delivery/service year; her article dates the float-out to 9 June 2000, and that discrepancy is logged in the batch notes.

Naming, launch and maiden voyage

She entered service under the single-word name Infinity, in the style Celebrity then used for the class (Millennium, Summit, Constellation). She was sponsored by Solveig Wilhelmsen and christened on 29 April 2001, according to her article — after her maiden voyage, which took place on 3 March 2001. The Celebrity prefix was added in 2007, and she has sailed as Celebrity Infinity since then. Her registration history in the article runs from Monrovia, Liberia, at delivery, through Nassau, Bahamas, to Valletta, Malta, from 2008.

Career by operator

Infinity has had a single operator throughout her life: Celebrity Cruises. What changes across her career is not the brand but the ship's name form and her technical history.

Within that single-operator career, the defining operational story is the recurring failure of her Mermaid pod units (section 7), which repeatedly took her out of service in her first six years. Beyond that, hers has been a conventional premium-line career of long seasons in the major cruise regions, punctuated by scheduled drydock refreshes; the portfolio's evergreen rule means individual deployments are not catalogued here.

Onboard character

The Millennium class was Celebrity's statement of modern premium design at the turn of the century: a glass-heavy superstructure, exterior glass elevators and a restrained, contemporary interior style that contrasted with the themed decoration of contemporary mass-market ships. The COGAS plant was part of the character as well as the engineering — gas turbines produced less vibration and lower emissions than the diesel plants of rival ships, and the quiet, smooth ride was marketed as part of the premium experience. With about 2,170 guests on a 90,940 GT hull, she offered a notably generous space ratio for her era, a positioning the class was designed around.

Major refits and incidents

The dominant entry here is the pod saga. Months after delivery, a faulty ball bearing in the starboard propulsion unit forced an emergency drydocking at Victoria, British Columbia, in June 2001, with sailings cancelled. Further pod drydockings followed in April 2002 (premature bearing wear that limited her speed), February 2003 (all ball-bearing units replaced, two sailings cancelled), April 2004 (a thrust-bearing unit replaced), March 2005 (starboard thrust bearing replaced again) and September 2006 (a further pod repair). In August 2003 Royal Caribbean sued Rolls-Royce and Alstom for $300 million to recover lost revenue and repair costs across all four Millennium-class ships; the suit was settled in January 2010. The ships' later careers were far more settled, and Infinity has since undergone periodic drydock refurbishments in normal fleet rhythm.

Sister ships and class

The Millennium class comprises four ships, all built by Chantiers de l'Atlantique: Celebrity Millennium (2000, lead ship), Celebrity Infinity (2001), Celebrity Summit (2001) and Celebrity Constellation (2002). All four shared the COGAS-plus-Mermaid-pod machinery arrangement and its early troubles, and all four remain associated with Celebrity. The class was succeeded in Celebrity's fleet by the larger Solstice class from 2008.

Fate and where she is now

There is no fate to record yet: Celebrity Infinity remains an active Celebrity Cruises ship, flagged in Malta, more than two decades after delivery — a longer front-line career than her troubled first years suggested. Her dataset status is "active — operating," originally as Infinity.
