She was built at the Chantiers de l'Atlantique shipyard in St. Nazaire, France. The ship is powered by a COGES[3] power plant of gas turbines and a steam turbine providing up to 60 megawatts for the electric systems and two 19 MW Rolls-Royce/AlstomMerMaidazimuth thrusters for propulsion. In 2007, an additional diesel engine was fitted as a fuel-saving measure.[4] The ship can run on any combination of the gas turbines or diesel. In port, she generates electrical power from the diesel.
During the summer period the ship sails to the Mediterranean, repositioning to the Caribbean in the winter months.
Celebrity Constellation was scheduled to complete an extensive renovation in May 2020.[5] However, as a result of the business impact from the Covid-19 pandemic, these plans are delayed until a future unannounced date. Another rumor that Celebrity Constellation and sister ship Celebrity Infinity are to be sold or leased to Spanish cruise line, Pulmantur, has been denied[6] by Celebrity Cruises.
In mid-2021, Celebrity Constellation was supposed to receive a multi-million dollar refit, but it was postponed until Spring 2024.
Routes
Celebrity Constellation has operated in the Mediterranean and Adriatic during the summer seasons and in the Persian Gulf during the rest of the calendar year. In October 2020, she repositioned to Tampa, Florida to operate Caribbean and Panama Canal voyages, marking Celebrity's return to Tampa after a 13-year absence.[7]
