Celebrity Constellation by Celebrity

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/Alstom MerMaid azimuth 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.
