No stranger to the Clyde, having made an annual call at Greenock most years since she was built in 2002, the Maltese-registered cruiseship CELEBRITY CONSTELLATION was seen heading down the river from Ocean Terminal on Thursday afternoon, en route to Reykjavik. Originally named just CONSTELLATION, this 90,280 gross ton ship was built in France by Chantiers de l'Atlantique for Celebrity Cruises, and is the final member of their 'Millennium' class of four vessels. One of the first cruiseships to be fitted with azimuthing 'pod' propulsion, she takes her main power from two gas turbine power plants, although diesel machinery was added in 2007 in an attempt to reduce fuel consumption. In 2007 her owner's title was prefixed to her original name while at the same time, her port of registry was changed from Nassau to Valletta - until 2003 she had flown the Liberian flag. CELEBRITY CONSTELLATION can accommodate a maximum of 2,034 passengers, and is 294.0 metres long. She is rated with five stars in many cruiseship guidebooks.
