The 225,000-ton luxury "floating islands" are each divided into seven "neighbourhoods" including a Central Park filled with more than 12,000 plants, and feature innovative two-deck loft suites, nearly 3,000 staterooms and around 20 dining options.
Oasis of the Seas set off on her maiden cruise at the beginning of December and her sister ship Allure will follow in late 2010.
As well as the glass, Pilkington Marine has supplied design and assembly services for a range of features including the roof and wall structures of the 15th deck Jacuzzi, the glass roof of the Solarium area above the bow and all of the panoramic window and windshield structures on the outer decks.
* Pilkington Marine has recently won a contract to supply panoramic glass walls, windshields and railings for two P&O passenger ferries to be built at STX Finland Cruise Ltd.
The ships are scheduled for delivery in 2010 and 2011 and the contract includes options for a further two vessels.
