Royal Caribbean's third Oasis-class ship will be built at STX France shipyard and today ArcelorMittal has been selected to provide 100% of the steel for the hull and 20 bridges in the new ship.
The agreement will supply more than 40,000 tonnes of plates and coils from ArcelorMittal's European sites.
The coils will be produced at Fos-sur-Mer, France and will then be processed into sheets by ArcelorMittal's St Nazaire Distribution Solutions unit. Afterwards, the coils will then be delivered to STX France.
The plates are being produced by ArcelorMittal Gijon, Spain and shipped to STX France.
Deliveries will commence in September 2013, when construction of the hull will begin.
Hervé Bourrier, CEO, ArcelorMittal France said: "This contract demonstrates our ability to deliver high quality steels and tailored services from our European industrial and sales units, and confirms our long-term presence as a steel supplier to the cruise ship market, one that has seen consistent growth over the last five years."
The ship, which will have around 2,700 cabins, will be delivered in 2016 to Royal Caribbean.
