Oasis of the Seas is an Oasis-class cruise ship in the fleet of Royal Caribbean International. The first of her class, she was joined by her sister ship Allure of the Seas in December 2010. Both vessels cruise the Caribbean from Port Everglades in Fort Lauderdale, Florida. She set a new record of carrying over 6,000 passengers.
The ship surpasses the Freedom-class cruise ships (also owned by Royal Caribbean) as the largest cruise ship in the world.
Some interesting data
Mass of the vessel is 100,000 tons
The ship's power comes from six marine diesel engines, three Wärtsilä 16-cylinder common rail diesels producing 18,860 kilowatts (25,290 hp) each (consuming 1,377 gallons of fuel per hour of operation per engine), and three similar 12-cylinder engines each producing 13,860 kilowatts (18,590 hp), (consuming 1,033 gallons of fuel per hour of operation per engine).
The total output of these prime movers, some 97,020 kilowatts (130,110 hp), is converted to electricity, used in hotel power for operation of the lights, elevators, electronics, galleys, water treatment plant, and all of the other systems used on the operation of the vessel, as well as propulsion.
Propulsion is provided by three 20,000-kilowatt (26,800 hp) "Azipods", ABB's brand of azimuth thrusters. These pods, suspended under the stern, contain electric motors driving 20-foot (6 m) propellers. Because they are rotatable, no rudders are needed to steer the ship. Docking is assisted by four 5,500-kilowatt (7,380 hp) bow thrusters in tunnels.
