MS Oasis of the Seas is an Oasis-class cruise ship, delivered to its owner, Royal Caribbean International, in October 2009. The first of her class, she was joined by her sister ship MS 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 surpassed the Freedom-class cruise ships (also owned by Royal Caribbean) to become the largest cruise ship in the world at that time. She has, however, since been surpassed by Allure of the Seas, which is 50 millimetres (2.0 in) longer, although this difference may have been caused by different temperatures when the measurements were made.
The vessel was ordered in February 2006 and designed under the name "Project Genesis". Her keel was laid down on 12 November 2007 at STX Europe - a subsidiary of the South Korean industrial chaebol STX Corporation - (formerly Aker Yards) in Turku, Finland. The company announced that full funding for Oasis of the Seas was secured on 15 April 2009.
The name Oasis of the Seas resulted from a competition held in May 2008.
During the first float-out of the vessel the tugboats that were pulling the ship from its dock failed to control the ship, resulting in the port side of the ship colliding with the dock. This resulted in some cosmetic damage and minor damage to the hull, which was repaired and did not affect the final delivery date of the vessel.
The ship was completed and turned over to Royal Caribbean on 28 October 2009. Two days later, she departed Finland for the United States. While exiting the Baltic Sea, the vessel passed underneath the Great Belt Fixed Link in Denmark on 1 November 2009. The bridge has a clearance of 65 m (213 ft) above the water; Oasis normally has an air draft of 72 m (236 ft). The passage under the bridge was possible due to retraction of the telescoping funnels, and an additional 30 cm (12 in) was gained by the squat effect whereby vessels traveling at speed in a shallow channel will be drawn deeper into the water. Approaching the bridge at 20 knots (37 km/h; 23 mph), the ship passed under it with less than 2 feet (60 cm) of clearance.
Proceeding through the English Channel, Oasis stopped briefly in the Solent so that 300 shipyard workers who were on board doing finishing work could disembark, then left on the way to her intended home port of Port Everglades in Fort Lauderdale, Florida. The ship arrived there on 13 November 2009, where tropical plants were installed prior to some introductory trips and her maiden voyage on 5 December 2009.
While Royal Caribbean's chief of captains William S. Wright was in command of the ship's journey across the Atlantic and also for the first few sailings, navigation of the Oasis of the Seas is regularly handled by Trym Selvag and Thore Thorolvsen. The ship was featured in an episode of the third season of Mighty Ships, a production of Discovery Channel Canada which aired during the spring of 2011.
Oasis had a minor refit in winter 2011, adding the DreamWorks Experience which allows passengers to interact with characters, such as Shrek, on board the ship. The Oasis class also now features 3D movies.
In April 2012, the Oasis rescued a group of Cuban refugees adrift in the Caribbean Sea. After contacting the coast guard the crew gave them food and water, but after determining that their boat was in immediate danger of sinking decided to bring them aboard. The refugees were dropped off the following day in Cozumel, being handed over to Mexican authorities.
Oasis is scheduled to enter drydock in Spring 2014.
Technical details 
The gross tonnage of the Oasis of the Seas is 225,282. Her displacement—the actual mass of the vessel—is estimated at approximately 100,000 metric tons (110,000 short tons), slightly less than that of an American Nimitz-class aircraft carrier.
To keep the ship stable without increasing the draft excessively, the designers created a wide hull. 9.3 metres (31 ft) of the ship sits beneath the water, a small percentage of the ship's overall height. Wide, shallow ships such as this tend to be "snappy", meaning that they can snap back upright after a wave has passed, which can be uncomfortable. This effect, however, is mitigated by the vessel's large size. The cruise ship's officers were pleased with the ship's stability and performance during the transatlantic crossing, when the vessel, in order to allow finishing work to go on, slowed and changed course in the face of winds "almost up to hurricane force" and seas in excess of 12 metres (39 ft).
While the design length of the Allure of the Seas is the same as that of her sister, she is actually about 50 millimetres (2.0 in) longer than the Oasis of the Seas. According to the shipyard, this is not intentional and such small differences in length may occur simply due to the temperature of the steel in such a large ship.
The ship's power comes from six medium speed marine diesel generating sets: three 16-cylinder Wärtsilä 16V46D common rail engines producing 18,860 kilowatts (25,290 hp) each and three similar 12-cylinder Wärtsilä 12V46 engines producing 13,860 kilowatts (18,590 hp) each. The fuel consumption of the main engines at full power is 1,377 US gallons (5,210 l; 1,147 imp gal) of fuel oil per engine per hour for the 16-cylinder engines and 1,033 US gallons (3,910 l; 860 imp gal) per engine per hour for the 12-cylinder engines. 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 electric 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) transverse bow thrusters.
The ship carries 18 lifeboats that hold 370 people each, for a total of 6,660 people. Inflatable life rafts provide for additional passengers and crew.
Oasis of the Seas offers passengers features such as two-story loft suites and luxury suites measuring 1,600 sq ft (150 m2) with balconies overlooking the sea or promenades. The ship features a zip-line, a casino, a miniature golf course, multiple night clubs, several bars and lounges, a karaoke club, comedy club, five swimming pools, volleyball and basketball courts, theme parks and nurseries for children. Many of the ship's interiors were extensively decorated by muralist Clarissa Parish.

Naming ceremony and launch party 
The ship was formally named on 30 November 2009 during a charity sailing for Make-A-Wish Foundation. At this ceremony the ship was sponsored by seven "godmothers", each representing one of the seven neighbourhoods on board. The godmothers were Gloria Estefan, Michelle Kwan, Dara Torres, Keshia Knight Pulliam, Shawn Johnson, Jane Seymour and Daisy Fuentes.
On 1 December 2009, a four-night pre-inaugural sailing began from Port Everglades, Fort Lauderdale, Florida, calling at Labadee in Haiti (3 December) and returning to Port Everglades, before the ship left Port Everglades, Fort Lauderdale, Florida, on 5 December 2009 on its maiden voyage, calling at (8 December) St. Thomas, (9 December) St. Maarten, and (11 December) Nassau.
