The Oasis class is a class of Royal Caribbean International cruise ships. The first two ships in the class, Oasis of the Seas and Allure of the Seas, were delivered respectively in 2009 and 2010 by STX Europe Turku Shipyard, Finland. A third Oasis class vessel, Harmony of the Seas, was delivered in 2016 built by STX France, and a fourth vessel, Symphony of the Seas, was completed in March 2018. Two additional unnamed ships are currently under construction and are expected to be delivered in 2021 and 2023 respectively; the first two ships in the class Oasis of the Seas and Allure of the Seas are slightly exceeded in size by the third ship Harmony of the Seas, while the Symphony of the Seas is the world's largest cruise ship. The fifth ship, due to be completed in Spring 2021, is planned to be larger than the Symphony of the Seas; as of early 2019, all ships of the class rank as the world's largest passenger ships.
The Oasis-class ships surpassed the earlier Freedom-class ships as the world's largest and longest passenger ships. Oasis also is 8.5 metres (28 ft) wider, and with a gross tonnage of 225,282, is around 70,000 tonnes larger. Oasis-class vessels can carry over 5,400 passengers.
Oasis-class ships feature a split structure, with the 5-deck high "Central Park" and "Boardwalk" outdoor areas running down the middle of the ship; these areas feature tropical gardens, restaurants, shops, and a working carousel.
To keep the ship stable without increasing the draft excessively, the designers created a wide hull. About 30 feet (9 m) 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 class' 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 40 feet (12 m).
The ship's power comes from six medium-speed, marine-diesel generating sets: three 16-cylinder Wärtsilä 16V46D common rail engines producing 18,480 kilowatts (24,780 hp) each and three similar 12-cylinder Wärtsilä 12V46D 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, the first vessel of the class, was ordered in February 2006 and designed under the name "Project Genesis", her keel was laid down on 11 December 2007 by STX Europe Turku Shipyard, Finland. The name Oasis of the Seas resulted from a competition held in May 2008, and full funding for Oasis of the Seas was secured in April 2009; 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 31 October 2009 at 23:18 UTC; 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 23 knots (43 km/h; 26 mph), the ship passed under it with less than 60 centimetres (2 ft) 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.
The keel of the second ship, Allure of the Seas, was laid on 2 December 2008 at the STX Europe Turku shipyard, Finland, during a ceremony involving Royal Caribbean and STX representatives, she was launched on 20 November 2009, with further outfitting taking place while afloat in the shipyard. Allure of the Seas was declared complete and formally delivered to Royal Caribbean on 28 October 2010, she left the Turku shipyard on 29 October 2010 at 05:45 UTC, heading directly to her home port of Port Everglades, near Fort Lauderdale, Florida, USA. The ship is equipped with telescoping funnels to pass under bridges such as the Storebælt Bridge, which she passed on 30 October 2010. While media has reported that there was only 30 centimetres (12 in) of clearance, the truth is that at the mean water level it was closer to 2–3 metres (6.6–9.8 ft) and the much-advertised squat effect, whereby vessels traveling at speed in a shallow channel will be drawn deeper into the water, did not have significant effect on the draft of the vessel.
Royal Caribbean confirmed on 25 October 2012 that they were engaged in negotiations to build the third Oasis-class ship, which would become Harmony of the Seas; the ship was officially ordered from STX France on 27 December 2012, after failing to come to an agreement with the Government of Finland for additional financial support to build the ship at the STX Finland shipyard that built the first two ships. Steel cutting began on 23 September 2013, and the ship was delivered in May 2016; the ship is larger than the preceding Oasis-class ships at an estimated 227,700 GT, 362.15 m in length, and 66 m in maximum width, representing an increase of 2,418 GT and 2.15 m length. The ship has 2,744 passenger staterooms with a capacity of 6,360 passengers (5,488 double occupancy), an increase of 64 passengers over the previous ships in the class, as well as 1,197 crew cabins capable of berthing 2,100 crew; the ship features an expanded adults-only solarium area and a water slide. It cost about €1 billion (US$1.35 billion) and entered service in May 2016.
In May 2014, Royal Caribbean exercised their option for a fourth Oasis-class ship, which would become Symphony of the Seas Steel cutting began in February 2015 had begun for the fourth ship, and the name of the ship was announced in March 2017; the ship was delivered in April 2018.
In May 2016, Royal Caribbean signed an agreement for a fifth Oasis-class ship, later named Wonder of the Seas. Steel cutting began on 24 April 2019, and the keel was layed in October of that year; the ship name was announced on 10 October 2019, and the ship is planned to enter service in the spring of 2021, based in the Chinese market.
In February 2019, Royal Caribbean Cruises Ltd. ordered a sixth Oasis-class ship, which is planned to be the largest in the world when she enters service.
