Oasis of the Seas

Oasis of the Seas is a large cruise ship operated by Royal Caribbean International, a cruise brand within Royal Caribbean Group. It is the first vessel in the Oasis class, a ship family developed to combine the scale of a resort with the mobility and itinerary flexibility of an ocean-going cruise ship. When completed, it established a new benchmark for passenger capacity and briefly became the largest passenger ship in the world, surpassing Royal Caribbean's earlier Freedom-class ships. It was subsequently exceeded in size by other Oasis-class vessels, including Allure of the Seas, Harmony of the Seas and Symphony of the Seas, and later by ships in Royal Caribbean's Icon class. The vessel originated as Project Genesis. Royal Caribbean ordered the ship in February 2006, and its keel was laid at STX Europe's Turku Shipyard in Finland on 12 November 2007. The name Oasis of the Seas was selected through a public competition in 2008. Construction and finishing work were completed in 2009, and the ship was formally delivered to Royal Caribbean on 28 October of that year. During its transfer from Finland to the United States, the ship passed beneath Denmark's Great Belt Fixed Link with its telescoping funnels retracted and arrived at Port Everglades in Fort Lauderdale on 13 November 2009. Its maiden voyage began on 5 December 2009. At launch, Oasis of the Seas had gross tonnage of approximately 225,282 and capacity for as many as 6,669 passengers, making it a landmark in contemporary cruise-ship design. Its layout is organized around several themed neighborhoods rather than a single continuous interior. Major spaces include the open-air Central Park and Boardwalk areas, an AquaTheater, entertainment venues, pools, restaurants, bars, youth facilities and sports areas. Attractions include a zip line, an ice-skating rink, a FlowRider surf simulator, water slides, a casino, miniature golf, nightlife venues and the Ultimate Abyss dry slide. This combination of accommodation, dining, entertainment and large-scale attractions positions the ship as a floating resort aimed at families, couples and multigenerational groups. The ship is powered by six Wärtsilä marine-diesel generator sets that produce electricity for hotel systems and propulsion. Three ABB Azipod electric propulsion units and bow thrusters provide maneuverability. Solar panels installed on an upper deck supply electricity for lighting in selected public areas. The vessel also carries 18 lifeboats, each designed for 370 people, together with additional inflatable life rafts. Oasis of the Seas has undergone several rounds of maintenance and modernization. A minor refit took place in 2011, followed by a larger drydock refit in October 2014, during which the main dining room was divided into three restaurants. After a Mediterranean deployment in 2019, the ship underwent an extensive drydock program lasting almost three months. The work added or refreshed amenities and increased gross tonnage to approximately 226,838 through the addition of cabins on Deck 14. The ship was then repositioned to Miami for the following season and was scheduled to become the first Oasis-class vessel homeported at Cape Liberty in New Jersey in 2020. Pandemic-related operational disruptions changed those plans. By late 2024, the ship was operating Caribbean cruises from Port Everglades and Cape Liberty, with Port Everglades again serving as a home port after its return from a Mediterranean season.

Oasis of the Seas was developed as Project Genesis, Royal Caribbean's effort to create a new class of cruise ships substantially larger and more spatially differentiated than its Freedom-class predecessors. The vessel was ordered in February 2006 and constructed at STX Europe's Turku Shipyard in Finland. Its keel was laid on 12 November 2007. The ship's name was selected through a competition held in May 2008, reflecting the vessel's resort-like concept and its extensive open-air public spaces. During construction, a tugboat incident at the first float-out caused the port side to contact the dock. The damage was described as cosmetic and minor, was repaired, and did not delay delivery. Royal Caribbean announced in April 2009 that full funding for the project had been secured. The completed ship was delivered on 28 October 2009 and departed Finland for the United States two days later. The transfer voyage attracted attention because of the ship's passage beneath Denmark's Great Belt Fixed Link on 31 October 2009. Oasis of the Seas normally had an air draft greater than the bridge's clearance, but retractable funnels, the vessel's speed and the squat effect reduced the effective height sufficiently for the passage, which occurred with very limited clearance. After a brief stop in the Solent to allow shipyard workers to leave, the ship continued to Port Everglades, arriving on 13 November 2009. Tropical plants and other final preparations were installed before introductory cruises and the maiden voyage on 5 December. Oasis of the Seas entered service as the first Oasis-class ship and briefly held the title of the world's largest passenger ship. Its launch gross tonnage was approximately 225,282, and it could carry up to 6,669 passengers. The design divided the ship into neighborhood-style zones, including Central Park and Boardwalk, enabling the vessel to offer multiple atmospheres and circulation areas rather than one undifferentiated interior. Its facilities included an AquaTheater, pools, waterslides, sports courts, a zip line, an ice rink, a surf simulator, a casino, children's areas, nightclubs and numerous restaurants and lounges. The ship received a minor refit in winter 2011. A second drydock in October 2014 changed the main dining room into three restaurants. In 2019, after a Mediterranean deployment, it spent almost three months in drydock receiving new and upgraded amenities. Cabins added on Deck 14 increased gross tonnage to about 226,838. The vessel then moved to Miami for fall and winter operations and was planned for Cape Liberty in New Jersey in 2020. The global COVID-19 crisis interrupted those plans. During a March 2020 sailing, Royal Caribbean reported a possible infection to U.S. health authorities, passengers disembarked in Miami, and the company suspended sailings. Crew infections and deaths followed during the ship's layup. Oasis of the Seas later returned to cruise operations, continuing the broader Royal Caribbean strategy of deploying large ships on Caribbean and Mediterranean itineraries. By November 2024, it had returned to Port Everglades and was operating Caribbean cruises from that port as well as from Cape Liberty.

  The sole vessel represented by the Oasis of the Seas name. It sells cruise vacations rather than a standalone consumer product, providing cabins, restaurants, bars, pools, entertainment, sports, children's facilities and organized shore itineraries. Its neighborhood layout, Central Park, Boardwalk and AquaTheater distinguish it from smaller conventional cruise ships, while attractions such as the zip line, FlowRider, waterslides and Ultimate Abyss support the ship's floating-resort positioning.
