In brief
Oasis of the Seas is a cruise ship operated by Royal Caribbean International. She is the first of the Oasis class whose ships were the largest passenger ships in the world, until surpassed in 2024 by the Icon class. Her hull was laid down in November 2007 and she was completed and delivered to Royal Caribbean in October 2009. At the time of construction, Oasis of the Seas set a new capacity record of carrying 6,669 passengers. She was joined by sister ships Allure of the Seas in December 2010, Harmony of the Seas in May 2016, Symphony of the Seas in April 2018, and Wonder of the Seas in March 2022, as well as Utopia of the Seas in July 2024. As of November 2024, Oasis of the Seas conducts cruises in the Caribbean from her home port of Port Everglades in Fort Lauderdale, Florida, as well as Cape Liberty (Bayonne), New Jersey
Oasis of the Seas surpassed the Freedom-class cruise ships (also owned by Royal Caribbean) to become the largest cruise ship in the world at that time. Later, Oasis of the Seas was surpassed by Allure of the Seas by 50 millimetres (2.0 in).

In context
Every figure in this section is a count, a rank or a percentile over vessels actually held in this registry — not over the world fleet, which is larger. Nothing here is estimated.
At 226,838 gross tons, Oasis of the Seas is the 77th largest of the 84,014 vessels in this registry that report a tonnage. The median across that set is 5,994 GT, so this hull is about 38 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 665 cruise ships held here, it ranks 9th by tonnage — larger than 98% of that group. Their median tonnage is 43,009 GT, and the largest tenth begin at 143,289 GT. The flag most often flown by this group is The Bahamas (133 ships). The yard that appears most often against it is Fincantieri, with 112 hulls on record.
The Bahamas is the country of registry for 1,614 vessels in this directory, of which Oasis of the Seas is the 9th largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (940 ships), and the median vessel measures 30,020 GT. Browse every ship flagged The Bahamas.
Narrowing to both dimensions at once, this registry holds 133 cruise ships flying the The Bahamas flag, of which 8 are larger by tonnage.
Oasis of the Seas was built in 2009, making it 17 years old. It is one of 2,834 hulls in this registry delivered that year, a cohort whose median tonnage is 11,673 GT; within it this ship is the 1st largest. Across the whole of the 2000s the registry holds 18,605 vessels, median 9,957 GT. The median build year across the entire registry is 1995.
The registry attributes 37 vessels to STX Finland, with a median tonnage of 5,077 GT, delivered between 1956 and 2015. See the rest of that yard’s output.
At 360.0 m overall, Oasis of the Seas is 161.9 m longer than the 198.1 m median for cruise ships on record, with a beam of 60.5 m and a draft of 9.3 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9383936 this registry holds 75 other vessels, whose median build year is 2008 and which range from 2006 to 2011. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2009.
Its IMO number, 9383936, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 3×6 + 8×5 + 3×4 + 9×3 + 3×2 = 166 — and the last digit of that total, 6, must equal the seventh digit, 6. It does, so this number is well formed.
