Construction
On 6 September 2016, Finnish shipbuilder Meyer Turku announced it had signed a memorandum of agreement with Carnival Corporation & plc to build two ships for Carnival Cruise Line, with deliveries expected in 2020 and 2022, respectively.[8] The ships would be powered by liquefied natural gas (LNG),[8] making them the first LNG-powered ships to be based in North America.[9] Carnival explained that the company's pivot towards LNG was due in part to the demands voiced by environmental groups and the European Union to reduce greenhouse gases and other emissions.[10] In order to fulfill the order, Meyer Turku postponed the delivery of sister brand Costa Cruises' second Excellence-class vessel by one year to 2021.[8]
On 15 November 2018, Carnival held the steel-cutting ceremony for the ship at Meyer Turku.[9] Carnival also unveiled the new ship's livery, which features a predominantly blue hull with red and white accents.[9] The new style marked a departure from the fleet's mostly white hulls and was commissioned by Carnival in an effort to market the brand as "America's Cruise Line."[9] On the 5 December 2018 episode of American game show Wheel of Fortune, hosts Pat Sajak and Vanna White initially revealed the name of the ship as Carnival Mardi Gras, after Carnival's first ship, TSS Mardi Gras, which operated for Carnival from 1972 to 1993.[11][12] Prior to the reveal, leaked renderings of a ship bearing the name Carnival Reflection fueled speculation that Carnival's next ship would be named as such.[12] After the reveal, Carnival issued a press release clarifying the ship's name as simply Mardi Gras.
In May 2019, a floating engine room unit built at Neptun Werft in Rostock headed for Turku.[14] On 18 June 2019, the ship's keel was laid at Meyer Turku with the traditional coin ceremony, in which a coin was set atop the ship's keel blocks.[15] On 24 January 2020, Mardi Gras was floated out and repositioned elsewhere in the shipyard to complete her outfitting.[16] In March 2020, a fire contained to a cabin broke out during final outfitting work; no further damage was reported.[17] On 28 September 2020, the ship set sail for her first set of sea trials for 10 days from Airisto.[18]
Compounded by the impact of the COVID-19 pandemic, Mardi Gras's delivery was affected by construction delays at Meyer Turku, joining sister ships AIDAnova and Costa Smeralda in having experienced similar delays by her shipbuilder's parent company Meyer Werft. Most of the delays affecting all vessels were blamed on the complexities associated with building and installing the ships' new technologies, as well as organizing the logistics of the ships' construction.[19] After first postponing the delivery to October 2020,[20] Meyer Turku delivered the ship to Carnival on 18 December 2020.[21]
On 16 May 2021, Carnival president Christine Duffy announced at Miss Universe 2020 that Miss Dominican Republic 2020 Kimberly Jiménez would christen the ship upon her debut.[22] The following day, Carnival announced Mardi Gras would begin operating under the Bahamian flag after it was previously registered to Panama.[23] Jiménez officially christened the vessel on 23 October 2021 at Port Canaveral.[24]
Port Canaveral
In order to accommodate Mardi Gras as her new homeport, Port Canaveral developed and constructed Terminal 3, a new two-story, 188,000-square-foot cruise terminal that cost US$163 million to build, becoming the largest project in the port's history.[4] Work began with the approval of the contract to demolish the existing Terminal 3 on 28 March 2018 and demolition began on 27 April 2018.[25] The first steel arrived at the site in late-November 2018.[26] Official construction began in January 2019 and had been expected to be completed by April 2020.[26] On 9 June 2020, the facility received its certificate of occupancy and was subsequently completed.[27][28]
