After being towed to Mobile and disembarking its passengers on February 14, the vessel was transferred to the BAE Systems shipyard on February 15 for damage assessment, mechanical and electrical repairs, and restoration of propulsion capability. On April 3, severe winds caused the ship to break free from its moorings, collide with a dredging vessel and sustain additional exterior damage, further complicating the repair project. Following restoration of sufficient propulsion and electrical systems, Carnival Triumph departed Mobile under its own power on May 8 and proceeded to Grand Bahama Shipyard in Freeport for final repairs, safety upgrades and the installation of new Fun Ship 2.0 passenger amenities.

The repairs required the cancellation of two scheduled cruises departing Miami on February 13 and February 18, while three earlier voyages were modified to accommodate the ship's reduced speed. The maintenance project focused on correcting the propulsion problem rather than introducing new passenger amenities or undertaking a major interior refurbishment. Following the repairs, Carnival Destiny returned to service on February 20 with a shortened two-night Bahamas cruise to Nassau, before resuming its regular four- and five-night Caribbean itinerary schedule on February 22.

The ship welcomed passengers in Barcelona on June 11 for its transatlantic return to New Orleans.

Carnival Valor completed a 21-day dry dock at Chantier Naval de Marseille as part of Carnival's preparations to return the vessel to service following the COVID-19 shutdown. The ship underwent scheduled technical maintenance, inspection and repair work and received Carnival's new red, white and blue hull livery, becoming the fourth ship in the fleet to receive the new design. The yard period prepared Carnival Valor for her eventual return to passenger operations from New Orleans in November 2021.

Carnival Valor completed an extensive refurbishment at Grand Bahama Shipyard that introduced a major collection of Carnival's Fun Ship 2.0 features. New venues included Guy's Burger Joint, BlueIguana Cantina, RedFrog Rum Bar, BlueIguana Tequila Bar, RedFrog Pub, Alchemy Bar, SkyBox Sports Bar and Cherry on Top. The project also upgraded the Camp Ocean children's facilities, refreshed accommodations and public spaces, and included technical work such as installation of shoreside power capability and new hull coating.

Carnival Valor completed a scheduled refurbishment at Grand Bahama Shipyard that introduced the Serenity adults-only retreat, featuring upgraded lounge furniture, shaded seating and dedicated relaxation areas.

Costa Venezia was transferred from Costa Cruises to Carnival Cruise Line in Cádiz, Spain, on March 22, 2023 and subsequently underwent an extensive conversion into Carnival Venezia. The project created Carnival's first Fun Italian Style ship, retaining the vessel's Italian-inspired design while introducing Carnival branding, dining, beverage, entertainment and guest-experience concepts. The converted ship departed Europe in May and entered Carnival passenger service with its inaugural voyage from Barcelona on May 29, 2023, ahead of its deployment from New York.

Carnival Vista completed a thirty-day refurbishment that combined scheduled shipyard work with substantial passenger-area improvements. The ship received Carnival's red, white and blue hull livery and a Heroes Tribute Bar & Lounge replacing SkyBox Sports Bar. The casino was expanded and reconfigured, with the former Club O2 location becoming a non-smoking annex. Club O2 moved into the previous arcade space, and the arcade relocated to the former Thrill Theater. Cherry on Top and Carnival Adventures were established on Deck 4, and a Dreams Studio was added on Deck 3. Retail spaces and the Lido Marketplace were refreshed, the miniature-golf layout was revised, the outdoor children's playground became Fun Yard, and the Carnival Multiplex entrance moved to Deck 7. The ship returned to Port Canaveral following the project.

Carnival Vista underwent an emergency propulsion repair at Grand Bahama Shipyard using Boskalis' semi-submersible heavy-lift vessel BOKA Vanguard as a temporary floating dry dock. In a first-of-its-kind operation for a cruise ship, Vista was loaded onto and lifted completely out of the water by BOKA Vanguard, then transported to the shipyard while remaining supported on the vessel. The project allowed technicians to repair the ship's malfunctioning Azipod propulsion system, including replacement of bearings, after conventional large dry-dock capacity at Grand Bahama Shipyard had been rendered unavailable by an earlier crane accident.

Mardi Gras completed its first scheduled dry dock at Chantier Naval de Marseille, combining routine technical maintenance with accommodation and public-area enhancements.

Accessibility work included redesigned walkways and upgraded features in public areas and guest cabins. The refurbished ship resumed passenger service from Barcelona on October 16, 2025, beginning a transatlantic voyage to Port Canaveral.
