Norwegian Star underwent an extensive dry dock refurbishment at Vigor Industrial in Portland, Oregon, as part of Norwegian Cruise Line's NEXT fleet enhancement program. The project introduced the Five o'Clock Somewhere Bar, O'Sheehan's Neighborhood Bar & Grill, and Sugarcane Mojito Bar, while updating Ginza Asian restaurant. Passenger-area improvements included renovations to the casino, photo gallery, pool deck, and galley facilities, replacement of carpeting, flooring, and windows, and installation of interactive digital signage. Technical work included Azipod propulsion upgrades, bow thruster and stabilizer maintenance, replacement of ballast and bilge piping, upgrades to lifeboat and tender release systems, and application of fuel-efficient silicone hull coating.

Norwegian Star underwent an extensive dry dock refurbishment at Victoria Shipyards following the unexpected cancellation of its charter as a floating hotel for the 2010 Vancouver Winter Olympics. The project involved major renovations across four fire zones, including the relocation of retail shops, conversion of former retail space into a lounge, and extensive reconfiguration of passenger accommodations and public areas. Work included new suites and staterooms, modifications to Spinnaker Lounge and the aft lounge, improvements to La Cucina restaurant and the art gallery, and conversion of the bell box area. ABB also participated in technical work involving the ship's Azipod propulsion systems. Originally planned for a later shipyard visit, the refurbishment was organized on exceptionally short notice. Norwegian Star moved from dry dock to the pier on February 28, departed Victoria on March 2, and resumed passenger service March 6.
