Key Aspects:
- Norwegian Sun’s technical issues disrupted a second consecutive Baltic sailing after repairs in Copenhagen took longer than expected.
- Norwegian Cruise Line cancelled the ship’s Oslo call, compensated guests, and refunded shore excursions.
- The cruise line has not reported any additional mechanical issues since departing in the evening of July 4, 2026.
Norwegian Sun’s propulsion problems continued to affect its Baltic sailings after Norwegian Cruise Line cancelled the ship’s scheduled July 4, 2026, call in Oslo, Norway.
The cancellation marked the second consecutive Baltic voyage affected by the propulsion problems. The cruise line had shortened the ship’s previous sailing to bring the 78,309-gross-ton vessel to Copenhagen on June 29 for repairs.
Propulsion systems provide the power that moves and maneuvers a ship through the water. When they are not operating at full capacity, cruise ships need to reduce speed and adjust their routes.
Although significant progress on repair work was made ahead of Norwegian Sun’s subsequent July 3 scheduled departure, the cruise line needed additional time and did not set sail until 11:00 p.m. on July 4.
The extended stay forced the ship to cancel its scheduled July 4 call in Oslo but preserved the remainder of its Baltic itinerary.
In a letter to guests, Norwegian Cruise Line said its “technical teams have continued working diligently to complete the repairs needed to restore the ship’s optimal operating capabilities.”
“To accommodate the final stages of these repairs while maintaining our commitment to the safety and comfort of our guests and crew, Norwegian Sun will remain overnight in Copenhagen, Denmark, for an additional evening,” the letter stated.
The cruise line also confirmed that Oslo, the cruise’s first scheduled call, would be removed from the itinerary.
To compensate guests, Norwegian Cruise Line provided a $100 non-refundable onboard credit per stateroom, equivalent to $50 per guest for the first two guests in each cabin.
Shore excursions booked through the cruise line for Oslo were automatically cancelled, with refunds issued as onboard credit. The overnight stay also gave guests additional time in Copenhagen before the ship departed.
After departing Copenhagen, Norwegian Sun has continued the remainder of its Baltic itinerary with scheduled calls at Warnemünde (Berlin), Germany; Gdynia (Gdańsk), Poland; Klaipėda, Lithuania; Riga, Latvia; Nynäshamn (Stockholm), Sweden; Tallinn, Estonia; and Helsinki, Finland, where the voyage is set to conclude on July 12.
Norwegian Sun’s Repairs Appear Complete
Norwegian Sun’s technical problems began during a previous 9-night Baltic cruise that departed Helsinki on June 21, 2026. The propulsion issues forced the vessel to operate at reduced speed, prompting Norwegian Cruise Line to revise the itinerary multiple times as the voyage progressed.
The first change came when the ship cancelled its June 23 call at Nynäshamn, replacing the stop with a sea day. Two days later, the cruise line cancelled visits to Klaipėda and Gdynia, adding a call at Rønne, Denmark, and shortening time in remaining German ports.
Rather than waiting until the voyage ended, Norwegian Sun arrived in Copenhagen on June 29, giving technical teams additional time to diagnose and repair the propulsion system.
Since departing Copenhagen on July 4, Norwegian Cruise Line has not announced any additional itinerary changes related to mechanical issues. Several guests sailing aboard the 1,878-passenger Norwegian Sun have also shared on social media that the ship is operating normally.
