Denmark has detained the containership Nora after authorities questioned the validity of its flag registration and certification documents. The Danish Maritime Authority confirmed that the vessel will remain under detention until a flag state proves it is properly registered and fully certified.
According to Danish broadcaster TV 2, the ship had been flying the Comoros flag. However, when Danish authorities contacted Comoros, they were informed that the vessel was “not correctly registered.” During further questioning, the ship reportedly raised an Iranian flag, prompting officials to issue a detention order.
The Danish Maritime Authority said in a statement that the vessel “has been detained until a flag state proves to the Danish Maritime Authority that the ship is registered and fully certified.”
Reuters reported that the ship, now named Nora, shares the same IMO number as the containership Cerus, which was sanctioned by the United States in July 2025.
When the United States imposed sanctions, the vessel was identified as Cerus and was reportedly registered in St. Kitts and Nevis. In October 2025, the ship changed its name to Nora and claimed registration in Aruba, later shifting to Comoros two months afterward.
Сontainership is listed with ownership in Dubai. Bureau Veritas withdrew the vessel’s class certification in August 2025 for “non-compliance with conditions of class/recommendations.” Equasis lists its last known inspection as taking place in 2022.
Denmark’s TV 2 reported that the vessel went dark while in St. Petersburg, Russia, in mid-January before sailing west into the Baltic Sea and reaching Skagen on January 22. The following day, it anchored less than 20 miles east of Aalbaek, Denmark, where it has remained for 28 days. Danish media reported that a Danish patrol ship and a Danish Armed Forces sea drone were observed near the vessel.
According to Danish reports, the vessel has passed through Danish waters at least 10 times over the past year during frequent voyages to St. Petersburg, reportedly ceasing to transmit position data as it approached Russia.
In a separate account, Danish authorities stated that the inspection had been completed and no major safety issues were found.
