On May 24, a serious fire broke out aboard a cargo vessel berthed at the Grevenhofkai terminal in the Kuhwerder port area of Hamburg, Germany. The incident left seven crew members and one firefighter injured.

According to the German fire department, the first emergency calls were received in the afternoon, reporting thick smoke billowing from the stern of the roughly 90-metre-long vessel Jolyn. The fire originated in a storage area on board. Crew members attempted to extinguish the blaze themselves but were unable to bring it under control. After three hours of intense firefighting, the fire was ultimately extinguished. The fire department subsequently inspected the affected area and monitored the temperature of relevant sections. After confirming there was no risk of re-ignition, the scene was handed over to the police for further investigation.

A total of eight people sustained serious injuries in the incident. One person received medical treatment at the scene, while the other seven—including one firefighter and six crew members—were transported to hospital.

Access to the vessel is currently restricted, and anyone entering the ship is required to wear respiratory protective equipment. The Hamburg port authorities have issued a detention order against the Jolyn, prohibiting its departure. Police plan to send fire investigators on board on the 26th to further determine the cause of the fire. As of now, the specific cause of the fire remains unclear.

The Jolyn is a small general cargo vessel with a deadweight tonnage of approximately 3,600 tonnes, operated by Royal Wagenborg. Built in 2007 and registered in the Netherlands, the vessel had arrived in Hamburg earlier that day from the port of Hull in the United Kingdom.
