The cargo vessel Diezeborg was brought under control and secured after an engine-room fire on 14 February in the Baltic Sea, north-west of Gotska Sandön, Sweden. A response was initiated the same day as the ship drifted, with measures taken to prevent a potential grounding.

On 15 February, the Swedish Coast Guard vessel KBV 002 Triton connected a towline and moved Diezeborg to reduce the risk of the ship running aground at Kopparstenarna. The crew remained on board and the situation was reported as stable.

At the time of the incident, Diezeborg was sailing from Setúbal, Portugal, to Kokkola, Finland, carrying zinc concentrate. The fire was reported in the engine room and the vessel’s fixed automatic fire-extinguishing arrangement deployed. The nine people on board contained the incident, and no injuries were reported.

Coast Guard ships and helicopters arrived on scene shortly after the alert.

Built in 2000 and flying the Netherlands flag, Diezeborg is 133.41 m long and 15.85 m wide.
