General cargo ship ATLANTICBORG reportedly collided with dredger while leaving Kemi Port, Finland, Gulf of Bothnia, at around 1800 UTC Jul 6. The ship had to return to Kemi after collision, not clear if the main cause is sustained damages, or investigation. Dredger wasn’t identified, it might be OPTIMUS (MMSI 230063110, length 47 meters, flag Finland), judging from tracks.
