The collision occurred during the night of July 11-12 in the port's navigation channel. It involved the Sea Honor, a Tuvalu-flagged cargo ship leaving the port, and the Cyprus-flagged Black Rhino, which was entering the harbor. The Black Rhino sustained damage near its bridge and was at risk of sinking. According to preliminary findings from the Port Authority of Douala, a steering failure aboard the Black Rhino may have caused the accident. Any prolonged disruption to the navigation channel could therefore affect imports, exports, and supply chains in all three countries.
