One crew member went missing during an underwater operation to remove the obstruction. After conducting a 72-hour search in the area where the incident occurred without success, the search operation was terminated.

The Taiwan Transportation Safety Board (TTSB) classified the event as a major marine occurrence per the Transportation Occurrence Investigation Act and referenced the Casualty Investigation Code of the International Maritime Organization (IMO). The Investigator-In-Charge was assigned, and an investigation team was launched to conduct the investigation.
