Narrative

TNS Catcher left Busan Port on the morning of 2 September 2026 to assist the Liberia-flagged container ship MSC Ikaria VI. At about 13:29 local time, the South Korean tug capsized in waters approximately 9 km from Oryukdo, Busan. The tug carried eight people, comprising six South Korean and two Indonesian crew members.

MSC Ikaria VI rescued one Indonesian crew member. The Busan Coast Guard recovered a South Korean crew member unconscious, but he was pronounced dead after transfer to hospital. Six crew members, reported as five South Korean and one Indonesian, remained missing on 3 September. TNS Catcher later sank, and the Coast Guard and Navy continued air, surface and underwater search operations.

Preliminary Coast Guard reporting described a three-tug manoeuvre: tugs were positioned at each side of the container ship's bow, with another at the stern. TNS Catcher was on the starboard bow and reportedly turned to starboard before rolling to port. Investigators were examining whether towline forces and the speed or timing of the turn contributed. A collision between the tug and the container ship was ruled out in the preliminary account. These are not final findings; the cause and any responsibility remain under investigation.
