On 12 Jan 2024, a 27-year-old subcontracted worker died after he was injured in an explosion from grinding work during rudder production. This was the first fatal accident at the shipyard since Hanwha Ocean acquired Daewoo Shipbuilding & Marine Engineering (DSME).

On 24 Jan 2024, it was reported that a second subcontracted worker, a 31-year old, was found dead after he was diving to remove foreign objects from the hull. Hanhwa Ocean commented " [t]he company immediately reported the accident to the police and the Ministry of Employment and Labor and is doing its best to identify the exact cause".

The labor ministry has begun looking into whether Hanwha Ocean violated the Serious Accidents Punishment Act (SAPA).
