Four workers were killed in an explosion on an oil tanker under construction at an STX Offshore & Shipbuilding plant in Changwon, South Gyeongsang Province, the national fire agency said Sunday.
The accident occurred at 11:37 a.m. at the plant in the city located some 450 kilometers southeast of Seoul, the agency said.
The workers in their 30s to 50s were painting inside a 12-meter-deep oil tank at the time of the accident.
The fire agency recovered the bodies of the three victims.
The oil carrier with the capacity of 74,000 tons is reportedly scheduled to be delivered to a Greek shipping company in October.
Authorities are looking into the cause of the explosion. (Yonhap)
