Kuwait Petroleum’s unit KIPIC said two sub-contractors died in an accident on Saturday at its LNG plant under construction in Al-Zour.
KIPIC said in a statement it would undertake all the necessary measures to investigate the incident.
The company did not provide any additional information.
State-owned giant Kuwait Petroleum formed KIPIC in 2016 to manage refinery, petrochemicals and LNG import operations at the massive Al-Zour complex.
The refinery and the LNG import terminal are located some 90 kilometers south of the capital Kuwait City.
A South Korean consortium consisting of Hyundai E&C, Hyundai Engineering and Kogas is in charge of building the LNG terminal.
It includes the construction of a regasification facility and eight 225,000-cbm LNG storage tanks.
KIPIC previously said it expected to launch the import facility with a price tag of about $3 billion in 2020.
