Abstract: The market demand for liquefied natural gas（LNG）carriers continuous to be booming with the rapid growth of the global LNG trading and the high concern of the shipping industry on the carbon reduction technology. This paper introduces the development of the LNG ship types, liquid cargo containment system, liquid cargo handling system, propulsion system, energy-saving and emission-reduction technology, intelligence technology application and independent localization of the supporting technologies. Several important development directions and trends of the key technologies of the LNG carrier are pointed out to provide clear guidance for independent and controllable key technologies of China's LNG carrier.

Key words: LNG carrier, ship intelligence, energy saving device, carbon reduction, fuel cell, LNG cargo containment system
