HHI Develops Korea’s First Dual-Fuel Propulsion System for LNG Carriers

Hyundai Heavy Industries Co., Ltd. (HHI) has developed the first Korean Dual-Fuel Diesel-Electric (DFDE) propulsion system for LNG carriers.

The DFDE propulsion system uses either oil or gas, depending on the situation. It uses an electric motor like large cruise ships and submarines, not a steam turbine, which is the traditional propulsion system for LNG carriers. The DFDE propulsion system improves fuel efficiency, reacts quickly, and provides a smooth voyage.
