Hyundai Heavy Industries said that it has jointly developed a gas turbine-powered 174,000 m3 LNG carrier with GE Aviation and Marine, and has secured Approval in Principle on the vessel from the UK-based Lloyd’s Register.
The IMO Tier III-compliant 174,000 m3 LNG carrier is equipped with GE’s gas turbine-based Combined Gas turbine Electric and Steam system (COGES 2.0). The vessel is expected to save shipowners or operators an estimated 20 billion Korean won ($17.83 million) on the assumption that the LNG carrier operates for 20 years with an annual operating cost of $720,000, since it does not need additional equipment to handle exhaust emissions, HHI’s statement reveals.
The gas turbine-powered engine is 60 percent lighter than conventional engines and will lower operating and maintenance costs accordingly, the statement said.
Durability and low vibration/noise of the engine are also test-proven over 70 million hours of application on offshore platforms, onshore power plants, and high-speed ferry boats, it added.
