Partners develop LNG carrier propulsion first
Hyundai Heavy Industries (HHI) and GE Aviation and Marine have jointly developed the first LNG carrier to be powered by gas turbine, and are working towards the first application on large containerships.
The 174,000m3 vessel, equipped with GE’s combined gas turbine electric and steam system COGES 2.0, has secured approval in principle (AIP) from Lloyd’s Register. The IMO Tier III compliant gas carrier is anticipated to save or operators an estimated KRW 20 billion (US$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.
The gas turbine-powered engine is said to be 60% lighter than conventional engines, lowering operating and maintenance costs accordingly. Durability as well as low vibration and engine noise have been proven over 70 million hours of application on offshore platforms, onshore power plants, and high-speed ferryboats, the partners noted.
Brien Bolsinger, vice president of GE Aviation and Marine, said: “We have put enormous efforts into developing the world’s first turbine-powered LNG carrier in close cooperation with HHI. With the AIP, we are proud to introduce the eco-friendly and fuel-efficient gas turbine-powered LNG carriers to the market.”
Shin Hyun-soo, chief technology officer of HHI, added: “The LNG carrier we introduce today is a culmination of the seamless teamwork of GE and HHI. We will continue to enhance our competitiveness through ongoing technological cooperation including the application of the gas turbine engine to large containerships.”
