HHI-GE COGES LNG Carrier Gets LR Nod

Ship Would Mark Just Second Use of a Gas-Fueled Maritime Turbine

Korea’s Hyundai Heavy Industries reports development with GE Aviation and Marine of the world’s first gas turbine-powered liquefied natural gas carrier, and said the partners have secured AIP/Approval in Principle for a 174,000-cubic-meter vessel from UK-based Lloyd’s Register.

The design features GE’s COGES 2.0 gas turbine-based combined gas turbine electric and steam system, HHI says. It has the potential to save shipowners or operators an estimated $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 turbine saves weight and space on a cargo or cruise ship, significantly enhancing revenue potential, says GE Marine.

Francisco Is the Exception

The gas turbine-powered engine is 60% lighter than conventional engines and will lower operating and maintenance costs accordingly, HHI says. The shipbuilder notes that durability and low vibration and noise have been demonstrated by more than 70 million hours of application on offshore platforms, onshore power plants, and high-speed ferries.

The GE turbine-powered vessels in operation today are military vessels or cruise ships running on conventional fuels (HHP Insight, April 23, 2014).

The exception is the Tasmanian-built Francisco, a high-speed twin-turbine ferry operating on LNG between Buenos Aires and Montevideo (HHPi, October 3, 2013).

‘Enormous Efforts’

“We have put enormous efforts into developing the world’s first turbine-powered LNG carrier in close cooperation with HHI,” GE Aviation and Marine VP Brien Bolsinger says in the HHI announcement. “With the AIP, we are proud to introduce the eco-friendly and fuel-efficient gas turbine-powered LNG carriers to the market.”

“The LNG carrier we introduce today is a culmination of the seamless teamwork of GE and HHI,” said HHI CTO Shin Hyun-soo. “We will continue to enhance our competitiveness through ongoing technological cooperation including the application of the gas turbine engine to large containerships,” he said.

Built by Incat, the world’s first high speed ferry to operate with LNG as its main fuel – now known as the Francisco – has been deemed the world’s fastest ship, having achieved 58.1 knots in sea trials off Hobart, Tasmania.

The Incat Tasmania-built, LNG-fueled, GE LM2500 turbine-powered Francisco operated by Buquebus in South America is billed as the world’s fastest ship.
