Nuevo avance en la propulsión de los metaneros

HHI and GE receive AIP for new gas turbine-powered LNG carrier

Hyundai Heavy Industries (HHI) has received approval in principle (AIP) for its new LNG carrier from UK-based classification society Lloyd's Register.

Jointly developed by GE Aviation and Marine (GE), the new vessel is claimed to be the world's first gas turbine-powered LNG carrier with a capcity of 174,000m³.

HHI CTO Shin Hyun-soo said: "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."

Capable of meeting IMO Tier III regulations, the new vessel will be equipped with GE's gas turbine-based combined gas turbine electric and steam system (COGES 2.0).

According to HHI, as the carrier does not require additional equipment to handle exhaust emissions, it is expected to save up to $17.83m on the assumption that it operates for 20 years with an annual operating cost of $720,000.

In addition, the vessel's gas turbine-powered engine will be 60% lighter than a conventional engine. It also offers lower operating and maintenance costs, as well as better durability and low vibration / noise.

GE Aviation and Marine vice-president Brien Bolsinger said: "We have put enormous efforts into developing the world's first turbine-powered LNG carrier in close cooperation with HHI."

In June, HHI received an approval in principle (AIP) certificate from classification society DNV GL for its SkyBench concept for mega-box ships.

The SkyBench concept has been designed to increase the cargo capacity of large container vessels by constructing the bridge and upper three decks as a separate sliding block, mounted on rails, with the option to move it over the length of two 40ft container bays.
