The America Bureau of Shipping (ABS) has granted GE’s Marine Solutions and Hudong-Zhonghua Shipbuilding (Group) Co. Ltd (HZ) Approval in Principle (AIP) for a jointly developed LNG carrier design to be powered by GE’s Combined Gas Turbine Electric and Steam (COGES) system.
The COGES system will feature a GE LM2500-family gas turbine generator, a heat recovery steam generator (HRSG) and a steam turbine generator. The LM2500-family gas turbine used in the COGES system is derived from GE’s proven CF6 aircraft engines.
GE’s Brien Bolsinger, Vice President, Marine Operations, said: “We are delighted to work with Hudong-Zhonghua Shipbuilding on this 178 000 m3 LNG carrier design that will use our efficient, reliable and dual-fuel marine gas turbine […] With AIP in hand from ABS, customers can now procure this LNG carrier that is capable of meeting Tier III International Maritime Organization and Tier 4 United States Environmental Protection Agency emissions requirements today.”
HZ President, Chen Jun, said: “Thanks to the compact and lightweight attributes of GE’s COGES arrangement, customers can realise an additional 4000 m3 of LNG cargo space vs a traditional 174 000 m3 LNG carrier powered by dual fuel diesel engines […] Also, since the GE gas turbine is dual fuel capable, it can operate either on the carrier’s cargo of boil off gas or on Marine Gas Oil to provide for all power and propulsion.”
Bill Shi, ABS Vice President of Engineering, Greater China Division, added: “New technologies and innovations are essential ingredients for sustainable growth of the marine industry and protection of our natural environment […] By evaluating this new design concept jointly developed by Hudong-Zhonghua and GE and granting this milestone AIP, we have acknowledged that the eco-friendly propulsion system is in compliance in principle with the requirements of the ABS standards and international regulations. We are pleased to be an integral part of this joint development project with a great potential to reduce exhaust emissions.”
