GE Marine Solutions (GE) today, at the Marintec China 2017 industry trade exhibition, announced that, along with Hudong-Zhonghua Shipbuilding Company (HZ), they have received ABS Approval in Principle (AiP) for their jointly developed design of a 100 MW liquefied natural gas (LNG) power supply vessel, which features GE's COmbined Gas turbine, Electric and Steam (COGES) system.

"This AiP demonstrates the completion of the preliminary design of the 100 MW LNG power supply vessel based on our COGES system," said Brien Bolsinger, Vice President of Marine Operations at GE.

"This configuration is ideal for utilities and other applications that require power as the ship will export electricity to a land based electrical transmission system. Customers will get better environment performance, reliability inherited from GE's aviation flight engines, and a more flexible, compact arrangement."

GE Marine Solution explains that the LNG power supply vessel is equipped with three sets of COGES systems, each of which features one GE LM2500+ gas turbine generator, one heat recovery steam generator (HRSG), and one steam turbine generator.

LNGC Conversion to Gas Turbine-Based Propulsion

Separately, GE also announced that, along with Dalian Shipbuilding Industry Co. Ltd. (DSIC), it has completed a preliminary design for the conversion of a steam turbine powered LNG Carrier (LNGC) to a gas turbine-based propulsion system.

"We are delighted to work with the DSIC team to develop this new concept of a LNGC power system conversion," said Bolsinger.

"This feasibility study provides ship owners a competitive retrofit solution for 10 to 15 year-old steam-powered LNG carriers."

Last year, GE signed a multilateral memorandum of understanding (MoU) for the joint development of a liquefied petroleum gas (LPG)-fuelled ferry design - said to be the world's first COGES ship to be powered by LPG.
