GE Marine and Lloyd’s Register (LR) have signed a Memorandum of Understanding (MoU) to identify potential gas turbine-powered commercial ship projects.
GE gas turbine systems offer power density (that is, high power in a light weight, small footprint), fuel flexibility, and an optional Dry Low NOx emissions (DLE) combustion system technology. GE’s DLE combustion system can meet Tier III IMO/Tier IV United States Environmental Protection Agency requirements now with no exhaust treatment when operating on natural gas or on liquid fuels in combined cycle.
Through the MoU LR will work with some of the leading shipyards to approve in principle GE gas turbine-powered commercial vessels.
Gas Turbine-Powered LNG Carrier
This MoU is separate of an announcement made in December 2013, whereby GE Marine, Dalian Shipbuilding Industry Company (DSIC) and LR have jointly developed a design for a gas turbine-powered LNG carrier. This carrier will provide low life cycle cost, high environmental performance and flexible design.
The initial LNG carrier design will be built around a GE gas turbine-based Combined Gas turbine Electric and Steam system (COGES) that will feature one 30 MW gas turbine, one steam turbine generator-set and two dual-fuel diesel generator-sets for low power operation and backup. However, the carrier will allow for flexible configuration of prime movers, offering total installed power of more than 50 MW, if required. Approval in Principle for the COGES arrangement is expected shortly.
