Teamwork For LNG Carrier Development
GE Marine, DSIC, Lloyd’s Register cooperate in joint design
GE Marine, Dalian Shipbuilding Industry Co. (DSIC) and Lloyd’s Register announce they have jointly developed a design for a gas turbine-powered LNG carrier. The companies said this carrier will provide low life-cycle costs, 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 (COGES) system that will feature one 25 MW gas turbine, one steam turbine gen-set and two dual-fuel diesel gen-sets for low power operation and backup.
GE said the carrier will allow for flexible configuration of prime movers, offering a total installed power of more than 50 MW, if required. The GE gas turbines can be equipped with a GE dry low emissions (DLE) or single annular combustion system – both capable of meeting Tier 3 IMO/Tier 4 U.S. Environmental Protection Agency (EPA) requirements with no exhaust treatment and no methane slip, the company said.
Lloyd’s Register said it recently spearheaded and completed a preliminary hazard identification (HAZID) study, the first in a series of studies to be performed on the COGES LNG carrier that delved into the carrier’s hazardous areas, structural integrity, safe separation, pipe routing and ventilation. Lloyd’s Register will contribute a series of risk assessment studies during the design development, leading to a safety case document that meets, or exceeds, the most onerous bidding qualification requirements for new technologies for shipping for LNG projects.
