LR issues Approval in Principle for joint GE Marine and DSIC gas turbine-powered LNG carrier design
GE Marine and Dalian Shipbuilding Industry Company (DSIC) has obtained Lloyd’s Register’s (LR) Approval in Principle (AiP) for the jointly developed gas turbine-powered LNG carrier design, the two companies announced today at the Marintec China 2015 trade show.
The LNG carrier design allows room for more cargo – some 4,000 m3 of additional space in the same size hull – along with low emissions and the flexibility to operate on LNG or liquid fuel. The LNG carrier will be built around a GE gas turbine-based COGES (COmbined Gas turbine, Electric and Steam) system that will feature one 25-megawatt gas turbine, one steam turbine generator-set and a heat recovery system including gas combustion unit.
The carrier will allow for flexible configuration of prime movers and 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 III IMO/Tier IV United States Environmental Protection Agency requirements now with no exhaust treatment and no methane slip.
LR spearheaded and completed a preliminary hazard identification (HAZID) and hazard and operability (HAZOP) study and a COGES Operation Modes evaluation.
