LNG Cargo Compressor: Working Principle & Fix | SEAMEN

LNG Cargo Compressor: Working Principle & Fix | SEAMEN

Gas Carriers, Insights
Working Principles of the Cryogenic LNG Cargo Compressor Boil-off gas management aboard modern liquefied natural gas carriers relies on the continuous, precision operation of the shipboard LNG cargo compressor. Unlike LPG reciprocating machinery, LNG compressors handle cryogenic methane vapor (CH4) at temperatures down to -140°C and colder. Designed as high-speed centrifugal or multi-stage radial units driven by electric motors or steam turbines, these machines rotate at speeds between 12,000 and 15,000 RPM. They are engineered to compress large volumetric flows of cryogenic gas without mechanical seizing, seal degradation, or thermodynamic surging. Onboard an LNG tanker, compressor installations are segregated into two distinct operational duties under the IGC Code: Low-Duty (LD) compres...
