METHOD OF COOLING AND LIQUEFYING A HYDROCARBON STREAM, AN APPARATUS THEREFOR, AND A FLOATING STRUCTURE, CAISSON OR OFF-SHORE PLATFORM COMPRISING SUCH AN APPARATUS

A method and apparatus for cooling and liquefying a hydrocarbon stream (10, 20) using a liquefaction process wherein a hydrocarbon stream is cooled and at least partially liquefied to obtain a liquefied hydrocarbon stream (20, 50, 70). In the method, one or more compressors (32, 34, 36) are driven w...

Beschreibung
Zusammenfassung:	A method and apparatus for cooling and liquefying a hydrocarbon stream (10, 20) using a liquefaction process wherein a hydrocarbon stream is cooled and at least partially liquefied to obtain a liquefied hydrocarbon stream (20, 50, 70). In the method, one or more compressors (32, 34, 36) are driven with one or more electric drivers (Dl, D2, D3), that are powered with one or more dual-fuel diesel-electric generators (300). These dual-fuel diesel-electric generations (300) are operated by passing one or more hydrocarbon fuel streams (96) to the one or more dual-fuel diesel-electric generators, wherein at least one of the one or more hydrocarbon fuel streams comprises a stream (40, 60) that is generated in the liquefaction process. The apparatus may be provided on a floating structure (52), a caisson, or off-shore platform.
