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

摘要

A method and apparatus for cooling and liquefying a hydrocarbon stream using a liquefaction process wherein a hydrocarbon stream is cooled and at least partially liquefied to obtain a liquefied hydrocarbon stream. In the method, one or more compressors are driven with one or more electric drivers, that are powered with one or more dual-fuel diesel-electric generators. These dual-fuel diesel-electric generations are operated by passing one or more hydrocarbon fuel streams 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 that is generated in the liquefaction process. The apparatus may be provided on a floating structure, a caisson, or off-shore platform.
