With the advantage of easy to migration

reliable of equipment and high security features

LNG-FPSO has great significance for the development of offshore gas field. The DMR liquefaction process has high efficiency and large capacity

which has obvious advantages under the conditions of stable sea and large amount of gas. The research verified the accuracy of the double mixed refrigerant flow

using the floating DMR experimental device which belongs to CNOOC Gas Electric R & D Center. The article analyzed the sensitivity of the NG's temperature

flow rate

and compressor frequency

and gave an assessment to the maritime adaptation. The experiment showed that the DMR process would be suitable in stable sea condition and mid to large-scale LNG production

and was not sensitive to the changes of gas temperature and pressure

it can effectively reduce the system energy consumption under low load by using inverter compress.
