Abstract Based on the conceptual design of LNG offloading system for LNGFPSO (liquefied natural gas floating production storage and offloading unit), a 1∶1 model of the floating LNG offloading process from LNGFPSO to LNG carrier was established. Detailed simulations were conducted and the main parameters, in particular the influences of the flow rate and the height difference of pipeline on the pump head and BOG (boil of gas) of the LNG offloading processes were quantitatively analyzed with the Aspen plus software. The results indicate that there are the dissimilar influences of the flow rate on the pump head and BOG therefore there would be an economic flow rate for practical design. The height difference of pipeline has obvious influence on the pump head for LNGFPSO offloading.
