The import of LNG plays an important role in China’s natural gas supply system. Based on the analysis of the status of berth construction，the type of LNG vessel，ship density and berth utilization in China’s coastal and sub-regional liquefied natural gas （LNG），this paper puts forward the conclusions that most LNG berth capacity in coastal areas of China has not been fully released and the utilization of LNG berths in local areas is not balanced in off-peak season due to various factors such as unbalanced consumption demand and inadequate capacity of supporting facilities. Furthermore，according to the distribution law of LNG ship structure and ship density in each region，the utilization rate of LNG berths is calculated in light and peak seasons，and the average utilization rate of berths in coastal areas and the parameters of the utilization rate of berths with the highest peak month in some areas are put forward. On this basis，combined with the characteristics of LNG berths operation and ship supervision，the problems existing in the operation of LNG berths in coastal areas are pointed out and corresponding suggestions are put forward. The research conclusions can provide reference for regional LNG port planning and design.
