Liquefied natural gas (LNG) plays an increasingly vital role in the global energy consumption market. LNG is transported between ports through vessels, while current studies on LNG trade patterns and their evolution at the port scale is relatively limited. In this paper, we adopt some complex network indices and methods to detailed analyze the trade patterns of the global LNG transportation network using mass vessel trajectory from 2013 to 2017. The results show that: 1) LNG transportation shows multiple transshipment characteristics; 2) LNG trade network forms a series of trading communities around hub ports. Among them, Singapore, Ras Laffan and Khawr Fakkan play extremely important roles; 3) ports within the same community are more geographically concentrated; 4) the global LNG trading network has evolved into three closely linked trading regions.
