In the design of the LNG terminal，the design of the breasting dolphin location is most important. Generally，the breasting dolphin location is designed based on the coefficient requirement in the relevant standards. But it is not suitable for all LNG vessels. Therefore，the paper researches on the compatibility of breasting dolphins to various LNG vessels. Analyzing the storage capacity，tanker type，and appearance characteristics of the LNG vessel，introducing the berthing guidelines for the LNG vessel，and expounding the arrangement of the breasting dolphin based on an overseas 10，000～220，000 m3 LNG vessels project，we conclusde that the suitable breasting dolphin location isn’t symmetrical about the working platform and the distance between the working platform and breasting dolphin at stern should be increased properly.
