The Xianrendao port area is an important large-scale comprehensive port area in the Bohai-Rim region，which has the spatial pattern of being encircled by double dikes，with many large-scale berths and dense ship flow.Liquefied natural gas（LNG）terminals are of particularity and exclusiveness.To tackle the problems in the LNG terminal siting and planning in the encircling basin，taking the Xianrendao port area as an example，we integrate multiple model technologies to study navigation safety，navigation impact，land safety，berth layout，space utilization，etc.Then the scheme of site selection and the berth and water area layouts of the terminal is proposed.This research provides key technical support for the construction of an LNG terminal in the Xianrendao port area.
