Based on domestic and foreign research data,this paper summarizes and organizes the overview,structural design methods,and difficult solutions of gravity based structure (GBS) for offshore LNG (liquefied natural gas) receiving station.It also proposes the application prospects and unresolved problems of offshore GBS LNG receiving station in China.The structural design of the Adriatic Sea LNG receiving station is a typical structure of GBS,based on the semi-probabilistic limit state design approach.The finite element method is used to analyze and obtain the stress state of the structure at each stage from construction to application.The main difficulties in structural design include the temperature gradient control of concrete required for LNG tanks,the humidity gradient control of insulation materials,and the overall seismic reliability of the structure.The temperature and gradient changes are solved by embedding heating cables and installing flexible steel pads to isolate water moisture.The seismic resistance test of the structure is demonstrated through finite element analysis of the foundation structure interaction under seismic action.Due to limited information,further research is needed on the detailed design and construction of GBS,which has potential applications in future energy imports,and offshore natural gas extraction in China.
