Abstract: The components of the multi-point mooring system are analyzed and selected according to the characteristics of the ship type and the operation sea area, in order to meet the design requirement of refitting a LNG carrier to a FSRU and to ensure the safety of the follow-up operation of the FSRU. A time-domain coupling analysis is carried out for the refitted mooring system under the environments of wind, wave and current by using the mooring calculation software, resulting in the maximum force and maximum displacement of the mooring line and anchor under the various operation conditions. The results show that the refitted mooring line and anchor can meet the engineering requirement, and the hull can meet the strength requirement due to the better controlled hull displacement. The relevant conclusions can also provide references for the design of other similar projects.
