According to the structure character of WZ10-3 single point mooring, the method of lifting removal as a whole is raised. Considering the requirement of lifting removal as a whole for this single point mooring, lifting pile tool method is designed creatively inspired by pile lifting method, sleeve boring method is designed creatively inspired by conductor lifting method, and 3 other kinds of lifting methods, such as balancing padeye lifting method, blind plate lifting method and padeye lifting method, are also designed. By analyzing the technical feasibility of these 5 kinds of lifting methods and by overall considering various factors of the project, the padeye lifting method is chosen at last. In the padeye lifting design, the reason for padeye welded on the outside of the sleeve is analyzed, the advantages of padeye lifting method and ring stiffeners are also described, and finite element analysis is taken out for the structure strength check of the single point mooring lifting as a whole. It is concluded that the design of the padeye lifting method is feasible.
