According to the structure character of WZ10-3 single point mooring,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, and sleeve boring method is designed creatively inspired by conductor lifting method, and 3 other kinds of lifting methods, such as balancing lifting padeye method, blind plate method and padeye method, have also been designed. By analyzing the technical feasibility of these 5 kinds of lifting method, and by overall considering various factors of the project, padeye method was chosen at last. In the padeye lifting design, the reason for padeye welded on the outside of the sleeve is analyzed, and the advantages of padeye lifting method and ring stiffeners are also described, and FEA has been taken out for the structure strength check of the single point mooring lifting as a whole, and the conclusion is that the design of the padeye lifting method is feasible.
