Abstract：A docking block design optimization method for the deepwater semi-submersible crane and pipe-laying vessel is introduced. This method includes the optimization design of docking block layout and size, the optimization design of docking block under multi-objective conditions and the robust design in the presence of uncertain quantity. By adopting the above method, the layout of the docking block can be optimized, and the materials can be saved in the condition of ensuring security and reducing deformation.
