In order to optimize the multi-functional buoyancy tanks design scheme, and further explore the potential role of the semi-submersible ship, taking the maximum net buoyance originated in multi-functional buoyancy and the average annual cost in the life cycle as the objective functions, a bi-objective optimization model of multi-functional buoyancy tank was established, which integrated the technical and economic performances. The weighted ideal point method was used to transform the bi-objective optimization problem into a single-objective problem to solve the model. The material selection and the optimization design scheme of corresponding multi-functional buoyancy tanks were determined by the example calculation, and the validity of the model was verified. The sensitivity analysis was used to summarize the influence of steel price and corrosion rate on the average annual cost of multi-functional buoyancy tanks and the maximum net buoyance available, which provide a theoretical basis for the optimal design of multifunctional buoyancy tanks.
