Many researches for a Semi-submersible Type Megafloat have been done on the middle-scale floating airport. However, few researches have been done from the viewpoint of the design of an elastic response. A characteristic of the elastic response must be designed under the constraints that a structural response is small enough and a safety of the structure is guaranteed. This is a subject to be investigated further. In this paper, in order to find the optimal form of a semi-submersible type megafloat, efficient optimization procedure is proposed. An objective function based on a concept of a risk is proposed in this optimization. This function unifies the structural weight and requirements of strength and functionality of the Megafloat such as a motion and an elastic response. To reduce heavy burden of calculation, a simplified analysis model with sufficient precision and short calculation time was developed and used for the optimization. The simplified analysis model was consisted of the equation of motion of a rectangular plate. Using this model, the value of the objective function was optimized and more efficient form of a semi-submersible type megafloat could be obtained.
