Recently very large floating structures used as international floating airports have been studied in Japan. Many structural types for the very large structures may be feasible for real floating structures. But optimal design is not achieved yet because we do not have enough information due to lack of experience and information coming from real structures. Recent research has given us useful information of characteristic structural behavior of this 'mega-float' structure especially in waves. It is important for designers to perform optimal designs for feasible structural types and to collect a lot of information from the data. The present paper deals with some optimal design of 'mega-float' structures needed at the initial structural design. The method of structural optimization using wave-induced bending moment considering fluid-structure interaction simply is proposed. The effects of the structural types, number of stiffeners, and welding cost on the optimized design parameters obtained by optimization has been investigated and discussed.
