For the purpose of long duration of use, a new type offshore floating airport which consists of multiple removable supporting units and uniform elastic deck is proposed. This first report describes the basic concept of design and the feasibility study on stability, deflection in waves for both intact and one unit lost condition supposing repairing. The elastic responses under an impact load, considering the landing or clash of airplane on deck, are studied. Numerical simulations based on an approximate method (beam theory) are performed by assuming load as a rectangular impact plus step function and the results are compared with experiments. The deflection in waves are calculated by using mode superposition approach. Furthermore, The influences of loss of one unit on deflection and bending moment are discussed based on the experiments in regular, irregular long and short crested waves.
