Abstarct: In the field of tourism and trade in the Persian Gulf, one of the issues is creating a suitable communication route between Qeshm Island and the southern coast of Iran in the form of a national plan considering all aspects such as economy, safety, environment, etc. Costly and risky operations are needed for underwater construction and pile driving in terms of the environment and the risk of coral destruction in this area. Thus, one of the solutions is to use a floating bridge. This study investigates this solution. The research proposal is to use a bridge with suspended spans. The piers of the bridge are pontoons that float in the sea. The hydrodynamic response of floating pontoons has been examined in this research by modeling floating pontoons in the National Marine Laboratory of the Persian Gulf Martyrs and comparing it with the numerical model of Ansys Aqwa. The result of numerical modeling indicates that the increase in the number of pontoons from one to three reduces the maximum vertical movement of the pontoons. On the other hand, the smaller the angle of the longitudinal axis of the pontoons relative to the wave direction, the lower the maximum vertical movement of the pontoons. It also shows that the increase in the draught rate of the pontoons reduces the effect of the number of pontoons on the maximum vertical movement. The research generally concludes that an economical and safe plan can be achieved in order to design floating bridges by optimizing the number of pontoons, the draught rate of the pontoons, and their angle to the possible waves of the area.
