Abstract
In the previous papers, we proposed the prevention system of ship separation from quay wall. In this paper, we carry out a small scale model test which is similar to an actual mooring ship in order to clear some problems for practical application under wave condition. The obtained results are summarized as follows : (1) When moored ship is supported by the system, the center of roll motion becomes the lowest point of the system. (2) As the result, the distance between ship's body and the system becomes maximum at the water surface and becomes minimum at the lowest point of the system. (3) When the system's elasticity is hard, ship's body is apt to separate from the system. (4) High wave hight and long wave period are factors for enlargement of leak water into the system.
