In the previous paper, we carried out model tests under wave action in order to investigate motions of a ship moored by the prevention system of ship separation from quay wall. In this paper, we introduce an approximate calculation method of ship motions under system. The obtained results are summarized as follows : (1) Excluding the wave force and moment over a range of the prevention system, we can calculate the moored ship motions under the system. (2) The ratio of dynamic wave force to static force of the system can be calculated, and our experiments are performed under the condition of same order of both forces. (3) Even if horizontal wave moment is larger than the static moment of the system, roll motions become small by an increased damping force due to the ship side wall contact with fender.
