According to an enlargement of a ship, the case in which the length of a mooring quay wall is insufficient is occurred. In such a case, it is reported that some cutting accidents of mooring lines are happened. In this paper, the experiments on the moored ship motions are carried out by varying length of quay wall. The obtained results are summarized as follows: (1) The short period ship motions don't vary much by jutting out the bow from a quay wall. (2) The moored ship motions caused by a long period wave which is induced at the starting time by the wave generator become considerably large in the case of the short quay wall. (3) The ship motions along the short quay wall can be calculated fairly well in the range of short wave periods by strip method, but not in the range of long wave periods owing to three dimensional effects.
