In this paper, the authors describe the experimental results upon the hydrodynamic effects on the course keeping of ship passing near by the bridge post crossing over the channel. Model experiments have been carried out on 1/100 and 1/200th scale models of square section bridge post and full type of large tanker in circulating water tank, and the hydrodynamic moment and forces acting on the ship due to the stream around the post were measured. From the experimental results, the authors recommend as follows ; To keep the ship's course by steering with less than 15 degrees of rudder angle against the hydrodynamic interaction between ship and bridge post, ship must take her course of perpendicular to the bridge line with a ship's length of transeverse clearance.
