抄録

Japanese National Railways has developed a new type berth fender for railway ferry berth, The fender is mainly composed of a box shaped steel slab whose front surface is smooth, and several water pressure shock absorbers which are made of rubber bags and attached to the back surface of the slab. The shock absorbing and damping properties of the absorber were proved excellent by half scale model tests. The results of the tests were compared with the results of approximate calculation.<BR>A trially constructed fender of this type (size=8m × 4m) was fitted on a railway ferry berth in Uno port. Full size shock tests were carried out on this fender, and the results indicated the allowable berth touching speed might be doubled.
