1977年1月，一艘集装箱船在北太平洋波涛汹涌的海面上撞击，造成前体严重结构损伤。这艘船正处于满载状态，从美国加利福尼亚州奥克兰启航前往神户。在星际一侧火炬部分的壳板上，一条长长的脆性裂纹在纵向扩展。同侧侧壳的纵梁、腹板、纵梁等内部结构倒塌，左岸甲板和壳板发生屈曲。此外，2号舱口在平行六面体中发生了变形。本文从船体水弹性的角度，借助于断裂力学对损伤进行了研究。结果表明，船舶操纵和结构设计对于防止大型集装箱船的严重损坏具有重要意义。
A container ship suffered serious structural damage in her fore body due to slamming in heavy seas in the North Pacific Ocean in January, 1977. She was in the fully laden condition and voyaged to Kobe from Oakland, California, U. S. A. A long brittle crack propagated in the fore and aft direction in shell plating of the flare part on the starbord side. The inner structures, such as longitudinals, web frames and side stringers, on the side shell of the same side were collapsed, and deck and shell plating on the port side was buckled. Furthermore, No. 2 Hatch was distorted in a parallelepiped. In the present paper, the damages are investigated from the view point of ship hydroelasticity with the aid of fracture mechanics. The results obtained suggest the importance of ship handling as well as structural design for preventing serious damages in large container ships.
