Abstract

It is necessary to study on the safety of "the refugee of harbour" from the viewpoint of port planning, too. Recently, breakage casualties of stranded ships become very serious in the port operation and the coastal environment. However, these problems have not been discussed among the coastal engineering and shipbuilding, neither. In this study, we summarize the importance of this point by showing the statistic of casualties. Then, the strength of ship hulls is caluclated with strip method and the basic dynamics of material, when ships are designed to navigate in the ocean. Since the calculated results cannot explain the breakage casualties, the possibility of the enlarged stress due to the crack is also considered as a simple example. The results can explain that the breakage of stranded ships may be caused by the enlarged stress due to cracks on the ship hull. Therefore, the safety of coastal areas outside harbour should be considered totally with anchored ship motions and fracture mechanics of ships in detail in the future.
