ABSTRACT
The crashworthiness of the striking vessel and the struck vessel should be evaluated when ship collision occurs because it can cause severe consequences. In this study, a simplified method based on analytical approach is suggested for small scale ship collision event and compare it with the solution obtained from the finite element method. The shape of the striking vessel and struck vessel are selected as a bow (bulbous bow and stem) and a double hulled structure, respectively. From the finite element results, it is confirmed that the stem case is more vulnerable than the bulbous bow case, because its sharp shape can cause the local failure of struck vessel much earlier. The way to consider the geometry effect of striking vessel called contact based method is introduced in this paper. It is verified that the finite element results and the simplified method results are found to have an appropriate correlation.
