| Research Abstract |
In this study, we developed the numerical method to estimate the repetitive ice load in ship maneuvering in level ice for fatigue assessment of icebreakers and ice merchant ships. 1) Database of the ice breaking force was constructed by the Finite Element numerical simulation. 2) The numerical simulation code was developed to calculate the repetitive ship-hull contact and the ice load in level ice. 3) The ice load and ice breaking channels in various ship and ice conditions were calculated by our developed program.
