Summary:The importance of transportation has been recognized when a city function is destroyed by natural disasters, such as the Great East Japan Earthquake or Kumamoto Earthquakes, etc. Sea transportation accounts for more than 95 percents of logistic cargos. It is also required to operate ships more efficiently and environment-friendly. This might relates to the fact that few weather database there than in the subtropical zone or the Northern Hemisphere. This study shows three measured results of rough sea navigations of 28,000DWT class bulk carrier in the Southern Hemisphere. Waves and winds are numerically computed by different models, and the computed results are validated with measured data. Moreover, the validation on ship motions is carried out using response functions. The possibility of wave estimation in the Southern Hemisphere is shown from measured and simulated results.
