The authors have studied on estimation of ship motions underway in heavy seas. Operators pay attention to avoid the cargo damage in this situation. It is necessary to know the relation between ship motions and cargo damage in this study. However, there is very little database related on cargo damage. In this study, the difficulty of cargo management is verified by interviews, wave and AIS database. Field observation is implemented on ship motions, accelerations on deck, and lashing wire tensions. Vertical accelerations of 1.5G occur on fore and aft deck, when pitch motion is around 2 degrees with the same peak frequencies. On the other hand, the peak frequency of lashing wire tensions is lower than that. These points have to be cleared in future studies.
