According to the statistics, most labor accidents happen in the mining, forestry, and ship cargo handling in this order in Japan. The danger of cargo works is mainly caused by the unstable foothold due to roll motions of a ship. It is well known that the roll motion is induced by the free oscillations accompanying with cargo handling as well as by the waves. From the field observation, it is found that the large inclination of the ship and free oscillations are followed by heavy cargo handling on a small ship, and they always make the cargo works dangerous even in a harbor. We have already investigated the damping of ship motions by using a dash-pots mooring system in waves. In this paper, how this mooring system is also effective on cargo handling is studied, and fundamental factors to design an appropriate dash-pot are shown.
