A STUDY OF THE DYNAMIC STABILITY OF A RO/RO SHIP IN WAVES

A study is carried out into the dynamic stability problems of a ro/ro ship in regular and irregular waves by means of time-domain simulation. The result presented in this paper has shown that the ship can be subjected to the perimetrically excited roll motion not only in regular but also irregular waves. It is concluded from the calculation of the simultaneous effect of vertical, horizontal acceleration and roll motion on the load shifting onboard that special attention should be paid to the danger of the simultaneous effect in the design of the cargo lashing system onboard and by the onboard crew. The importance of the interaction between the roll, heave and pitch motion in the dynamic stability problem is emphasised and further research effort should be made to identify the parameters describing the interaction. Finally, the survivability of a ro/ro ship following severe cargo shifting is discussed, and consideration is given to the capsizing scenario of ro/ro ship accidents due to severe weather and sea conditions.
