There is a fearful possibility that damaged or capsized ships cause the secondary disaster such as giving the damage to port facilities, discharging oil spill and drifting to the coast, while the safe navigation of other ships is prevented. It is necessary to tow the disabled ships to rather calm harbor immediately in order to avoid the disasters in advance. It is also necessary to predict the towline tension and whirling motion for the towing of such abnormal hull shape. The characteristics of viscous drag working on such a hull shape have to be made clear to investigate them. This paper aims at the development of the tool giving the feed back of the result from the research of general characteristics of viscous drag concerning the shape of the damaged ships in marine accidents to predict the immediate operation at site. The database of the drag force concerning the shape of various cross sections has been prepared in this technique. The rough estimate of viscous drag can be made using the available data of damaged or capsized ships. The applicability of developed estimation method has been verified by the model experiment.
