Abstract
In this paper, calculation methods of resistance of the ship to be towed and towline tension are discussed. When the vessel is fallen into dead ship condition then appropriate towing force have to be estimated to move the vessel from accident place to safe area. In this research, resistance of the ship to be towed and the tow hawser were considered to estimate total towline tension. Polynomial interpolation method is also applied to estimate additional hydrodynamic resistance of towline. Finally, UI program to calculate the resistance and total towline tension is developed. The developed program based on the research results is effective and convenient to use.
