Abstract

The speed-power prediction is one of the most important functions of towing-tank facilities. Generally, ITTC-1978 extrapolation method is employed for the full-scale powering prediction. During the procedure, the friction resistance line plays a major role to predict both model- and full-scale resistance. In this paper, the form factors determined by ITTC-1957 line for several kinds of vessels are compared with the values obtained using the lines proposed by Grigson(1993) and Katsui et al.(2005). Resistance and self-propulsion coefficients predicted by three different friction resistance lines are minutely analyzed. Finally, brake powers and revolutions estimated by flat plate friction resistance lines of Grigson and Katsui et al. are compared with the results obtained from ITTC-1957 line.
