Prediction of propulsive power for ships with honogeneous hull and high speed

This paper has provided the prediction of propulsive power for ships with honogeneous hull and high speed from the displacement, principal dimensions and hull form coefficients, and hull lines at the stage of preliminary, alternate and technical design respectively in which all of mathematical formulae can be employed in ship design and optimization of hull lines. A validated computation from comparison of estamation with measurement in propulsive power for a series of ship models shows that the prediction of propulsive power provided by the present method is satisfactory with engineering accuracy and can be applied to optimization for ship hull lines.
