INVESTIGATION ON SOME CONVENTIONAL HULLS FORMS OF THE PREDICTIVE ACCURACY OF A PARAMETRIC SOFTWARE FOR PRELIMINARY PREDICTIONS OF RESISTANCE AND POWER

Preliminary prediction of resistance and power is a fundamental aspect the ship design process since they directly influence developments process, fuel consumption costs, environmental impact from early stage. Parametric predictions power, based mainly on statistical regression models that are also ideal for computer programming, often performed during initial stages, providing rapid optimisations minimum resistance. The paper aims to present results comparative analysis some conventional hulls predictive accuracy program developed by author parametric ships. (entitled Ship Power V 1.0) in Visual Basic 6.0 environment two well-known Holtrop Van Oortmerssen. can perform detailed coefficients, propeller thrust, hull efficiency, wake, trust fractions, with no restriction number velocities. In this study, only considered. Results computational procedures 1.0 versus experimental data, against another commercial software, three Ridgely-Nevitt trawler series KCS have shown good level reliability as other software.
