Analisis Tahanan Kapal Berlambung Planning Hull Deadrise Angle 15 Derajat Pada Stepped 2U Menggunakan Metode Numerik

Abstract

One way to modify a hull is by installing a stepped hull. The modification is conducted to achieve a ship design that ensures performance. The basic principle of using a stepped hull is to reduce the wetted surface area and decrease the ship's resistance, thereby improving its performance. The method used in this research is a numerical method for analyzing the ship's resistance. Based on the resistance analysis on the 15-degree deadrise angle hull with a 2U stepped design, it is known that the total resistance of the ship tends to decrease with the addition of stepped and an increase in the speed and trim of the ship. The ship model with 3-stepped 2U has a smaller resistance value than the model with 1-stepped 2U and 2-stepped 2U. Hence, the addition of stepped to the ship model can reduce resistance
