Analysis of the internal-design factor to the patrol boat: A study of hull resistance using Savitsky and Holtrop approaches

Abstract

The issue with sea transportation is the high operational costs due to fuel consumption. Ship resistance generated by the shape of the ship hull is one factor that affects efficiency. Internal factors that affect the hull’s resistance include the frontal area, appendage area, and appendage factor. In previous studies, research has been conducted on the effect of adding appendages to the hull and hull design variations on resistance. However, research on the influence of internal factors, e.g., rudder surface area and frontal area of the bow on hull resistance of monohull-type ships still need to be done. In this study, the effect of the type of internal factor is to be by considering the calculation of the hull resistance using the Savitsky method and Holtrop formula. Several hull designs with variations on adding the applied appendages are proposed to be the subjects of this study. The effect of the internal factors on the hull performance, i.e., resistance, is quantified to conclude the parameter which provides the highest effect.
