Abstract
The development of technology in the ship industry is remarkable with many new innovations in the effort to improve ship performances. Ship resistance is one of the aspects that is very important to be comprehended the ship's characteristics. One of the innovations to reduce ship resistance is by adding hull vane to the ship hull. Hull vane is a fixed foil placed under the water line at the stern of the ship. This study is aimed to determine the effect of ship resistance after the addition of the hull vane and the location of the hull vane on the ship hull. This study utilizes a computer application program Computational Fluid Dynamic (CFD). The foil used is NACA 2415 type with s parameters angle of attack 5°, span foil 9.76 m, and chord hull vane length 1.15 m.. Investigations are further carried out on the variation of the vane hull at 2 different positions and implementation of single foil and double foil configurations. The results of this study indicate that the installation of a single foil hull vane on a ship can reduce vessel resistance and in contrast for the installation of double foil. In the case of single foil and its position at 50% of T = 2.9 m the resistance is found to be most optimally reduced when the vessel is operated at Froude number Fr = 0.342. The reduction in the total vessel resistance is 20.135% in comparison to the ship without a hull vane.
