Abstract

Ships must have good performance and economic value. To achieve it, optimum speed is needed with minimal engine power usage so it can increase the efficiency of fuel use. The use of engine power is closely related to the total resistance on a ship. One alternative way to reduce ship resistance is to install bulbous bow. This research aims to obtain the resistance of ships with variations in the type of bow shape of the ship. The analysis on this research uses numerical method using CFD. Variations in the modelling of bow design are; X-Bow, spherical and tapering bulbous bow. Based on the results of CFD calculations, each model is obtained, namely; the lowest value of the total resistances coefficient and total resistances model X-Bow 0,006565 and 242,76 KN, while for the spherical bulbous bow model is 0,007211 and 267,22 KN and for the lowest form of tapering bulbous bow the total drag coefficient and total resistance is 0,007368 and 273,40 KN. Referring to the results of the analysis, resistances of the ship model using the X-Bow design is the best model that can be used as an alternative if compared to spherical and tapering bulbous bow.
