Abstract

Indonesia experienced the development of the number of ship fleets until August 2022 there were 4,906 passenger ships, 50,419 fishing boats and 44,645 freighters compared to 2017 the number of fleets was only 27,567 ships, in 2018 the number of fleets was 29,928 and increased to 32,587. With this, naval engineers made innovations, one of which was multi-hulls such as SWATH and Trimaran. This research aims one of the innovations to determine the comparison of conventional trimaran resistance with SWATH trimaran ships. The ship model is a ship from research from a validation journal which will later be varied into SWATH. Analysis of resistance and calculation of this model using the Computational Fluid Dynamic (CFD) method with the help of ANSYS software. This resistance comparison analysis is carried out on total resistance, friction resistance, viscosity resistance, wave resistance and residual resistance with speeds at fr 0.1, 0.3, 0.5, 0.7 and 0.9. From the results obtained in CFD, that the total drag coefficient (CT) with an average difference between trimaran conventional side hull and SWATH side hull is 11%, CF gets a difference in value with an average of 8.4%, CW gets a difference in value with an average of 2.3%, CV gets a difference in value with an average of 1.3%. The results of the wave contour obtained from CFD show that the SWATH trimaran has a more regular wave contour shape than the conventional side hull trimaran, this is due to the smaller WSA (Wetted Surface Area). The resulting interference shows a ratio of 0.07%, where the lowest value is -0.0088. Keyword: Multihull, resistance, and CFD.
