Abstract

The function and role of the Strategic Sealift Vessel (SSV) ship type is very important. Modifications and changes to improve the value of efficiency will be very necessary. This efficiency value is closely related to the value of Ship Resistance , where if the Resistance value goes down, the value of the ship's efficiency will rise. The increase in efficiency is then expected to reduce fuel consumption and increase speed. In several studies, ways have been improved to improve the condition, one of them is by adding a Dimple to the Surface Area of the ship, this modification will reduce the friction Resistance that the ship will receive by reducing the Wetted Surface Area that the fluid will pass at certain speeds and conditions. . This modification will be applied to the ship's Bulbous Bow section. In this way it is expected to improve the value of the Resistance produced by the Bulbous Bow installed in the ship, without having to carry out significant changes or modifications and change the shipbuilding of the existing Linesplane. Furthermore, the analysis is carried out by modeling using 2D and 3D CAD Software and Model Experiments using CFD Applications. After carrying out the entire process of Running with the CFD Software to determine the value of the Ship Resistance . The final conclusion is in the form a reduction the value of vessel Total Resistance the Running Bow section of 31.53% in the 4th variations and Fn used is 0,341. Keywords: Boulbous Bow, CFD, Dimple, Reduction, Resistance
