Resistance Comparison of Flat Plate and Conventional Streamline Vessel

Abstract

There was a phenomenal vessel which has unique hull shape, the shape of the hull is flattened not conventional streamlined as normal vessel. This phenomenal design is dedicated for small vessels such as fishing vessel, patrol vessel and a prototype has been built. This design raised a question regarding the resistance compared to conventional streamline vessel. This paper compares a flat plate vessel with 282.56 ton displacement with a conventional vessel with same displacement and same speed. The resistance comparison was conducted using Computational Fluid Dynamic (CFD) on each ship with speed range 5-10 knots of operational speed. The results of the CFD shows that the resistance of flat plate ship is higher compared to conventional vessel for 5 knots speed. The resistance value for 5 knots of flat plate vessel is 11,618 kN while the conventional vessel shape is 9.23kN. While for 10 knots speed, the flat plate vessel is also higher compared to conventional vessel with 54.53 kN for flat plate and 49.96 kN for conventional vessel.
