Study Tahanan Kapal Ferry Ro-Ro Twin Skeg

Abstract

Ferry Ro-Ro, which can carry passengers, vehicles and cargo, require good hull planning to reduce resistance. This research discusses using twin skegs, a component at the stern of a ship that is modified to increase fluid flow. Although generally applied to large vessels such as LNG and tankers, this research explores the possibility of using twin skeg modifications on a small Ferry Ro-Ro. This research aims to determine the value of ship resistance, the difference in engine power from CFD numerical analysis with LHI data and fluid flow characteristics on the Ferry Ro-Ro twin skeg. The result shows that the value of ship resistance at a speed of 15 knots was 203 KN; compared to LHI data, it was 12.32% greater. However, at a speed of 17 knots, the difference is around 5.92%. The flow pattern in the hull changes shape in proportion to the ship's shape and the ship's speed.
