This research aims to investigate the flow analysis of LNG ship due to the different shapes of the ship front. Velocity and pressure distribution of fluid at the front portion of ship are numerically calculated for the optimum ship design of front with three different ship speeds for two different front shapes of ship. These numerical calculations are only applied for the immersed part of ship at the ocean. In addition, the coefficient of pressure drag and total drag are numerically obtained. Ultimately, the energy-efficient shape of LNG ship are determined through two different body shapes with three different ship speeds.
