“…The shortcomings of the flat hull ship need to be improved by conducting research to solve the problem of the ship's resistance. The magnitude of the resistance value of a ship will affect the amount of power needed to move the ship resulting in high fuel consumption and ship operational costs [6][7][8][9]. The Marine Environment Protection Committee (MEPC) of the International Maritime Organization (IMO) issued a regulation to increase energy efficiency on ships to reduce carbon emissions [10].…”

Flat hull ship has some advantages in the manufacturing aspect which are relatively easy to fabricate and does not require high technology equipment. This ship has a weakness where the resistance of flat hull ship is bigger than the other ships among streamlined bow. A factor that influences the ship resistance is the type of bow. So, this study is needed to investigate the effects of bow design and ship resistance. This study aims to reveal the influence of various bows design on resistance and speed of flat hull ship. This study method is numerical analysis using Maxsurf software. The analysis was carried out on four types of bow direction for flat plate hull types, namely Raked Bow, Maier Form, Raked Bow II, and Plumb Bow. The result shows that the flat hull ship with the Raked Bow had the lowest resistance and power. Meanwhile, the flat hull ship with raked bow II had the highest resistance. These results can be a guide for the shipping industry on development and production, and for other researchers in developing the flat hull ship.

“…When it comes to green shipping, one of the main concerns about ship hydrodynamics is resistance reduction. As it is well known, employing excellent hull forms or optimizing hull lines with low resistance in ship design stage is an effective measure for this goal [3][4][5][6]. However, it usually requires modifications to hull lines, which may cost lots of money and time for ships in operation.…”

The paper aims at conducting trim optimization for a hull to reveal the influence of trim on wave resistance by a potential-based panel method coupled with a response surface method. First, a numerical program for solving the linear free-surface flow problem of a hull moving with a uniform speed in calm water is built by the panel method. The S60 hull model is used to validate the numerical procedure. Next, calculation for hull is performed with two different trims at a wide range of Froude number; resistance test is conducted to validate the numerical method in demonstrating the influence of trim on wave resistance. Finally, a response surface of wave resistance is constructed with respect to variations of trim and Froude number, using the database of wave resistance calculated by the surface method. In this way, a framework is developed to perform trim optimization. The optimum trim point for the present hull shows a significant improvement in both wave resistance and total resistance, compared with that of even keel and the worst trim point. The optimization framework is proved to be effective in energy saving due to resistance reduction.

“…Javanmardi et al worked the prediction of wave patterns at large distances from a moving body in a confined channel [21]. In order to minimize the total resistance of a ship, an optimization of the hull shape investigated by Sun et al [22] and Zakerdoost et al [23]. The total resistance is assumed to be the sum of the wave resistance computed on the basis of the thin-ship theory and the frictional resistance.…”
