“…Lately, more research has focused on the development and modification of ship performance, and the important objectives will focus on resistance and optimising the efficiency of the ship's propulsion system. Researchers need to keep the main objective under the maintenance, starting with the shape of the hull, wake fraction, interaction between hulls and propulsion systems, right up to the amount of the ship's operating costs (Carlton, 2007;Čerka et al, 2017;Zhang, Ma, & Ji, 2009). The main variables in the ship design process are Length (L), Beam (B), Draught (T), Coefficient block (Cb) and Velocity (V).…”

In the marine industry, specifically fast patrol boats, the important objectives are reducing resistance and improving the efficiency of ships' propulsion systems. The aim of this research was to investigate the application of a stern foil on a patrol boat through experimental and simulation methods. The stern foil used to generate a lift force was an asymmetrical National Advisory Committee for Aeronautics (NACA) foil. In the experiment, the stern foil was installed below the transom of a ship model and positioned parallel to the keel direction (3°towards x-axis). This position created a resultant force, which had an angle to the x-axis. There were variables in this experiment, such as the stern foil application, Froude number (Fr) and hull loads. Those combinations of variables generated sufficient data to analyse the effect of the stern foil working in various conditions. At an optimal load condition (half full load, 2 kg) and Fr 1.1 in the experiment and simulation, the ship model had a resistance reduction of as much as 22.3% and 23.3% in stern foil applications. In addition, with different setups of the stern foil (0°towards the x-axis) in the simulation, a resistance reduction of about 26.7% occurred at Fr 0.9.

“…Multi-objective surrogate-based hull-form optimization using high-fidelity Reynolds-Averaged Navier-Stokes Equations is presented in [8], whereas computational fluid dynamicsbased hull form optimization using the approximation method is reported in [9] and [10]. To quickly obtain practical ship forms with good resistance performance, the optimal design method of ship forms by using the non-linear programming method is presented in [11].…”

Owners of vessels are interested in the lowest possible operating costs. These costs are mainly related to fuel consumption during navigation. To manage it rationally, the main decision-making problem is selecting the proper parameters of the ship’s propulsion system during navigation. In practice, operators of ships equipped with controllable pitch propellers controlled in manual mode make a selection of the commanded outputs based on their own knowledge, intuition, and all accessible information regarding sea conditions. In many cases, their decisions are unreasonable or incorrect. Therefore, it would be desirable to support their decision-making in selecting the commanded outputs. For this reason, we have decided to develop a decision support system in the form of an expert system. This computer-aided system supports the selection of the commanded outputs of the ship’s propulsion system. The most important component of this system is the two-criteria optimization model, allowing the rational management of the ship fuel consumption and navigation time.

In this study, the effect of joint optimization of the principal dimensions and hull form on the hydrodynamic performance of a bulk carrier was studied. In the first part of the joint optimization process, fast principal-dimension optimization of the origin parent ship considering the integrated performance of ship resistance, seakeeping, and maneuverability, as well as their relationships with the principal dimensions were analyzed in detail based on the ship resistance, seakeeping qualities, and maneuverability empirical methods of Holtrop and Mennen, Bales, and K and T indices, respectively. A new parent ship was chosen from 496 sets of hulls after comprehensive consideration. In the remaining part, a further hull form optimization was performed on the new parent ship according to the minimum wave-making resistance. The obtained results demonstrate that: (a) For the case in which the principal dimension of the original parent-type ship is different from that of the owner’s target ship, within the bounds of the relevant constraints from the owner, an excellent parent ship can be obtained by principal-dimension optimization; (b) the joint optimization method considering the principal dimension and hull form optimization can further explore the optimization space and provide a better hull.
