Abstract

Commonly, the Computational Fluid Dynamic (CFD) analysis using the finite volume method, solid modeling is usually used in the early stage in order to prepare a mesh process before the computational process is executed. In this paper the CFD analysis must be executed to obtain a resistance coefficient value, and the verification should be done to ensure a result is close to experimental data. In the CFD analysis, some parameters have been taken into account, including the variation of domain dimensions, variation of mesh sizes, and variation of boundary conditions, in which the comparison between the numerical analysis and experimental data showed good agreement in general. The result of the case no.1 has a smaller difference of the resistance coefficients to the experimental data than other cases, in which the total resistance coefficient (Ct) has a difference about 1.95% of experimental data, the friction resistance (Cf) has a difference about 0.83% of experimental data, and there is a difference about 6.30% of experimental data for the residual resistance (Cr).

Abstract

Aceh's Banyak Island Due to its large water areas and fascinating islands that retain the grandeur of its sea and beaches, Singkil has risen as a new star in the world of tourism. Nonetheless, traditional fishing boats remain the principal mode of transportation for visitors in the region. The Glass Bottom Catamaran has been launched as a novel and attractive approach to admire the natural beauty of the seas around Banyak Island to capitalize on Indonesia's maritime tourist potential. The design process for this vessel involves basic linear regression calculations, the formulation of the ship's lines plan, the design of the vessel's General Arrangement, and the creation of a 3D model utilizing software. Stability calculations follow IMO standards, resistance calculations follow the Slender Body approach, and motion analysis follows Nordfork 1987 norms. As a result, the vessel's primary dimensions are as follows: LOA = 20.25 m, B = 7.04 m, B1 = 1.8 m, H = 2.4 m, T = 1.55 m, Vs = 17 knots, and a total passenger capacity of 54 people. In this investigation, the resistance value is 42.3 kN, concerning its ability to transport 60 tons at 17 knots. The stability study fulfils IMO guidelines, while the motion analysis meets Nordfork 1987 norms
