Abstract
In this study, numerical investigation of ship resistance and ship motions at the traditional Indonesian fishing vessel is presented. The Computational Fluid Dynamic (CFD) code is used to calculate three dimensional, incompressible, and RANS equations. Different types of the fishing vessel hull form were performed. In this research, the data were collected chosen in north and south coast of Java island. The models were drawing in three dimensional, required for performing the analysis, were developed using Rhinoceros. The present study, the open-source computational fluid dynamics library, OpenFOAM was used to predict the resistance with the interFOAM solver. For the motion analysis, using strip theory in the Maxsurf motions. The probability of deck wetness analysis and ship motion were performed for comparing the models. Both analyses of ship Response Amplitude Operators (RAOs) are performed at three types of sea state (slight, moderate, and rough water). The comparisons of the hull form design will be evaluated to get the best performance based on the sea state condition of the java island.
Highlights
The traditional fishing vessel is one of transportation and livelihood support in Indonesia
The analysis was performed by interFOAM solver from the hull form design has an effect on resistance performance
The result was performed that the north coastal design has smaller added resistance than the south coastal design
Summary
The traditional fishing vessel is one of transportation and livelihood support in Indonesia. The traditional fishing vessel of region or island is one of the developed means product based on the ability to adapt to the natural environment in the region. The process of adaptation and culture of each island will determine the various forms of the traditional fishing vessel in terms of various size and style of the hull form. Indonesia has 17.508 islands, which is 70% of the sea with an area 5.8 million km. Indonesian sea is consists of 2.3 million km marine territory and million km Exclusive Economic Zone Area (EEZ)[1]. CFD is the computational fluid dynamics which based on potential flow theory, the Navier-Stokes equation to solve. The recent developments in computing technology have big problems to solve in shipbuilding industry
