Abstract
Waves, currents, and winds are important factors for safe and economic ship navigation, especially in coastal areas where ship density is relatively higher and the topography is more complicated. In this research, the eastern Seto Inland Sea, also known as the Harima Nada area, was selected for conducting numerical ship navigation. Ship traffic information was given from AIS, and WRF, SWAN, and POM models were used to produce numerical simulations of wind, waves, and currents, respectively.
The high-resolution weather and ocean information was then used to conduct numerical ship navigation. To verify their accuracy, results simulating the weather and ocean were compared with actual observation data. The findings showed that the estimation of a ship's position using the proposed numerical navigation simulation method was effective in helping a ship navigate safely and economically.
