Hydrodynamic Derivatives of a Ferry Ship Maneuvering in Deep and Shallow Water with Computational Fluid Dynamic Method

Abstract

Abstract The mathematical model and hydrodynamic derivatives can be developed in the simulation program to investigate a ship’s maneuvering performance using numerical simulation. This research describes a study to investigate the hydrodynamic derivatives of maneuvering a ferry ship in shallow and deep water. Using virtual drift and rotating arm model simulated, the hydrodynamic derivatives for a ferry ship’s surging, swaying, and yawing motions were obtained through Computational Fluid Dynamics (CFD). The hydrodynamic derivatives of the ferry ship were analyzed from the model test data using the least-square method. This study investigated three conditions of the ferry ship with various water depth conditions. The simulation result indicated that the ferry ship’s water depth affected its maneuvering performance.
