Experimental Investigation of the Hydrodynamic Force Acting on Ship Hull and Rudder in Various Wave Direction

Abstract

In the past, traditional methods of research on ship maneuvering performance were estimated in calm waters. However, the course-keeping ability and the maneuvering performance of a ship can be influenced by the presence of waves. Therefore, it is necessary to understand the maneuvering behavior of a ship in waves. In this paper, the prediction force acting on the rudder in calm waters was carried out and compared with those of CFD. Model test in regular wave was performed topredict the force acting on the ship and the rudder behind the model ship in various wave directions.
