THE EFFECT OF HEADING ANGLE ON SHIP MANOEUVRING IN CONFINED WATER

Slender ship theory is a method of calculating a ship manoeuvring in confined water. In this theory, the fluid field around a ship hull is separated into the inner region and outer region and the velocity potential is obtained by matching the boundary of both regions. The hydrodynamic force acting on the ship hull also varies, while the ship's heading angle changes. Therefore the effect of the heading angle must be considered in the simulation. In this paper, calculation of the fluid force based on slender ship theory is described. Ship motion is simulated with and without the effect of the heading angle. It is shown that without the effect of the heading angle the fluid force calculated is smaller than with the heading angle.
