AN OPTIMIZATION OF HULL FORMS FOR SHIP MOTION IN WAVES (2ND REPORT)

In a previous paper, the authors discussed a method to obtain the optimum hull forms which minimize ship motions in waves by using an approximate method for hydrodynamic forces. In this paper, the same problem to find the optimum hull forms is discussed by using more precise hydrodynamic forces and wave exciting forces, in which the so-called Ursell-Tasai's method is used for Lewis form cross sections. Furthermore, the wave making resistance in still water is also considered as the constraints in the optimization method and the resistance is evaluated from Michell's formula. An example of the numerical method is shown and the results discussed.
