## Abstract

The procedure given by Hsiung and Shenyan (1984) in formulating the objective function is adopted to a design procedure for the shape optimization of the forebody of vessels with protruding bulbous bows. In nonlinear programming methods, the objective function is taken as the total resistance approximated by the sum of frictional resistance and thin-ship wave resistance. Results of a case study are verified by tank tests. Mathematical programming with a proper set of constraints can substantially reduce the total resistance of commercial ships by optimizing protruding bulbs. The choice of initial hull form and the set of constraints are important for the success of the optimization procedure. The procedure removes guess work on hull form improvements and can find optimum solutions having commercial significance.
