In the present study, numerical analysis algorithm for the hull form optimization was taken intoaccount using optimization algorithm. In this algorithm the sequential quadratic programming method wasapplied as an optimizer and the potential-based panel method was adopted to get the wave resistancecoefficient as the objective function. The hull form was modified using the B-spline surface modelingtechnique during the whole optimization process. The developed numerical analysis algorithm was appliedto the 300K VLCC and the optimized ship were compared with the original ship.
